When a diver gets into a tuck position by pulling in her arms and legs, she increases her angular speed. before she goes into the tuck position, her angular velocity is 5.5 rad/s, and she has a moment of inertia of 1.4 kg m2. once she gets into the tuck position, her angular speed is 14.5 rad/s. determine her moment of inertia, in kg m2, when she is in the tuck position. assume the net torque on her is zero?

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
