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 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 )

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).

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).

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).

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 ) ?

A train sounds its whistle as it approaches and crosses a level crossing. An observer at the crossing measures a frequency of 219 Hz as the train approaches and a frequency of 184 Hz as it leaves. If the speed of sound is taken to be 340m//s , find the speed of the train and the frequency of its whistle

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 .

Two trains A and B are approaching a platform from opposite directions. The siren in the station is making a sound at a frequency 4 kHz. The passengers in trains A and B hear siren at frequencies 4.5 and 5 kHz respectively. Then the velocities of the trains A and B are (velocity of sound in air = 340 m//s)
