In tests on earth a lunar surface exploration vehicle (mass = 5.45 × 103 kg) achieves a forward acceleration of 0.217 m/s2. To achieve this same acceleration on the moon, the vehicle's engines must produce a drive force of 1.50 × 103 N. What is the magnitude of the frictional force that acts on the vehicle on the moon?

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
