When a hydrogen atom's electron goes from an energy state of n = 2 to n = 1,
 a. the radius of the electron's orbit is unchanged.
  b. the radius of the electron's orbit is increased.
  c. the radius of the electron's orbit is decreased.
  d. the radius of the electron's orbit is infinite.

Question 2

A coil is wrapped with 300 turns of wire on the perimeter of a circular frame (radius = 8.0 cm). Each turn has the same area, equal to that of the frame. A uniform magnetic field is turned on perpendicular to the plane of the coil. This field changes at a constant rate from 20 to 80 mT in a time of 20 ms. What is the magnitude of the induced emf in the coil at the instant the magnetic field has a magnitude of 50 mT?
 a. 24 V
  b. 18 V
  c. 15 V
  d. 10 V
  e. 30 V
