A block of side `0.5m` is `30%` submerged in a liquid of density `1 gm//(c c)`. Then find mass of an object placed on block for complete submergence.

A block of mass 5 kg and volume 0.05"m"^(3) floats in a liquid of density 140 "kg m"^(-3) . The fraction of block inside liquid is

An object of volume V is submerged in a liquid of density rho . It has flat bottom of area A which is at depth of H in the liquid and a dome shaped top find the total force of liquid acting on the top of the object.

A small block of wood of density 0.4xx10^(3)kg//m^(3) is submerged in water at a depth of 2.9m . Find (a) the acceletation of the block towards the surface when the block is released and (b) the time for the block to reach the surface, Ignore viscosity.

(i) A cubical metal block of side 10cm is floating in a vessel contatining mercury. The vesel has a square cross section of side length 15cm. Water is poured into the vessel so that the metal block just gets submerged. Calculate the mass of water that was poured into the vessel. It is given that relative density of the metal and mercury are 7.3 and 13.6 respectively. (ii) In the last question, in place of water if we poured another liquid of relative density 'r' it was found that when the metal block ws just completely submerged it was no longer touching mercury. what is value of r?
