The speed of sound in oxygen at $S.T.P.$ will be approximately: (Given,$R=8.3 \text{ J K}^{-1} \text{mol}^{-1}, \gamma=1.4$) (in $\text{ m/s}$)

The ratio of the speed of sound in hydrogen gas to the speed of sound in oxygen gas at the same temperature is

When a sound wave of frequency $300 Hz$ passes through a medium,the maximum displacement of a particle of the medium is $0.1 cm$. The maximum velocity of the particle is equal to:

Sound waves are not transmitted over long distances because:

Match Column - $A$ with Column - $B$.

Column - $A$	Column - $B$
$(a)$ Speed of longitudinal waves in gas and liquid.	$(i)$ $v = \sqrt{\frac{B}{\rho}}$
$(b)$ Speed of longitudinal waves in solid rod.	$(ii)$ $v = \sqrt{\frac{Y}{\rho}}$
$(c)$ Speed of sound in air according to Newton.	$(iii)$ $v = \sqrt{\frac{P}{\rho}}$
$(d)$ Speed of sound in air according to Laplace.	$(iv)$ $v = \sqrt{\frac{\gamma P}{\rho}}$

Sound waves travel at $350 \ m/s$ through warm air and at $3500 \ m/s$ through brass. The wavelength of a $700 \ Hz$ acoustic wave as it enters brass from warm air:
