An inductor is connected to an AC source. If the inductance of the inductor is 0.528 H and the output voltage of the source is given by Δv = (120 V)sin[(21.0 s−1)t], determine the following.
(a) the frequency of the source (in Hz)
(b) the rms voltage across the inductor (in V)
(c) the inductive reactance of the circuit (in Ω)
(d) the rms current in the inductor (in A)
(e) the maximum current in the inductor (in A)

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
