Why are satellites placed into orbit at least 150 km above Earth's surface?

to avoid air resistance

to match Earth's curvature

to create inertia

to increase friction

In an electromagnetics lab, you are studying two coils which have a mutual inductance of M=300 mH. Suppose that the current in the 1st coil increased linearly from 2.8 A to 10 A in a span of 300 ms and that the 2nd coil has a resistance of R=0.

A ball is dropped from an initial height and allowed to bounce repeatedly. On the first bounce (one up-and-down motion), the ball reaches a height of 32 inches. On each successive bounce, the ball reaches 75% of its previous height.

An inductor with an inductance of 3.50 H and a resistance of 8.00 Ω is connected to the terminals of a battery with an emf of 4.00 V and negligible internal resistance.
