Liquid of density rho in a container exerts pressure P given by (height of liquid h and area A)

Three liquids of densities rho_1 , rho_2 and rho_3 (with rho_1gtrho_2gtrho_2) having the same value of surface tension T , rise to the same height in three identical capillaries. The angles of contact theta_1 , theta_2 and theta_3 obey

Derive an expression for pressure exerted by liquid column.

Densities of two gases are in the ratio 1:2 and their temperatures are in the ratio 2:1 , then the ratio of their respective pressure is "_____________" .

Two solid spheres(A and B) are made of metals,of different densities p_A and p_B respectively. If their masses are equal, the ratio of their moments of inertia ((I_B)/(I_A)) about their respective diameters is

Equal volume of two immiscible liquids of densities rho and 2rho are filled in a vessel as shown in the figure. Two small holes are punched at depths h//2 and 3h//2 from the surface of lighter liquid. If v_(1) and v_(2) are the velocities of efflux at these two holes, then v_(1)//v_(2) is

A capillary tube of radius r is dipped in a liquid of density rho and surface tension S. if the angle of contanct is theta , the pressure difference between the two surface in the beaker and the capillary ?

A closed organ pipe of length L and an open organ pipe contain gass of densities rho_(1) and rho_(2) , respectively. The compressibility of gass are equal in both the pipes. Both the pipes are vibrating in their first overtone with same frequency . The length of the open orange pipe is

When a capillary tube of radius 'r' is dipped vertically in a liquid of surface tension T, the liquid rises to a height 'h' in the tube above the level outside the tube. If the angle of contact is theta , the density of the liquid is rho , then the pressure difference is.

A spherical solild of volume V is made of a material of density rho_(1) . It is falling through a liquid of density rho_(2)(rho_(2) lt rho_(1)) . Assume that the liquid applies a viscous froce on the ball that is proportional ti the its speed v, i.e., F_(viscous)=-kv^(2)(kgt0) . The terminal speed of the ball is
