A bullet passes past a person at a speed of `220 m s^-1`. Find the fractional change in the frequency of the whistling sound heard by the person as the bullet crosses the person. Speed of sound in air `= 330 m s^-1`.

A source emitting sound at frequency 4000 Hz, is moving along the Y-axis with a speed of 22 m s^-1 . A listener is situated on the ground at the position (660 m, 0). Find the frequency of the sound received by the listener at the instant the source crosses the origin. Speed of sound in air = 330 m s^-1 .

A train standing at the outer signal of a railway station blows a whistle of frequency 400 Hz in still air. The train begins to move with a speed of 30 m s^(- 1) towards the platform. The frequency of the sound heard by an observer standing on the platform is (Speed of sound in air = 330 m s^(-1) )
