Q. The speed of sound in gas of density ρ at a pressure p is proportional to
A) $\left( \frac{p}{\rho} \right)^{2}\
$
B) $\left( \frac{p}{\rho} \right)^{\frac{3}{2}}$
C) $\sqrt{\frac{\rho}{p}}$
D) $\sqrt{\frac{p}{\rho}}$
Explanation
(d) We knows
$c = \sqrt{\frac{\gamma p}{\rho}}$
$c = \left( \frac{p}{\rho} \right)^{1/2}$
