The electric-power industry is interested in finding a way to store electric energy during times of low demand for use during peak-demand times. one way of achieving this goal is to use large inductors. part a what inductance l would be needed to store energy e=3.0kwh (kilowatt-hours) in a coil carrying current i=300a? view available hint(s) ll l = nothing h provide feedback

When you turn on a battery-operated device, an electrical circuit is

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
