If bj > 0 for every j and if p ∞j =1 bj converges then prove that p ∞j=1( bj)2 converges. prove that the assertion is false if the positivity hypothesis is omitted. how about third powers?

Explain vector addition, triangle method and parallelogram method

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
