A vessel, whose bottom has round holes with diameter 0.1 mm is filled with water. The maximum height upto which water can be filled without leakage is (S.T. = 75 dynes/cm and g = 1000 cm/s²)

If a liquid is placed in a vertical cylindrical vessel and the vessel is rotated about its axis, the liquid will take the shape of Fig.

Which molecule of a liquid has higher potential energy?

A solid sphere falls with a terminal velocity of 10 m/s in air. If it is allowed to fall in vacuum

A spherical ball of iron of radius 2 mm is falling through a column of glycerine. If densities of glycerine and iron are respectively 1.3 × 10³ kg/m³ and 8 × 10³ kg/m³. η for glycerine = 0.83 kg/m.sec, then the terminal velocity is

A flat plate of area 10 cm² is separated from a large plate by a layer of glycerine 1 mm thick. If the coefficient of viscosity of glycerine is 20 poise, the force required to keep the plate moving with a velocity of 1 cm per sec is

From amongst the following curves, which one shows the variation of the velocity V with time t for a small sized spherical body falling vertically in a long column of a viscous liquid

The vertical sections of a wing of a fan are shown. Maximum upthrust is in

A small spherical solid ball is dropped from a great height in a viscous liquid. Its journey in the liquid is best described in the diagram given below (V = velocity and t = time) by the

Three tubes A, B and C are connected to a horizontal pipe in which liquid is flowing. The radii of pipe at the joints of A, B and C are 2 cm, 1 cm and 2 cm respectively. The height of liquid
