A gas is compressed in a piston–cylinder assembly from 푝-= 2 bar to 푝.= 8 bar, 푉.= 0.02 푚:in a process during which the relation between pressure and volume isdefined as푝푉-.;=constant. The mass of the gas is 0.2 kg. The specific internal energy of the gas increases by 50 kJ/kg during the process. Kinetic and potential energy changes are negligible. For the gas as the system, determine the work, in kJ, and the heat transfer, in kJ.

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
