A40-w lightbulb connected to a 120-v source experiences a voltage surge that produces 132 v for a moment. by what percentage does its power output increase? assume its resistance does not change. a 40-w lightbulb connected to a 120-v source experiences a voltage surge that produces 132 v for a moment. by what percentage does its power output increase? assume its resistance does not change.

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?
