At each of two stations A and B, a siren is sounding with a constant frequency of 250 cycle `s^-1`. A cyclist from A proceeds straight towards B with a velocity of `12kmh^-1` and hear `5 beats//s`. The velocity of sound is nearly:

At each of the stations A and B a siren its surrounding with a constant of frequency pf 250 Hz.A cyclist from A proceeds towards B with a velocity 12km/hr and hears 5 beats per second.Calculate the velocity of sound.

Two sound waves of wavelength 10 m and 10.1 m produces 0.33 beats/s. Then the velocity of sound is

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 :

Two source of sound S1 and S2 produce sound waves of same frequency 660 Hz. A listener is moving from source S1 towards S2 with a constant speed um/s and he hears 10 beat/s. Then, u is equal to ________ (in m/s).

A siren emitting sound of frequency 800 Hz is going away from a static listener with a speed of 30 m/s. Frequency of the sound to be heard by the listener is (Take velocity of sound as 330 m/s)

A siren emitting sound of frequency 800 Hz is going away from a static listener with a speed of 30 m/s. Frequency of the sound to be heard by the listener is ( Take velocity of sound as 300 m/s )

A siren emitting sound of frequency 800 Hz is going away from a static listener with a speed of 30 m/s. Frequency of the sound to be heard by the listener is ( Take velocity of sound as 300 m/s )
