A whistle is whirled in a circle of radius 1m with 7rps. An observer is situated outside the circle, but in its plane. If the speed of sound is 336`m//s`, find the interval between the highest and lowest observed pitches.

A blowing whistle is performing a uniform circular motion in a horizontal circle of radius r. An observer standing outside the circular parth,

To an observer, the pitch of a stationary source of sound appears to be reduced by 20%. If the speed of sound is 340m/s then speed and direction of the observer is

To an observer, the pitch of a stationary source of sound appears to be reduced by 20%. If the speed of sound is 340m/s then speed and direction of the observer is

A whistle emitting a loud sound of frequency 540 Hz is whirled in a horizontal circle of radius 2 m and at a constant angular speed of 15 rad//s . The speed of sound is 330 m//s . The ratio of the highest to the lowest frequency heard by a listener standing at rest at a large distance from the center of the circle is

An observer A fires a gun and another observer B at a distance 1650 m away from A hears its sound. If the speed of sound is 330 m/s, Find the time when B will hear the sound after firing by A.

An observer A fires a gun and another observer B at a distance 1650 m away from A hears its sound. If the speed of sound is 330 m s^(-1) , find the time when B will hear the sound after firing by A.

The time interval between a lightning flash and the first sound of thunder is 5 s. If the speed of sound in air is 330 m s^(-1) , find the distance of flash from the observer.
