To allow a car to slow down or stop, hydraulic brakes transmit forces from a master cylinder to the brake pads through a fluid. Imagine this system as a tube filled with an incompressible fluid and a piston on each end. A force of is applied to a piston in diameter on one end of the tube. a. What is the magnitude of the force that is exerted on the piston in diameter on the other side? b. If the piston is displaced by 1.00cm by how much is the piston displaced?
