Two horizontal metal rails are separated by 1.5 m and connected at their ends by a 3.0-? resistor to form a long, thin U shape. A metal axle with metal wheels on each side rolls along the rails at a speed of 25 m/s. Earth’s u B field has a magnitude of 5.0 x 10-5 T and tilts downward 68° below the horizontal. Make a list of the physical quantities you can determine using this information and determine two of them.
