Two sources A and B are sending notes of frequency 680 Hz. A listener moves from A to B with a constant velocity 'u'. If the speed of sound in air is 340 ms^(-1) , what must be the value 'u' so that he hears 10 beats per second ?

Two source A and B are producing notes of frequency 680 Hz. A listener moves from A to B with a constant velcoity v. if the speed of sound in air is 340 ms^(-1) , the value of y so that the hears 10 beats per second is

Two sources P and Q produce notes of frequency 660 Hz each. A listener moves from P to Q with a speed of 1 ms^(-1) . If the speed of sound is 330 m//s , then the number of beats heard by the listener per second willl be

A and B are two identical sound sources cachemitting a note of frequency 1000 Hz. A person moves from A to B along the line joining the two sources. How fast should be move to that he has 7 beats per second. velocity of sound 330 m/s ?

Two sources of sound S_(1) and S_(2) produce sound waves of same frequency 660 Hz . A listener is moving from source S_(1) towards S_(2) with a constant speed u m//s and he hears 10 beats/s. The velocity of sound is 330 m//s . Then, u equals :

A source emits sound with a frequency of 1000 Hz. It is moving at 20 m/s toward a stationary reflecting wall. If the speed of sound is 340 m/s an observer at rest directly behind the source hears a beat frequency of
