(a) Find the force P that must be applied to apiston of area 12.10 cm2 to produce sufficient fluidpressure to support a car weighing 11,851 N by means of a column offluid of cross sectional area 250 cm2 as seen in thefigure below.
(b) Find the increase in the car's gravitational potential energywhen it is raised 1.00 m.
(c) How far must the smaller piston move in order for the largerone to move 1.00 m?
(d) Calculate the work done by P in moving thesmaller piston.
Compare your answer with the answer to part b.
