Air temperature in the Rajasthan deserrt can reach 46^(@)C. What is the velocity of sound in air at that temperature ? (V_(0)=331ms^(-1)).

Answer»

Solution :VELOCITY of sound `v_(0)=331ms^(-1)`
AIR TEMPERATURE , `T=46^(@)C`
Velocity of sound in air temperature `v_(T)=(v_(0)+0.61T)ms^(-1)`
`=331+(0.61xx46)`
`=331+28.06`
`v_(T)=359.06ms^(-1)`
