The relative density of lead is 11.3 . What is its density in CGS and SI ?

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

A solid body floats in a liquid at 50^(@)C , being completely submerged in it. What fraction of the volume of the body would be submerged when it is cooled to 0^(@)C ? The coefficient of volume expansion for the solid is 0.3 times 10^(-5)K^(-1) and that of the liquid is 8.0 times 10^(-5)K^(-1) .

A solid spherical ball having density d and volume v floats on the interface of two immicible liquids. The density of the upper liquid is d_1 and that of d_2 for lower one. What fraction of the volume of the ball will be in upper and lower liquids, if d_1 < d < d_2 .

When a body is put into three liquids in succession, it floats with 1/2,1/3and1/4 of its volume immersed in the three liquids respectively. If the body is put into a mixture of these liquids, mixed in equal volumes, what fraction of its volume will remain under the liquid?

A body floats in water with 40% of its volume outside water. When the same body floats in oil, 60% of its volume remains outside oil. The relative density of the oil is
