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?

Air is held within a frictionless piston-cylinder container, which is oriented vertically. the mass of the piston is 0.45 kg and the cross-sectional area is 0.0030 m2. initially (state 1) the pressure of the gas is sufficient to support the weight of the piston as well as the force exerted by the atmospheric pressure ( 101.32 kpa). the volume occupied by the air within the cylinder in state 1 is 1.00 liter. one end of a spring (with spring constant k = 1000 n/m) is attached to the top of the piston, while the other end of the spring is attached to a stage that can move vertically. initially the spring is undeflected and therefore exerts no force. then the stage is then moved quasistatically downward a distance of 10.0 cm, at which point the system reaches state 2. the piston-cylinder is not insulated; rather it remains in diathermal contact with the surroundings, which are at a constant temperature of 300 k. what is the change of pressure within the container?

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called
