Determine the change in internal energy of a monatomic ideal gas that expands from an initial volume of 1.53 m3 to a final volume of 2.87 m3. during this process the pressure of the gas remains at a constant value of 1.82 105 pa.

Asun-sized star will spend most of its lifetime as a: white dwarf red giant protostar main-sequence star

In a series circuit the __ is the same at every point

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?
