A syringe is filled with water. Its volume is V_(0)=40cm^(2) and cross section of its interior is A =8cm^(2) . The syrings is held vertically such that its nozzle is at the top, and its piston is pushed up with constant speed. Mass of the piston is M=50 g and the water is ejected at a speed of u_(0)=2m//s . cross section of the stream of water at the nozzle is a=2mm^(2) . Neglect friction and take the density of water to be rho=10^(3)kg//m^(3) (a) Find the speed of the piston (b) Find the total work done by the external agent in emptying the syringe.

Why does the liquid rise in a syringe when its piston is pulled up?
