When an engine passes near to a stationary observer then its apparent frequencies occurs in the ratio 5/3. if the velocity of sound is 340 m/s then speed of engine is

The apparent frequency of the whistle of an engine changes in the ratio 9 : 5 as the engine passes the stationary observer. If the velocity of sound is 350 ms^(-1) , then the speed of the engine is

A train moving at 40 m/s, passes by a stationary observer, emitting a whistle of frequency 300 Hz. If the velocity of sound wave is 340 m/s, then the change in the apparent frequency of the sound, just before and after the train passes by the observer will be nearly

The difference between the apparent frequencies of a source of sound as perceived by a stationary observer during its approach and recession is 2%of the actual frequency of the source. If the speed of sound is 300 m/s, the speed of the source is

The apparent frequency of the whistle of an engine changes in the ratio 6:5 as the engine passes a stationary observer. If the velocity of the sound is 330 m/s then the velocity of the engine will be

The apparent frequency of the whistle of an engine changes in the ratio 6:5 as the engine passes a stationary observer. If the velocity of sound is 330(m)/(s) , then the velocity of the engine is

The apparent frequency of the whistle of an engine changes in the ratio 6:5 as the engine passes a stationary observer. If the velocity of sound is 330(m)/(s) , then the velocity of the engine is

The frequency of the whistle of an engine appears to drop to (2)/(3)rd of its actual value when it passes a stationary observer. Velocity of sound in air is 330 m/s then the speed of engine is
