A car sounding its horn at `480Hz` moves towards a high wall at a speed of `20ms^(-1)`, the frequency of the reflected sound heard by the man sitting in the car will be nearest to , (speed of sound `=330m//s)`

A car sounding its horn at 480 Hz moves towards a high wall at a speed of 20 m/s, the frequency of the reflected sound heard by the man sitting in the car will be nearest to :

A car sounding its horn at 480 Hz moves towards a high wall at a speed of 20 ms^-1 . If the speed of sound is 340 ms^-1 , the frequency of the reflected sound heard by the passenger sitting in the car will be nearest to

A car with a horn of frequency 620 Hz travels towards a large wall at a speed of 20 ms^(-1) the frequency of echo of sound as heard by the driver is x xx10^2Hz , what is the value of x (velocity of sound -330m/s

A car is moving towards a fixed wall, it blows form of frequency of 440 Hz . The frequency of reflected sound observed by the driver is 480 Hz then find the speed of car in km/hr. (Speed of sound is 350 m/sec
