Two identical cylindrical vessel with their bases at the same level each contain a liquid of density `rho`. The height of the liquid in one vessel is `h_(1)` and in the other is `h_(2)` the area of either base is A. What is the work done by gravity is equalising the levels when the two vessels are connected?

Two identical cylindrical vessels with their bases at the same level each, contain a liquid of density rho . The area of either base is A but in one vessel the liquid heigth is h_(1) and in the other liquid height is h_(2)(h_(2)lth_(1)) . If the two vessel are connected, the work done by gravity in equalizing the level is

Two identical cylindrical vessels with their bases at the same level each contain a liquid of density 1.30 xx 10^(3) kg//m^(3) . The area of each base is 4.25 cm^(2) , but in one vessel the liquid height is 0.854 m and in the other it is 1.560 m. Find the work done by the gravitational force in equalizing the levels when the two vessels are connected

Two identical cylindrical vessels are kept on the ground and each contain the same liquid of density d. The area of the base of both vessel is x_(1) and in the other, x_(2) . When both cylinders are connected through a pipe of negligible volume very close to the bottom, the liquid flows from one vessel to the other until it comes to equilibrium at a new height. The change in energy of the system in the process is :

Two identical cylindrical vessels have the same base area but are filled with different volumes of water . The forces on the bases of the two vessels are same .

A U-tube of cross section A and 2A contains liquid of density rho . Initially, the liquid in the two arms are held with a level difference h as shown in figure. After being released the levels equalize after some time. The work done by gravity forces on the liquid in the process is :

Two cylindrical vessels of equal cross sectional area A contain water upto heights h_1 and h_2 . The vessels are interconnected so that the levels in them become equal. Calculate the work done by the force of gravity during the process. The density of water is rho

A cylindrical vessel contains a liquid of density rho up to height h . The liquid is closed by a piston of mass m and area of cross section A . There is a small hole at the bottom of the vessel. The speed v with which the liquid comes out of the hole is
