A steel ball floats in a vessel with mercury. How will the volume of the part of the ball submerged in mercury change if a layer of water completely covering the ball is poured above the mercury?

A steel ball floats in a vessel with mercury. How will be volume of the part of the ball submerged in mercury change if a layer of water completely covering the ball is poured above the mercury? If rho_(w), rho_(s) and rho_(m) are the densities of water, steel and mercury, find the ratio of these two volumes in terms in of rho_(w), rho_(s) and rho_(m) .

A cubic body floats on mercury with 0.25 fraction of its volume below the surface. What fraction of the volume of the body will be immeresed in the mercury if a layer of water poured on top of the mercury covers the body conpletely.

A steel ball is floating in a trough of mercuty. If we fill the empty part of the trough with water, what will happen to the steel ball ?

A solid body floats on mercury with a part of its volume below the surface . Will the fractional volume of the body immersed in mercury increase or decrese, if a layer of water poured on the top of mercury covers the body completely?\

A piece of steel floats in mercury. The specific gravity of mercury and steel are 13.6 and 7.8 respectively. For covering the whole piece some water is filled above the mercury. What part of the piece is inside the mercury

A cylinder of iron floats vertically and fully immersed in a vessel containing mercury and water. Find the ratio of the length of the cylinder immersed in water to that immersed in mercury. (Relative density of mercury = 13.6 and that of iron = 7.78)

Two communicating vessels contain mercury. The diameter of one vessel in n times larger then the diameter of the other. A column of water of height h is poured into the left vessel. The mercury level will rise in the right hand vessel (s = relative density of mercury and rho = density of water) by
