Aspaceship of mass 8600 kg is returning to earth with its engine turned off. consider only the gravitational field of earth. let r be the distance from the center of earth. in moving from position r1 = 7300 km to position r1 = 6700 km the kinetic energy of the spaceship increases by

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
