A hydraulic jack is used to lift a car by applying a force of 120 N at the pump piston. If the area of the ram and pump piston are 100 cm2 and 1m2 respectively:

(i)Calculate the force that is applied to the ram.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
