the three ropes in the figure are tied to a small, very light ring. two of the ropes are anchored to the walls at right angles, and the third rope pulls as shown. what are t1 and t2, the magnitudes of the tension forces in the first two ropes?

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

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
