The ratio of the speed of sound in nitrogen gas to that in helium gas, at 300 K, isA.B.C.D.

The ratio of densities of oxygen and nitrogen at a given temperature is 16 : 14. The ratio of speed of sound in oxygen and nitrogen at that temperature is

A sound wave in helium has an intensity of 1.00 × 10−3 W/m2. The density of helium is 0.179 kg/m3 and the speed of sound in helium is 965 m/s. The pressure amplitude of the sound wave is

The speed of sound in oxygen at S.T.P. will be approximately:
