A circular loop of radius 1.79 m is mounted on top of a truck. Initially the truck is at rest oriented so that a vector normal to the loop points north. At this location, the Earth’s magnetic field has a magnitude of 49.6 μT and a direction of due north, 63° below the horizontal.

Over the course of 9.0 seconds, the truck accelerates north, so that at the end of the time interval, the truck is moving at 14.0 m/s north. Find the magnitude of the average induced emf in the loop during this time interval and the direction of the induced current, as viewed from the south.

Over the course of the next 5.0 seconds, the truck turns, so that at the end of the time interval, the truck is moving at 14.0 m/s east. Find the magnitude of the average induced emf in the loop during this time interval and the direction of the induced current, as viewed from the east.

A loop has a radius of 15 centimeters and it is initially in the plane of your screen. A constant magnetic field is pointing out of the screen and has a value of 1T. The loop then rotates by 45º along a vertical axis (so it's partially sticking out of your screen). It takes 4.8 seconds to rotate. Determine the electromotive force (the voltage) that will be generated in the process (express your answer in mV)
