Two cyllindrical vessels of equal cross sectional ara 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 of cross section A contains water to a height h. There is a hole in the bottom of radius 'a'. The time in which it will be emptied is:

Water rises upto a height h in a capillary tube of radius r. What is the network done in this process if the density of water is rho ?

A cylindrical wooden block of density half the density of water is floating in water in a cylindrical container. The cross section of the wooden block. And its height are A and h respectively. The cross sectional area of the container is 2A. The wooden block is pushed vertically so that it gradually gets immersed in water. Calculate the amount of work done in pushing the block. Density of water =rho_(0) .

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?
