How Old Does Child Have To Be To Sit In Front Of Car? In an appropriate seat any age- DO NOT USE A REAR FACING CAR SEAT ON THE FRONT SEAT, EVER!!! 12 is the recommended minimum age. If you must put a child in the front seat though, the safest option is to put a child in a harnessed seat, with the air bags off and the seat pushed all the way back. Air bags are NOT nice and can still go off when disabled. 08-06-12, 17:52 #4. Leigh C(136) View Profile.

What are menstruation, periods, and PMS? The period consists of a small amount of blood and the endometrium. The bleeding is caused by the breaking of fine blood vessels within the womb as the lining detaches itself. A period generally lasts about five days. Bleeding is more profuse during the first two days.

Ovulation occurs in the middle of the menstrual cycle and usually takes place every 28 days or so in a mature female. It takes place from either the right or left ovary at random.

They may occasionally start as early as eight, and this onset may still be normal. The average age of the first period is generally later in the developing world and earlier in developed world. The typical length of time between the first day of one period and the first day of the next is 21 to 45 days in young women and 21 to 31 days in adults (an average of 28 days). Menstruation stops occurring after menopause which usually occurs between 45 and 55 years of age. Bleeding usually lasts around 2 to 7 days.

Menstruation Menstruation, or period, is normal vaginal bleeding that occurs as part of a woman's monthly cycle. Every month, your body prepares for pregnancy. If no pregnancy occurs, the uterus, or womb, sheds its lining. The menstrual blood is partly blood and partly tissue from inside the uterus. It passes out of the body through the vagina. Periods usually start between age 11 and 14 and continue until menopause at about age 51. They usually last from three to five days.

- The period is a around trip and hence twice the amount of time it takes to travel through the Earth. So we will need to divide the period by 2. Before we plug in the numbers, notice that it doesn’t matter how heavy you are. Big or little, you it takes the same amount of time to fall.

Frequency and Period of a Wave The period of a wave is the time for a particle on a medium to make one complete vibrational cycle. Period, being a time, is measured in units of time such as seconds, hours, days or years. The period of orbit for the Earth around the Sun is approximately 365 days; it takes 365 days for the Earth to complete a cycle.nswer: 0.0195 sec. Here is an example of a problem with a lot of extraneous information. The period is simply the reciprocal of the frequency. In this case, the period is 1/(51.2 Hz) which is 0.0195 seconds.

What is period???? Best Answer: Hi, You mean monthly period of girls. Monthly period is called Menstruation. Mestruation is a normal part of a woman’s reproductive cycle. The ovary periodically releases an egg. It also releases a hormone called oestrogen, which stimulates the lining of the uterus to grow and get prepared to receive the fertilized egg. If, however, the egg does not get fertilized, the uterus sheds its lining resulting in menstrual flow. This flow repeats itself in a cycle of approximately 28 days until a woman gets pregnant or has approached menopause.
