Q1. The current in a coil changes from 3.80 A to 1.90 A in the same direction in 0.510 s. If the average emf induced in the coil is 14.0 mV, what is the inductance of the coil?
Q2. A diatomic gas molecule has a mass of 2.01 x 10-26 kg and a rotational inertia of 3.37 x 10-46 kg•m2 about an axis through the center of the line joining the atoms and perpendicular to that line. Assume the center of mass of the molecule has a translational speed of 677 m/s and the molecule has a rotational kinetic energy that is of the translational kinetic energy of its center of mass. What then is molecule's angular speed about the center of mass?
