A heavy-duty shock absorber is compressed 4 cm from its equilibrium position by a mass of 500nbspkg. how much work is required to compress the shock absorber 8 cm from its equilibrium position? (a mass of 500 kg exerts a force (in newtons) of 500g, where galmost equals9.8 m divided by s squared.)

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

This energy transformation diagram represents the energy of a skateboarder moving along a half-pipe. as she skates toward the top of the half-pipe, her original kinetic energy is converted to potential energy and friction. how much of the energy is potential?
