two trains move towards each other sith the same speed. The speed of sound is 340 m/s. If the height of the tone of the whistle of one of them heard on the other changes

Two trains moves towards each other with the same speed. Speed of sound is 340 m//s^(-1) . If the pitch of the tone of the whistle of one when heard on the end other changes to 9//8 times, then the speed of each train is :

Two trains move towards each other with the same speed. Speed of sound is 340ms^(-1) . Frequency of tone of the whistle of one when heard by the other changes 9/8 times, then the speed of each trains is

The sound of thunder is heard 3 s after flash of lightning. If the speed of sound is 340 m/s, find the height of the cloud.

A car, sounding a horn of frequency 1000 Hz, is moving directly towards a huge wall at a speed of 15 m/s. If speed of sound is 340 m/s, then the frequency of the echo heard by the driver is

Two trains are travelling towards each other both at a speed of 90 km h^-1 . If one of the trains sounds a whistle at 500 Hz, what will be the apparent frequency heard in the other train ? Speed of sound in air = 350 m s^-1.
