An experimental apparatus has two parallel horizontal metal, Ask an Expert

Academics

An experimental apparatus has two parallel horizontal metal rails separated by 1.0 m. A 4.0 ohm 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 30m/s . Earth's uniform 5.0 A????1 10x5-Tfield points down at an angle of 53 degrees below the horizontal.

A. Determine the average induced emf. Express your answer with two significant figures and include the appropriate units.
