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?
In Fig. , a rectangular block floats in a liquid . A block of mass m = 0.500 kg and density rho = 700 kg//m^(3) floats face down in a liquid of density rho_(f) = 1200 kg//m^(3) . What are the magnitude of the buoyant force on the block from the liquid , the weight of the liquid displaced by the block (liquid that would be in the space now occupied by the block ) , and the mass of that displaced liquid ? What fraction of the block's volume is submerged ? What fraction of its height is submerged ?
A wooden block of density 860 kg//m^(3) at 0^(@)C is floating on bezene liquid of density 900 kg/m^(3) at 0^(@)C . The temperature at which the block just submerge in benzene is [gamma_(wo od)=8xx10^(-5//@)c, gamma_("benzene")=12xx10^(-4//@)c]
A block of density 2000kg//m^3 and mass 10kg is suspended by a spring stiffness 100N//m . The other end of the spring is attached to a fixed support. The block is completely submerged in a liquid of density 1000kg//m^3 . If the block is in equilibrium position.
