Will there be any Doppler shift when source and listener move in the same direction with the same velocity ?

Will there be any Doppler whift when source and listener move in the same direction with the same velocity /

A source of sound moves towards a listener with a velocity equal to that of sound. If the source emits n waves per second, then the listener moving away from the source with the same velocity receives

When the listener moves towards a stationary source with a velocity v_(1) m the apparent freqency of a note emitted by the source is f' When the listener moves away from the source with the same velocity, the apparent frequency of the note f/f'=3. If v the velocity of sound in air, the value of v//v_(1) is -

When are the velocity and acceleration in the same direction SHM?

A body A moves with a uniform acceleration a and zero initial velocity. Another body B, starts from the same point moves in the same direction with a constant velocity v. The two bodies meet after a time t. The value of t is

The two waves of same frequency moving in the same direction give rise to

Assertion : There will be no Doppler effect,when both the source and listener are at rest and wind alone is blowing Reason :The blowing wind does not change the distance between the source and listener which is a must for Doppler effect.

When are the diplacement and velocity in the same direction in SHM?

Two parallel beams of positrons moving in the same direction will
