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

A fire truck travels at a speed of 90.0 km/h with its siren emitting a frequency of 500Hz. What is a frequency heard by a passenger in a car travelling at 65 km/h in opposite lane to fire truck, approaching it and moving away from it.
