In the figure shown cross-section area of holes are same and very small in comparison to area of cross-section of water tank : (tanks are the open from the top) Choose the correct option(s) :

Consider a water tank as shown in the figre. It's cross-sectional area is 0.4m^(2) . The tank has an opening B near the bottom whose cross-section area is 1 cm^2 . A load of 24kg is applied on the water at the top when the height of the water level is 40 cm above the bottom, the velocity of water combing out the opening B is v ms^(-1) . The value of v, to be nearest integer, is [Take value of g to be 10ms^(-2)]

A vertical tank, open at the top, is filled with a liquid and rests on a smooth horizontal surface. A small hole is opened at the centre of one side of the tank. The area of cross-section of the tank is N times the area of the hole, where N is a large number. Neglect mass of the tank itself. The initial acceleration of the tank is

Water is filled to height h in a fixed vertical cylinder placed on horizontal surface. At time t = 0 a small hole a drilled at a height h//4 from bottom of cylinder as shown. The cross section area of hole is a and the cross-section area of cylinder is A such that A gtgt a . The duration of time for which water flows out of hole is.

A cylindrical vessel of area of cross section A is filled with a liquid up to a height H . A very small hole of area of cross section a is made at the bottom of the vellel. Find the time taken by the vessel to become empty.

A cylindrical vessel of area of cross section A is filled with a liquid up to a height H . A very small hole of area of cross section a is made at the bottom of the vellel. Find the time taken by the vessel to become empty.

Name the unit used for measuring small area of cross section like nuclear cross section.

Water is filled to height h in a fixed vertical cylinder placed on horizontal surface. At time t = 0 a small hole a drilled at a height h//4 from bottom of cylinder as shown. The cross section area of hole is a and the cross-section area of cylinder is A such that A gtgt a . Let the value of horizontal distance of point where the4 water fall on horizontal surface from bottom of cylinder be x as shown. Then from time t = 0 till water comes out of hole, pick the correct statement:
