Question1
A truck is carrying a steel beam of length 17.0 m on a freeway. An accident causes a beam to be dumped off the truck and slide horizontally next to the ground at a speed of 27.0 m/s. velocity of the center of mass of the beam is northward while the length of the beam maintains an east–west orientation. The vertical component of Earth's magnetic field at this location has a magnitude of 44.0 µT. What is a magnitude of the induced emf between the ends of the beam?
Question2
