The speed of sound is 314 ms. The temperature of the surrounding atmosphere is -10°C. Calculate the speed of sound at `40^@C`.
[Hint: For every `1^@`C fall in temperature, the speed decreases by 0.6 m `s^(-1)`]

Text Solution

Verified by Experts

The speed of sound at `-10^@C` is v = 314 m `s^(-1)`
Increase in the velocity per `""^@C` fall in temperature is `Delta v=0.6 m s^(-1)`
Speed of sound at `40^@C`,
`v_(1) = v+Delta v(50) = 344 m s^(-1)`
