A man standing on a platform observes that the frequency of the sound of a whistle emitted by a train drops by 140 Hz. If the velocity of sound in air is 330 m/s and the speed of the train is 70 m/s, the frequency of the whistle is

An observer standing on a railway crossing receives frequencies 2.2 kHz and 1.8 kHz when the tran approaches and recedes from the observer. Find the velocity of the train (speed of sound in air is 300 m/s).

Two cars X and Y are approaching each other with velocities 36km/h and 72 km/h respectively. The frequency of a whistle sound as emitted by a passenger in car X, heard by the passenger in car Y is 1320 Hz. If the velocity of sound in air is 340 m/s, the actual frequency of the whistle sound produced is __________Hz.

The difference between the apparent frequencies of whistle as received by an observe in rest during approach to recession of the train is 1% . If velocity of sound is 320 m/sec, the velocity of the train is

Statement I: A person is standing near a railway trach. A train is moving on the track. As the train is approaching the person, apparent freqeuncy keeps on increasing and when the train has passed the person, then apparent freqeuncy keeps on decreasing. Statement II: When train is approaching the person then, f=f_0[(c )/(c-u)] and when train is moving away from person f=f_0[(c )/(c+u)] Here, c is velocity of sound u is velocity of train and f_0 is original frequency of whistle.
