A gas at constant pressure of 4.0X10Pa is cooled so that its Volume decreases from 1.6m² to 1.2m² What Work is performed by the gas?

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is
