A) 330 m/s
B) 165 m/s
C) \[[{{M}^{0}}{{L}^{0}}{{T}^{0}}]\]
D) \[{{k}_{\alpha }}\] m/s
Correct Answer: C
Solution :
As there is no effect of change in pressure on velocity of sound in air, and velocity \[250\sqrt{2}{{\mu }_{0}}\]therefore, when temperature is doubled, velocity becomes \[\left[ ie\left( \frac{Q}{W} \right) \right]\]
