A cylindrical vessel partially filled with water is rotated about its vertical central axis. It’s surface will

A long cylindrical vessel is half filled with a liquid. When the vessel is rotated about its own vertical axis, the liquid rises up near the wall. If the radius of vessel is 5 cm and its rotational speed is 2 rotations per second, then the difference in the heights between the centre and the sides, in cm, will be:

A long cylinderical vessel is half filled with a liquid. When the vessel is rotated about its own vertical axis. The liquid rises up near the wall. If the radius of vessel is 5 cm and its rotational speed is 2 rotatins per second, then the difference in the heights between the centre and the sides, in cm. will be :

If a horizontal cylindrical tube, partly filled with water is rapidly rotated about a vertical axis passing through its centre, the moment of inertia of the water about its axis will

As an empty vessel in filled with water, its frequency

A sphere of radius 9 cm is dropped into a cylindrical vessel partly filled with water . The radius of the vessel is 12 cm. If the sphere is submerged completely , then the surface of the water rises by :

A sphere of radius 6 cm is dropped into a cylindrical vessel partly filled with water. The radius of the vessel is 8 cm. If the sphere is submerged completely, then the surface of the water rises by
