The picture shows a loop of wire rotating in a magnetic field in a generator. determine the direction of the current through the load as the loop rotates from 180 to 270 degrees as shown in the picture. a) from right to left b) from left to right c) there is not enough information to tell which direction the current will be in the circuit.

Adiver in midair has an angular velocity of 6.0 rad/s and a moment of inertia of 1.2 kg·m2. he then pulls is arms and legs into a tuck position and his angular velocity increases to 12 rad/s. the net external torque acting on the diver is zero. what is his moment of inertia in the tuck position?
