If the weight of a body in vacuum is w and `w_(1)` and `w_(2)` are weights when it is immersed in a liquid of specific gravity `rho_(1)` and `rho_(2)` respectively, then find the relation among `w,w_(1)and w_(2)`

If the wt. of a body in vacuum is W and W_1 and W_2 are weights when it is immersed in a liquid of specific gravity rho_1 and rho_2 respectively, then prove that W=(W_1rho_2-W_2rho_1)/(rho_2-rho_1)

If W be the weight of a body of density rho in vacuum then its apparent weight in air of density sigma is

If W be the weight of a body of density (rho) in vacuum then ils apparent weight in air of density (sigma) is

The weights of a body in air and water are W and W' respectively. Prove that the apparent weight of the body when immersed in a liquid of density delta will be W''=W-(W-W')delta .

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)

The weight of an object in the coal mine, sea level and at the top of the mountain are W_(1),W_(2) and W_(3) respectively, then

The weight of an object in the coal mine, sea level and at the top of the mountain are W_(1),W_(2) and W_(3) respectively, then

A metallic solid body of weight 'W_(1)' is immersed in a liquid, whose temperature is t_(1)^(@)C . The apparent wight of the body in the given liquid is 'W_(2)' . Then the temperature of that liquid is changed to t_(2)^(@)C , the apparent wight of the body is 'W_(3)' . If the density of this liquid at t_(1)^(@)C" and "t_(2)^(@)C" was "d_(1) and d_(2) , respectively, then find the volume coefficient of the solid body in terms of W_(1),W_(2),W_(3),d_(1),d_(2)" and "t_(1)^(@)C" and t_(2)^(@)C .
