A ceiling fan draws a current of 0.625 A and has a voltage of 120 V. The resistance of the ceiling fan, to the nearest whole number, is Ω.

A copper wire has a circular cross section with a radius of 1.25 mm. If the wire carries a current of 3.70 A, find the drift speed in mm/s of the electrons in this wire. (Note: the density of charge carriers (electrons) in a copper wire is n = 8.

Brenda is standing on the beach; the sea is choppy. she observes that the crests of distant waves appear not only smaller, but also closer together than do the crests of waves nearer the beach. this example illustrates a depth cue known as:
