At sea level this about 761 miles per hour.
In SI units and under standard conditions for air, this is equal to 20.05 times the square root of the temperature, but usually an approximation using a reference plus 0.6 times the temperature is used. This is equal to the square root of the ratio of bulk modulus to density. When this is exceeded a shock wave is created. At sea level this about 761 miles per hour. The ratio of an objects velocity to this is called the Mach number. For 10 points, name this quantity which is the rate at which an acoustic wave travels.
