The coil in an ac generator consists of 21 turns of wire, each of area a = 0.12 m2, and the total resistance of the wire is 24 ohms. the coil rotates in a 0.5 tesla magnetic field at a constant frequency of 135 hz. find the maximum induced emf in the coil (in volts).

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.
