Apiston-cylinder device initially contains 1.2 m³ of saturated water vapor at 600 kpa. at this state, the piston is resting on a set of stops, and the mass of the piston is such that a pressure of 1000 kpa is required to move it. heat is now slowly transferred to the steam until the volume doubles. show the process on t-v and p-v diagrams with respect to saturation lines and determine (a) the final temperature, (b) the work done dur

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
