A cylinderical jar of cross-sectional area of 50 cm^(2) is filled with water to a height of 20cm . It carries a tight fitting piston of negligible mass. Calculate the pressure at the bottom of the jar when a mass of 1 kg is placed on the piston . Ignore atmospheric pressure.

A cylindrical tube of cross sectional area 20cm^(2) is filled with water to a height of 10cm. The tube carries a tight fitting piston of negligible mass. What will be the pressure exerted at the bottom of the tube when a mass of 2 kg placed on the piston? Atmospheric pressure can be ignored.

A rigid cylindrical container having a cross sectional area of 0.2 m^(2) is filled with water up to a height of 5.0 m . There is a piston of negligible mass over the water. Piston can slide inside the container without friction. When a weight of 2000 kg is placed over the piston, it moves down by 0.25 mm compressing the water. rho= Density of water = 10^(3) kg//m^(2), P_(atm)= Atmospheric pressure =10^(5) N//m^(2) and g=10 m//s^(2) . With this information calculate the speed of sound in water.

A long cylindrical tank of cross-sectional area 0.5m^(2) is filled with water. It has a small hole at a height 50cm from the bottom. A movable piston of cross-sectional area almost equal to 0.5m^(2) is fitted on the top of the tank such that it can slide in the tank freely. A load of 20 kg is applied on the top of the water by piston, as shown in the figure. Calculate the speed of the water jet with which it hits the surface when piston is 1m above the bottom. (Ignore the mass of the piston)

A cyclinderical vessel of cross-sectional area 1000cm^(2) , fitted with a frictonless piston of mass 10kg , and filled with water completely. A small hole of cross-sectional area 10mm^(2) is opened at a point 50cm deep from the lower surface of the piston. The velocity of efflux from the hole will be

A cylindrical tube of uniform cross-sectional area A is fitted with two air tight frictionless pistons. The pistons are connected to each other by a metallic wire. Initially the pressure of the gas is P_0 and temperature is T_0 , atmospheric pressure is also P_0 . Now the temperature of the gas is increased to 2T_0 , the tension in the wire will be
