The coil is placed in the magnetic field of a horseshoe magnet. the plane of the coil is at right angles to the field. the coil is then removed to a region where b = 0, and using an oscilloscope, the following signal is observed across the ends of the wires of the coil:

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.

Light traveling in a medium with a refractive index 1.19 is incident on a plate of another medium with index of refraction 1.79. at what angle of incidence is the reflected light fully polarized?
