Previously we looked at uniform circular motion and the velocity of objects undergoing uniform circular motion. In this video we'll derive the acceleration of objects undergoing uniform circular motion, which is also known as the centripetal acceleration. This is a pretty involved derivation. Don't worry if it seems a bit complicated as you wouldn't be expected to invent it on your own without having seen it. So before we get started, how can an object undergoing uniform circular motion be accelerating if it's traveling at a constant speed? What we need to remember is that velocity is a vector. While it may be traveling at a constant speed, this vector is constantly changing direction for the object in question. Since the velocity is therefore changing, the object is accelerating. So let's find the acceleration of the object. Well, firstly we know that the acceleration a is equal to the change in velocity v divided by the change in time t. So let's try to work out what each one of these is separately. Let's start by working out the change in velocity delta v. Now you may be able to see that the change in velocity is dependent on where along the circle the object is. For example, if we waste for the object to undergo a complete revolution and looked at it in the exact same spot, then the change in velocity will be zero because it will be the exact same velocity vector. So what we really want to do is we want to find the instantaneous change in the velocity to find the instantaneous acceleration. So we're going to take a very, very tiny slice of the object's motion, infinitesimally small, to find the change in velocity at this point over the time it's taken to undergo this change. But to make our lives easier, we'll draw it far away, and we'll just understand this change is actually meant to be very small. Now, the velocity at the first point along the object's path will call v1, and the velocity at the second point along the object's path will call v2. So we're off to delta v, the change in velocity. This is the final velocity, v2, minus the initial velocity, v1. So let's draw it out. We now have a triangle three sides, v1, v2, and delta v. To get an expression with delta v, we'll need to work out some information about the angles and the sides of the triangle v1, v2, and delta v. We'll start by calling this angle theta. And remember that theta is really small as we work this out. Now, we're going to use some geometry to get the angle between v2 and minus v1. If we draw dashed lines out from our original v1 and v2 positions, we know that each of these dashed lines is perpendicular to the radial lines of the circle. We can find the angle in between our dashed lines by remembering that the sum of all angles in a quadrangle is 360 degrees. We know that two of these angles are 90 degrees, and the other one is theta, so the upper angle must be 180 degrees minus theta. Now, we also know that minus v1 in our triangle is parallel to the dashed line extension of v1, our original vector. Since angles on a line must sum to 180 degrees, we know that this angle here must be theta. And since we have two parallel lines, the angle between v2 and minus v1 will also be theta. This is known as the Alternate Angles Rule. So now we're going to zoom in on this triangle to work out an expression for theta. What else do we know about this triangle? Remember, we're considering uniform circular motion, so the speed is constant. This means that the length of v2 is equal to the length of v1, as these are both the magnitude of our velocity vector, and these are both equal to the speed v. As both of these sides are equal, we also know that our triangle is an isosceles triangle. Isosceles triangles can really help us out in problems, because if we cut it in half, we know that we'll get two right angle triangles. This means we can use Sokotoa, our trigonometry rule. So, if we consider our diagram, v is the hypotenuse, half of delta v is the opposite side, and the angle is half theta. So we can write sin of theta on 2 is equal to delta v on 2 divided by v. We can actually simplify this expression down even further by using the small angle approximation. Remember that theta is really, really tiny and infinitesimally small. The small angle approximation allows us to approximate sin of an angle as the angle itself. So sin of theta on 2 will be approximately equal to theta on 2. And for the limit case, which is the case we're considering, as we approach an infinitesimally small angle, sin theta on 2 will actually become theta on 2 exactly. So plugging this back in, we find theta on 2 is equal to delta v on 2 divided by v. Rearranging, we get that the change in velocity delta v is equal to v times theta. Therefore, we have the first ingredient for our acceleration. The change in velocity is equal to v theta. Now, let's move on to the second ingredient on our acceleration, which is the change in time. Since we know that the speed of our uniform circular motion is v, we can work out the change in time delta t from the distance it travels. So we'll redraw a diagram with the object at two points along the circle. Now, as we know from circle geometry, the length that the object travels is equal to the radius of the circle times theta, the angle in radians over which the object is traveled. Therefore, we can find that the distance the object has traveled is r times theta. We also know that the speed the object is traveling at is equal to v, the speed. We can now plug this back into our change in time to give us the change in time is equal to r theta on v. We now have expressions for both delta v and delta t, so we're almost there. So the acceleration is equal to the change in velocity over the change in time, and we're looking at an instantaneous moment in time. If we plug in our values, we find that our acceleration is equal to v theta divided by r theta divided by v. And if you cancel out the theaters and move the v up to the top, we get that the acceleration a is equal to the velocity v squared divided by r, the radius. We have now found the magnitude of the acceleration of an object undergoing uniform circular motion, also known as the centripetal acceleration. But we know that acceleration is a vector, so what about the direction? Well, the key factor to remember here is that the speed is constant. Now this means that there can't be any component of acceleration that is in the same direction as the velocity, otherwise the speed would change. We know from our previous velocity derivation that the velocity always points tangentially to the circle. This must mean that all of the acceleration must be perpendicular to the tangent, which is in the radial direction. The final bit we need to do is to figure out whether this acceleration is pointing radially inwards or radially outwards. Now we know that the acceleration must be in the same direction as delta v, our change in velocity, so if we draw out a triangle with v1, v2, and delta v, it's clear that delta v is pointing in towards the center of the circle and not away from the center of the circle. This means that the acceleration must point radially inwards. And there we have it. The acceleration of an object undergoing uniform circular motion is v squared on r and it points radially inwards. This is called the centripetal acceleration.


Good evening aspirants, welcome to daily news analysis brought to you by Shankar Iyer's Academy. Today's date is 27th January 2024. Displayed here are the list of topics we are going to see today. Now let us get into the discussion. Look at this news article. Recently the Supreme Court gave a landmark verdict in Bilki's Bono case. Know that the remission orders of love and convicts are cancelled by Supreme Court. It also asked them to go back to the prison within two weeks time. This case was regarding the Gujarat riots of 2002. So in this context the editorial discusses the ethical and legal part of remission. So let us understand the ethical issues involved in remission using our main censor writing approach. Now take a look at this main question. Discuss the concept of remission in criminal justice system highlighting its significance and challenges. And this is the syllabus regarding this topic. It comes under GS paper 4 ethical concerns and dilemmas in government and private institutions. See this question deals with ethical dilemmas. So in the first part it asks us to explain the significance of granting remission for prisoners and in the second part it demands the challenges of remission. So we can divide the answer into two parts. Now let us start with the introduction. In the introduction we can briefly explain about what is remission. Remission is a complete ending of sentence at a reduced point of time. To put it simply let us see a person yaks. If he is given life imprisonment by the court then the yaks spend 14 years in jail. After that he can ask for remission. It means he will be set free. Note that in remission the nature of sentence remains unchanged but the duration is shortened. The ethical basis of remission should be the ethics of forgiveness in the society. Moreover it was also articulated by Gandhi as hate the sin not the sinner. Now let us see the body part of the answer. In first part you should discuss about the significance in granting remission for prisoners. Firstly, remission ensures individual justice to the convicts. See individual justice mandates a fair chance to be given to rejoin the society. If the prisoner feels pity and remorse for his crime he can be given individual justice. This should be a cornerstone of any justice system as its base rests on moral development of individuals and society. Secondly, remission ensures compassion and humanity. See remission is an act of compassion by the courts or by the society. Note that many of the long term prisoners might face serious illness, old age sufferings so it is absolutely necessary to provide remissions on the ground of old age or health conditions and other compassionate reasons. Even though it is not a fundamental right of convicts this is the moral duty of the state to ensure it. Thirdly, remission prevents overcrowding in prisons. According to prison statistics in the year 2021 between 2016 and 2021 the number of convicts in the jails has increased by 9.5% whereas the number of under trial inmates has increased by 45.8%. So this shows the inhuman condition in our jails so naturally remission will reduce the issue of overcrowding in prisons. In this way it will provide the living condition for prisoners and improve the overall management of prison. Fourthly, remission will give a positive message for other prisoners. If the morally changed well behaved and reformed one is getting released it will change the attitude of other prisoners in a positive way. Finally, remission will also be economical to the state. This is because it will decrease the various costs associated with carrying of old prisoners and management of jail. With this we have completed the first part of body that is the significance of remission. Now let us see the second part of the body. Here we are going to discuss the challenges of remissions in the society. The first challenge is that it may lead to injustice to the victim. See an act of compassion towards a convict should not be insensitive to the victim of crime. The remission is even painful for the victims when the convict didn't feel remorse for their crimes or in some cases the prisoners are celebrated in the society when they are released. For example in Bilki's Bono case where the remission of convicts didn't take into account the sufferings of the victim. The second challenge is that the remission is often misused by political parties for their short term gains. This is evident in the hero worship of convicts in the society. The third challenge is the issue of discrimination based on social status. See the remission is often used by convicts from privileged backgrounds to get out of the jail. But sadly there are increasing number of under trails from marginalized communities in India. This should be balanced so that justice should not be an elite phenomenon. Fourthly there are challenges like lack of transparency in granting remission. And there is also lack of accountability with the process of remission. So this is the body part of the answer now we have come to the conclusion. We can write the conclusion in two ways. In one way we can write the way forward approach by following the guidelines given under Lakshman Naskar versus Union of India case in 2000. Let us see the guidelines provided under this case. Firstly we should ensure that the offence is an individual act of crime that does not affect the society. Secondly we should ensure that whether there is a chance of crime being repeated in the future. Thirdly ensure whether the convict has lost the potentiality to commit the crime. Fourthly we should also look into the socio-economic conditions of the convicts family before taking the decision. Now you can also give a conclusion like a general conclusion. Remission is an important relief of criminal justice system. Not only it allows for the reduction of sentence of a prisoner but also it gives a second chance for a person to live his life. But the ethical dilemmas of permission should be addressed to make it not only legal but also a moral remission. For this we should follow the principles of justice, mercy and public safety.  So with this let us conclude the discussion and more to the next topic. Look at this news article it talks about the concerns over proposed broadcasting services regulation bill 2023. This article is about the concerns regarding the broadcasting services bill. Let us see the important concerns surrounding this bill. Firstly know that the draft bill provides a regulatory provisions for various broadcasting services under a single legislative framework. Here the broadcasting services include cable TV direct to home that is DTH, terrestrial television, internet protocol television, FM radio, all-in-the-radio and community radio. So all this comes under broadcasting services. The bill also seeks to replace the existing cable television network Act 1995 and other policy guidelines currently governing the broadcasting sector in the country. This is to modernize the existing regulatory framework. Secondly the bill extends its regulation on over the top content that is OTT content and digital news and also current affairs. These things are currently regulated through IT Act 2000. Thirdly and most importantly the bill mandates every broadcaster or broadcasting network operator to establish one or more content evaluation committee that is CEC. This committee is like an internal committee within the organization and their purpose is to certify the programs to broadcast. In other words every broadcaster or broadcasting network operator can broadcast only those programs which are certified by the CEC that is content evaluation committee. But the issue here is that as per the text of the bill the central government will prescribe the number of members in CEC, the quorum required for the committee and other details that are required to facilitate the formation of CEC. So basically this committee will formed by the prescription of central government. The members of the committee can comprise of eminent individuals representing different social group and the central government will also provide the list of programs for which CEC should not give approval. So this raises issues like content censorship, publishers autonomy and it also affects the pull model where the consumers choose the content. Fourthly the bill mandates the broadcasters for the appointment of grievance redressal officer. He will receive and hear complaints in the violation of program code and the advertisement code. If the complainant is not satisfied with the decision of grievance redressal officer then he can appeal to the broadcast advisory council within the time limit. The time limit for this provision is not mentioned in the bill, it will be formulated soon by the central government. Implementing this provision could be a concern especially for smaller or resource constrained media outlets and these stringent regulations may unintentionally reduce the creativity and diverse opinions in the media. So these are the important concerns and provisions regarding the bill. With this let us conclude the discussion and move to the next topic. Look at this news article. Recently a fire broke out in Rathol coal mine in Nahaland. In this fire six workers were killed and four were seriously injured. So this raised a concern over illegal Rathol mining which has been going rampantly in this state. So in our discussion let us see about Rathol mining. This form of mining involves digging a narrow horizontal tunnels into the ground to extract the minerals from the ground. Here the tunnels are so small it is approximately 2 meter in diameter just around 1 to 4 feet.  So you can understand the relevance of the name here. Since this hole is very small they cannot use large equipment so they end up using small equipments to extract the coal. Now once the coal is taken out of the pit it is dumped on nearby unmined area. From there the coal is carried to the large dumping places for its trade and transportation. So this is how the Rathol mining is done. In India Rathol mining is mainly employed to extract the coal. So this method is typically used to extract coal from regions like Mehalaya and other northeastern states. States like Odisha, Mathya Pradesh, Chattiskirk and Jharkhand also have a lot of coal reserves. But in these states the Rathol mining is not employed. In Mehalaya the Rathol mining was employed due to several reasons. The first reason is a terrain and economic viability. The coal reserves in Mehalaya are very thin so this makes a traditional opencast mining in Mehalaya less economically feasible. So the Rathol mining was considered a more viable method. This is because it is believed to be more cost effective for extracting the coal from this region. The second reason is limited control over land. See Mehalaya is a sixth scheduled state where the coal mines nationalization act of 1973 does not apply to the state. So the landowners in Mehalaya also own the minerals beneath their land. So this results in limited government control over the mining activities in this region. So these are the main reasons why Rathol mining is employed in Mehalaya. See generally many hazards are associated with the coal mining process which increases the threat to miners. There will be risk of collapsing of mine troops, inundation of soil, fires in coal mines. So these are the important risks associated with Rathol mining. With this let us conclude the discussion and move to the next topic. Look at this front page article in order to mark the 25th anniversary of Indo-French partnership. Both countries agree to adopt a roadmap to set the course for bilateral relationship up to 2047. As a part of this plan, yesterday both the countries announced defense industrial roadmap. The roadmap aims to enhance cooperation on defense protection and future collaboration in co-designing and co-developing military hardware. Other agreements over the partnerships were in space, energy, digital health, agriculture, education and establishment of joint venture for local manufacturing of civilian helicopters for which Airbus and Tata have signed an agreement. So this is the crux of the article given here. In this context we are going to see about the bilateral defense ties between India and France. Firstly know that as of 2023 France is the second largest arms supplier to New Delhi. Nearly 30 percentage of arms required for India is imported from France. So this is as per Stockholm International Peace Research Institute report which is released in 2023. The first major defense tie is regarding Indian multi-role helicopter program. Saffron helicopter engine which belongs to France have concluded an agreement with Hindustan Aeronautics Ltd. This agreement is regarding the developing of critical components for heavy lift helicopters. The second major defense tie is with respect to Scorpion Submarine Construction Program which is also called P-75 Calvary Project. Project 75 intends to build six diesel electric attack submarines which belongs to Calvary class of submarines and this is based on French origin Scorpion class. So currently submarines are being constructed by Magason Dock Ltd. Thirdly as we all know in 2016 India has agreed to buy 36 Rafale jets from France for 59,000 crore. So the Rafale would be a great aid to joint strategic vision of India-France cooperation in Indian Ocean region. Fourthly the relations are further strengthened with the robust network of military dialogues and regularly held joint exercises. So there were three joint exercises between India and France that is Varuna which is a naval exercise and Garuda it is an air force exercise and lastly Shakti which is an army exercise. So these three are joint exercises between India and France. Apart from this France was among the first country which India signed a civil nuclear deal. France also played a critical role in limiting India's isolation in non-proliferation order after 1998 nuclear test. France also supports India's bid for permanent membership of United Nations Security Council as well as the entry of India into nuclear suppliers group. So this is all regarding this discussion now let us move to the next topic. Look at this news article it shows a photograph of golden tiger that was taken from Assam's Kasi Ranga National Park. This photo was shared by former chief minister of Assam on national tourism day. The tiger appears to be gold due to special mutation where the orange color of the tiger's body gets faded. So it appears in gold in color so this is why it is called as golden tiger and this is the crux of the article. So in this context let us quickly go through about Kasi Ranga National Park for our problem 6. As we all know Kasi Ranga National Park is situated in Assam and it is spread over two districts of Assam. This national park is present between the transition zone of Indo-Malayan biological realm. The Brahmaputra river flows through this park. Also note that Mora-Diplu river forms a southern boundary of Kasi Ranga National Park. The other notable rivers in the park Diplu river and Mora-Dansri river. So there are four major rivers which is flowing through this park. Now coming to the geology Kasi Ranga National Park has flat areas of fertile alluvial soil that was formed by erosion and deposition by the Brahmaputra river. The landscape of Kasi Ranga National Park has sandbars, riverine, flood formed lakes which are called as Bills. The riverine islands which is called as Chaporis. So the Chaporis provide shelter for animals during floods. See Kasi Ranga National Park is known for Big 5. The Big 5 refers to one-horned rhinos, elephants, Bengal tigers, Asiatic water buffaloes and swamp deer. Also note that Kasi Ranga National Park has two-third of old's great one-horned rhinoceros. So the largest population of one-horned rhinoceros is present in Kasi Ranga National Park. It also possess high density of tigers and has one of the largest populations of tiger in India. Note that it was declared as tiger reserve in 2006. The national park is also very important for wetlands and bird conservation. So it is also declared as important area for migrated birds. The bird life international has declared this national park as important bird area. So because of these significance the Kasi Ranga National Park was included in World Heritage Site by UNESCO in 1985 under natural category. So this is all about Kasi Ranga National Park. Now we have come to the prillims practice question discussion. Look at the first question. Cobbard National Park and Ganga River, this pair is incorrect. The river which flows through Cobbard National Park is Raman Ganga, Kasi Ranga National Park and Manas. This pair is also incorrect. In Kasi Ranga National Park as we have seen in the discussion Brahmabutra, Diplu, Mora Diplu, Mora Danshree are the main rivers that flows through Kasi Ranga National Park. Silent Valley National Park, Cauvery. This pair is also incorrect. Kundi Pula river flows through the Silent Valley National Park, Ratthambur National Park and Manas. This pair is correct. So the correct answer is option A, only one. Now look at the second question. It is a previous year question. Under which schedule of constitution of India can the transfer of tribal land to the private parties for mining be declared null and void? The correct answer is option B, fifth schedule. Now look at the third question. Raphael is a twin-engine multi-role fighter aircraft manufactured by Israel. These aircraft are capable of carrying out all combat missions. They can undertake interception, air defense, in-depth strikes, ground support, reconnaissance, anti-ship strikes including nuclear deterrence. So these are general points. As we know from the discussion, the first statement is incorrect. The Raphael is manufactured by France and not Israel. The other two statements are obviously correct. So the correct answer is option B, only two. With this, we have come to the end of the discussion.

Oh, God Have you ever thought each other's friends are hot? But none of your way It looks so good though. All right. Anyways Um, we're talking about like hometown friends or social media friends. Both. Have you ever thought one of my friends are hot? I think one of your hometown friends are but I'm not gonna say who. These are hot. Only one. Hot. Only one. Like attractive. Yes. What? I'm not gonna say who. I'm not gonna say who though. Well, I don't think that because I'm loyal I think all of Mariah's friends are ugly as balls. No, you don't. Bill always tells me. Oh, that girl's cute Okay, no, I don't say it that way. Come on. You're putting your hair. Don't lie. Okay, answer the question. Have you ever thought it? Yes or no? You are loyal to each other guys. Yes, I thought some of your friends were. Okay, exactly. Decently. Exactly. You know. Question and answer. Bing, bang, boom. Bing, bang, boom. Question number three. What is it? Have you ever have you showered together? Well, we live together. You caught us guys. We don't. You caught us. We look at work. We're showering right now. We're showering right now. Actually, this is counts. Here's a little privacy. I'm so uncomfortable right now. There's no easy way to fit two people in a small bathtub. It doesn't work, guys. This is why we need... It's why you need to get out of the bathroom. Want to leave? You can leave, actually. You can leave right now. You don't even have to be in here. Huh? You thinking about leaving? No. No? So, this is another top question. This is gonna be the last question and then we're gonna take a breather. Okay, what's your honest opinion on JD Vlogs and their upcoming wedding? We love JD Vlogs and we are super excited for their wedding. Every wedding is awesome. We can't wait. Every wedding. We love just seeing everybody's happy. Even Madeline Stevens wedding. We can't wait for freaking Sam and Jess's, Brian and Danielle's guys. We're just so excited.  When you watch someone and your friends with someone and you see them getting married, I feel like it's a total different experience.  Rather than not knowing that. I bought my eyes out and Madeline Stevens's wedding has been really involved with my freaking eyes out. It'll be good. I cannot wait for the video to come out. I'm excited. So, we're gonna do one more, so we're gonna do one more, because, you know... What's the first thing you found attractive about each other? So, this is the last question now. The first thing that I found attractive about you, I think was... You were just beautiful. I mean, obviously your looks, but I think it was also because you were a twin, so it kind of made it a little more... Hotter? A little more juicy. Not that I like your sister, just... Oh, what do you find attractive about me? Like, on my face? Your whole figure. Your whole figure? Your figure. When you wore those maria out of jeans. Okay, okay. Woo! Mom, it's fine. Don't even get me started on that. The answer for me, I will say, I don't know why were your eyes and your lips, I just found real...   You can see it right now. You're not even after them. Let me win. It's been three and a half hours. You put your eyes and your lips. Ooh, my eyes and my lips. Yeah, you just have really nice lips. She likes my lips, guys. See, that's the point for Bill. No. Hey, what would you do? Brian, if I turned on the shower right now? Don't. What would you do? I would not pop you. Wait, would I win if I turned on the shower right now? What? Where are you going? That's fun.  Look at that. I'll see you when I'm smiling. See you in another three hours. No! No! Stop! Why would you do that? Mariah, it's half wet in my bed.  Sorry, I'm having a hard time. It literally went from here to that way. Now what?  You have nowhere to lay down. Where are you going to sleep tonight? We have to sleep. We have 21 hours left of this challenge. It's all right. I'm trying to win. I'm trying to win. I'm not moving. Okay. I'm going to turn the shower on then. No, you're not. I'm not going to let you know. Stay tuned. I've been trying to do stretches because I'm actually getting really tired. I need to keep myself awake. I need to keep stamina going. This girl, this beautiful little face right here. She's every single hour. She gets a little winger in here.  You can leave right now, babe. You can go out there. No, I need to stay awake. I'm literally feeling it now. Four hours and we made it to the 20 hour. I'm going to sleep this whole thing through. Three hours, though. We made it to the 20 hour. We made it to the 20 hour. 20 hours left. My God. I feel like I'm going crazy. I'm really tired right now. I know. We should have thought about like dinner. I know. I'm exhausted.  It's fresh air. Oh my God. Alright, we can't. We can't. I can't tease it. It actually smells different out there. It smells way better out there. It smells way better out there. Probably for me farting earlier. If I could do it again, I would, right now. No, don't. I'll probably end up cramping myself. Don't. That's so nasty. Alright, guys. I'm going to try to keep myself awake. We'll see how it goes. I did a workout today and I'm getting cramped up, so. Not a fun time for me. I'm going to bed. Good night, guys. So, I just woke up from our nap. It's been three hours. We have 17 hours left to go.  I'm getting clausophobic. I want to just go in my actual bed. I don't want to be sitting here anymore. And if you guys remember, I said, stay tuned since he's asleep. It's the perfect time to do this.  I'm so sorry, babe. But Team Araya has to win this challenge. If he does not leave this bathroom, oh my God, I'm doomed because I don't know anything else that I could do to make him leave. So, wish me luck and let's go turn on the shower. Oh, poor Bill. There's no idea what I'm doing. He has his cute little piece. Hey. What are you doing?  There you go. Turn it off. How are you feeling? What's up? Are you really mad? What is wrong with you?  What is wrong with you? Oh my gosh, guys. He is sitting in a bath. Oh my God, your feet are basically underwater.  Three hours later. You literally soaked my blanket. Oh, well, well. Are you done with the bathroom? How many? Three hours and 14 minutes. Yes.  I want to get out of here. So, is this, are you giving up now? What am I saying? I'm all soaked. What are you going to do? That's not even fair. Like, how are you even going to lay in here? I don't know. You tell me. How do you feel, babe? What? I feel like- I'm so sore. I'm going to get you back. I'm not leaving. You're not leaving? You're really going to stay in here soaking wet? Can you turn off the light or something? No.  Look, babe. Oh my God, baby. Look, you can leave. I'm not leaving. You can leave. Get some fresh air. Go change some new clothes. Dry up. You want to stay here and sit down here? I'm just off. I am right now. We're 17 hours- I cannot believe you actually- We have 17 hours left. Are you giving up? No, I'm not giving up. We have 17 hours left? Mm-hmm. Oh my God. Mm-hmm. No, I came too far. I came too far.  Come on.  I'm trying to- Dude. Dude, I'm freaking- Show the camera just for a sec. Dude, no. Can you move please?  Please, Liz, please leave. Please stop. Please leave. Please stop before I- Leave. Come on. I want to get out of here. I'm getting claustrophobic and annoying. This is so loud. Please. All right, guys. Bill's finally out of the tub. You're really not packing out on this? You're really staying- You're sitting here? I'm staying in here. Marvel Squad. My plan is ruined. My plan is ruined. Stay tuned. I look way up.  I'm not going to bed. Oh, I'm not done. You know what? That woke me up. I'm not going to bed anymore. I was hoping that would really make you- I'm still tired, but no. That's not working. Dude. You had barely slept. Did you even sleep at all? No, I did. I was hoping to make you leave. I'm hungry. Look, yeah. You woke up early. I'm hungry and I want food.  Geez, babe. You poured water on me, guys. I was hoping that would make you want to leave. My socks are soaked. My socks are soaked. My naughty towel. My blanket. The towel is less damp than the blanket is. But, guys. What are you doing? Nothing. What are you doing? Okay, nothing. Ease wrapper. Can you stop? What are you doing? Nothing. What are you doing, stupid? Huh? What do you got? What do you got? What do you got, babe? All right. I might have put a bug in the container earlier. No, you did it.  No, you did it. No, you did it. Don't freak out. Babe, babe, babe. I told you if you do any bugs, we're going to break out. Okay, well, I'm trying to win this challenge. All right? No. Ready? Oh, my God. I should have kept it going. You would have left. Come on, please. No. Oh. We're closer. I think it broke.  I'm not losing. I'm not losing no matter what. Stop working. All right. So, we're getting tired up in here, guys. It's actually getting really difficult now, especially after that wet. An hour has passed since we last talked. My pants are dry now. They're thin. And you've got to be wet. Only on my pants is I'm happy with. My socks are still soaked, but they're dry enough as well.  And I want to end this video right now. What? Huh? What do you want to do? I'm locking the door. I'm locking you in there. It's no good enough. I know. Okay. But yeah, look at it. Do we still have empty food? I don't know what to do. Mariah is yawning over here. What? I'm tired. Can you move? Why? Can you move? I just want to sit down here. Why? You can go on the ground. Why do you need to sit there? Just go on the ground. Why do you need to sit there? I love you. Give me a kiss. Why do you need to sit there? I love you. Why do you need to sit there? Just let me sit here. Oh my God. I don't want to sit. You're annoying. Is that illegal to want to sit? Yes.  I know. God.  Please do not tell me you're actually going to the bathroom right now. What? Please do not tell me you're going to the bathroom right now. Why are you not actually going? Is this actually going to make you leave? Ew. But guys, we have, what, 16 hours to go and what? What are you doing? Nothing. I'm just chilling. A man's got to go to the bathroom. Oh, God. This is so cheating. This is so cheating because now I have to smell the poop. You're fine. You're fine. I throw it up. I throw it up.  I should have done this. I'm out. I'm out.  Oh, my God. Right. You guys just lost. Yes, I did. And you know what? That was cheating. How are you going to take a dookie in the bathroom with me and they're like that? You literally stayed in here for eight hours. I have no idea how disgusted I am right now. I feel lighter, guys.  We spent eight hours in a bathroom and you ended for a turn.  It's freaking guys, you don't understand.  Not gonna lie, I did not think about that until a half hour ago and I didn't have to go. So when I finally had to go, I had to bring up the camera and do it. I know every time I go to the bathroom, Mariah literally goes on the other end of the house just because whenever she smelled anything, even for our cat, literally goes crazy. Just like that end, babe. You ended it after eight hours. Look it, guys, it's already sunset. The light is already, you can see the sunset in there. It's about to be dark. That was just so bad.  I'm actually throwing up.   Oh my God, guys. I mean, I beg to differ on that, but I'm just saying. Babe, you're so, guys, I hope you enjoyed this challenge. I won, I literally, I was not thinking I was gonna win after the air horn failed, because that was my key to victory. But once I thought of taking a dookie in the same bathroom as you, I was like, why didn't I not think about this like five hours ago? So freaky. Hey, but we can all say that we spent, we made ourselves a record, babe. Eight hours in the bathroom is pretty damn good, right? I will give it to you. Give me some notes. Eight hours is good. High five. It's better than 20 frogs. I'm so glad you did that honestly, because I was about to leave. Hey, tell us your longest time you've been in the bathroom before. Comment down below because. I don't think anybody's ever been in the bathroom in a longer than what, an hour? I get caught up sometimes an hour and a half. I've been in the bathroom before this. Geez, babe. Yeah, I don't know.

It is every sailor's responsibility to give back to the community. Petty Officer Zach Shea shows us how the USS Frank Cable services their community in Guam. Sailors assigned to the submarine tender USS Frank Cable volunteered during their free time at Marseille A. Sablon Elementary School for an ongoing revitalization effort. I actually like giving to the community. I like helping people. It's not just about joining the military and saying that's doing enough. Going out there and helping the community to get better no matter where you're stationed at you can always make a difference at least to one person at a time. Sailors painted stairwells and added multiplication tables and hopscotch courses to the recess areas. From USS Frank Cable in Santa Rita Guam, I'm Petty Officer Zach Shea.
