The two pulses reflect off the boundaries of the string, and at some later time, they pass through the middle of the string and interfere. below are six different sequences of snapshots taken as the two pulses meet in the middle of the string. time increases from top to bottom in each sequence. which sequence correctly represents the displacement of the string as the pulses interfere?

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
