A cylinder full of water is placed just below a container. Water drops come out of the bottom of container at a regular interval of time and strike water surface in tank with velocity `v_(0)`. If `f_(0)` is the frequency of sound produced, then frequency of sound received by the oberver at rest, is

A large tank containing water has a small hole near the bottom of the tank 1.5 m below the surface of water. What is the velocity of water flowing from the hole?

A large tank containing water has a small hole near the bottom of the tank 1.5 m below the surface of water. Explain the principle used in deriving the velocity of water flowing from the hole.

A sound source is falling under gravity. At some time = 0, the detector lies vertically below the source at a depth H as shown. If v is the velocity of sound and f_(0) is frequency of the source, then the apparent frequency recorded after t = 2s is

A tank containing water has an orifice in one vertical side. If the centre of orifice is 4.9 m below the surface level in the tank, the velocity of discharge is:

A tank containing water has an orifice in one vertical side. If the centre of orifice is 4.9 m below the surface level in the tank, the velocity of discharge is:

A tank containing water has an orifice in one vertical side. If the centre of orifice is 4.9 m below the surface level in the tank, the velocity of discharge is:

The observer is moving with velocity 'v'_(0) towards the stationary source of sound and then after crossing moves away from the source with velocity 'v'_(0) . Assume that the medium through which the sound waves travel is at rest. If v is the velocity of sound and n is the frequency emitted by the source, then the difference between appearent frequencies heard by the observer is
