If the diameter of a radar dish is doubled, what happens to its resolving power, assuming that all other factors remain unchanged?
 
  A) The resolving power does not change unless the focal length changes.
  B) The resolving power is reduced to 1/4 of its original value.
  C) The resolving power is reduced to 1/2 of its original value.
  D) The resolving power doubles.
  E) The resolving power quadruples.

Question 2

A wheel of radius R is rolling on a horizontal surface. Its center is moving forward with speed v. A point on the wheel a distance r/3 below the center is moving forward at a speed 2v/3. The wheel is
 
  A)
 
  rolling without slipping.
  B)
 
  not rotating at all.
  C)
 
  made of rubber.
  D)
 
  slipping because its angular speed is too low to be rolling without slipping.
  E)
 
  slipping because its angular speed is too high to be rolling without slipping.
