Two wires are hanging horizontally and parallel to one another and they are spaces 5.4 cm apart. The bottom wire carries a current of 2.3 Amps to the right and has a mass per unit length μ = 2.6 × 10 − 4 k g m. How much current must flow through the upper wire and in which direction (right or left) does the current flow in order to have the bottom wire hover (have the magnetic force balance the gravitational force mg)?

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.
