The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?

To do work, this truck uses energy stored in chemical fuel and an electrical battery. how much total energy does this truck put out?

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
