A120-v rms voltage at 1000 hz is applied to an inductor, a 2.00-μf capacitor and a 100-ω resistor, all in series. if the rms value of the current in this circuit is 0.680 a, what is the inductance of the inductor?

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?
