When a pressure measuring device is immersed in a liquid, a restoring force of 2 N is exerted by the spring. If the area of cross-section of the pistion is 10 cm^(2) , what pressure does the fluid exert on the piston?

The figure shows a schematic layout of hydraulic jack. The load to be raised weighs 20,000N. The area of cross section of the two pistons are A_(1)=50cm^(2) and A_(2)=10cm^(2) . The force (F) is applied at theend of a ligh lever bar as shown in the figure. Lenghts a and b are 4cm and 36cm respectively. Find the force (F) required to raise the load slowly.

Consider a vertical tube open at both ends. The tube consistss of two parts, each of different cross sections and each part having a piston which can move smoothly in respective tubes. The two piston which can move smoothly in respective tube wire. The piston are joined together by an inextensible wire. The combined mass of the two piston is 5 kg and area of cross section of the upper piston is 10 cm^(2) greater than that of the lower piston. Amount of gas enclosed by the pistons is 1 mol . When the gas is heated slowly, pistons move by 50 cm . Find the rise in the temperature of the gas in the form X//R K , where R is universal gas constant. Use g = 10 m//s^(2) and outside pressure = 10^(5) N//m^(2)) .

For the system shown in the figure the cylinder on the left at L has a mass of 600 kg and a cross sectional area of 800cm^(2) the piston on the right at S has cross sectional area 25cm^(2) and negligible weight if the apparatus is filled with oil (rho=0.75gm//cm^(3)) find thhe force F required to hold the system in equilibrium.
