Two cylinders of different area of cross section are connected to each other with a pipe. The area of cross section of wider cylinder is 800 cm^2 ?. If a mass of 16kg is placed on the massless airtight frictionless piston in the wider cylinder, find the difference in the level of water in the two cylinders

Fig, shows a U-tube of uniform cross-sectional area A accelerated with acceleration a as shown. If d is the seperation between the limbs. Then the difference in the levels of the liquid in the U-tube is

Figure shows a liquid being pushed out of a tube by pressing a piston. The area of cross section of the piston is 1.0 cm^2 and that of the tube at the outlet is 20 mm^2 . If the piston is pushed at a speed of 2cms^-1 . What is the speed of the outgoing liquid?
