An experimental apparatus has two parallel horizontal metal rails separated by 1.0 m. A 2.0-? resistor is connected from the left end of one rail to the left end of the other. A metal axle with metal wheels is pulled toward the right along the rails at a speed of 20 m/s. Earth’s uniform 5.0 x 10-5-T field points down at an angle of 53° below the horizontal. Make a list of the physical quantities you can determine using this information and determine two of them.
