A gas is allowed to expand at constant pressure until it reaches its final volume. It is then cooled at constant volume until it reaches its final pressure. The initial state of 1.00 mol of a dilute gas is P1 = 2.94 atm, V1 = 1.01 L, and Eint 1 = 438 J, and its final state is P2 = 2.00 atm, V2 = 3.03 L, and Eint 2 = 964 J.
Calculate the work done by the gas.
Find the heat absorbed by the gas during this process.
A horizontal force of 150 N is used to push a 45.0 kg packing crate a distance of 5.10 m on a rough horizontal surface. If the crate moves at constant speed, find each of the following. (a) the work done by the 150 N force _________J (b) the coeffici..
A worker drops a wrench from the top of a tower 88.00 m tall. With what velocity does the wrench strike the ground? (Suppose the positive direction is upward.)
A uniform rod of length 0.790 m and mass 14.50 kg is balanced on a sharp edge at 0.650 m from the left end. At the left end hangs a mass of 45-kg and the right end hangs an unknown mass so that the whole assembly is in equilibrium.
