Calculate Kinetic Energy The potential energy of a swing is 200 J at its highest point and 50 J at its lowest point. If mechanical
energy is conserved, what is the kinetic energy of the swing at its
lowest point?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

What are the dimensions of the cross section that passes through the points a, f, g, and d?
