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).

A whistling train approaches a junction. An observer standing at juction observes the frequency to be 2.2 KHz and 1.8 KHz of the approaching and the receding train respectively. Find the speed of the train (speed of sound 300m//s )

A whistling train approaches a junction. An observer standing at juction obsrever the frequency to be 2.2 KHz and 1.8 KHz of the approaching and the receding train respectively. Find the speed of the train (speed of sound 300m//s )

A man stands on a railway crossing and when a train approaches and recedes from him, he receives frequencies of 2.4 kHz and 1.8 kHz, respectively. Determine the velocity of the train. Take, Speed of sound in air = 320 m/s

The ratio of the apparent frequencies of a car when approaching and receding a stationary observer is 11:9 What is the speed of the car, if the velocity of sound in air is 330 m/s?

The ratio of the apparent frequencies of a car when approaching and receding a stationary observer is 11:9 What is the speed of the car, if the velocity of sound in air is 330 m/s?

A train is passing a stationary observer at station with constant velcity. If the frequency observed by the person during its approches and recession are 2.2 kHz and 1.8 kHz respectively. Then find the velocity of train if the velocity of sound in air in air is 300 m//s .

An observer standing at station observes frequency 219 Hz when a train approaches and 184 Hz when train goes away from him. If velocity of sound in air is 340m//s , then velocity of train and actual frequency of whistle will be

An engine giving whistle is moving towards a stationary observer with 110m//s speed. What will be the ratio of the frequency of the whistle heard when the engine is approaching and receding from the observer (the speed of sound is 330 m//s ) ?
