You are standing on a cliff that is 75 m above the ocean and you see a ship that is 350 m from the bottom of the cliff. Find the angle of depression from you to the ship.

A closed loop conductor with radius 2.0 m is located in a changing magnetic field. If the maximum emf induced in the loop is 2.

A 45-mH ideal inductor is connected in series with a 60-Ω resistor through an ideal 15-V DC power supply and an open switch. If the switch is closed at time t = 0 s, what is the current 7.0 ms later?
