Physics - Sound Wave Question with Solution | TestHub

The speed of sound is given by, 

$$\begin{gathered} v=\sqrt{\frac{\gamma RT}{M}} \\ =\sqrt{\frac{1.4\times 8.3\times 273}{32\times {10}^{-3}}} \end{gathered}$$

$=314.8541\simeq 315 \mathrm{m} {\mathrm{s}}^{-1}$

Nearest answer given in the option is $310 \mathrm{m} {\mathrm{s}}^{-1}$.
