The velocity of a listener who is moving away from a stationary source of sound such that the listener notices 5% apparent decrease in frequency of sound is (Velocity of sound in air =340m//s)

The velocity of a listener who is moving away from a stationary source

1.	The velocity of a listener who is moving away from a stationary source of sound such that the listener notices 5% apparent decrease in frequency of sound is (Velocity of sound in air =340m//s)
Answer» `12.5ms^(-1)` `17ms^(-1)` `25ms^(-1)` `34ms^(-1)` SOLUTION :`N.=n((V-V_(0))/(V))` Here `n.=(95)/(100)n`
