In a car lift, compressed air exert a force of, F1 on a small piston having a radius of 5.0cm. This pressure is transmitted to a second piston of radius of 15cm. The mass of the car is 1350kg. Acceleration due to gravity g=10s-2 . How high will the car be lifted if 785N force is applied on the smaller piston?

Edward tolman explained the results of his study by theorizing that the rats were learning about the maze during every trial but they a. were agitated because other groups were getting reinforcement b. could not remember how to demonstrate it without reinforcement c. were not motivated to demonstrate it without reinforcement d. seemed to be too lazy to actually work without reinforcement
