A body in water weighs three-fourths of its weight in air. Calculate the density of the body in S.I. unit.

0.2 part of the volume of a body floating in a liquid remains exposed to air. In water, 0.1 part of that floating body remains exposed to the outside air. Calculate the density of the liquid.

The relative density of gold is 19.3. if the density of water be 10^(3) kg/ m^(3) , calculate the density of gold in SI unit.

The specific heat of water S.I. unit is.

A body floats with one third of its volume outside water and 3/4 of its volume outside another liquid. Calculate the density of the other liquid.

The density of a body is d and that of air is rho . If the body weighs W in air, show that the actual weight of the body is =W/(1-rho/d)

A body is fully immersed in water. Calculate the change in potential energy of the body, raised to a height h inside the water.

To determine the composition of a bimetallic alloy, a sample is first weighed in air and then in water. These weights are found to be w_1 and w_2 respectively. If the densities of the two constituent metals are rho_1 and rho_2 respectively, then the weight of the first metal in the sample is (where rho_w is the density of water)

A body weighs 100gxxgand40gxxg in air and water respectively. Calculate the weight of the body when immersed in a liquid of specific gravity 0.8.

The weight of a body in air is 100 g and its weight in water is 40 g. Find the volume of the body.
