Question 2

A toy gyroscope (a.k.
 a. a top) consists of a solid disk with a thin rod projecting perpendicular to the center of the disk. The rod, which serves as the rotational axis for the gyroscope, projects on both sides of the disk. The gyroscope is placed with one end of the axis on the surface of the table, and spun so that the rotation of the disk viewed from above is counterclockwise. Alas, the axis of rotation is not quite perpendicular table surface and so the gyroscope precesses. Viewing from above, with the end of the axis in contact with the table staying in the same spot, in what direction does the other end of the axis of the gyroscope precess?
  a. The precession is clockwise.
  b. The precession is counterclockwise.
  c. In the northern hemisphere the precession is clockwise, but in the southern hemisphere it is counterclockwise.
  d. In the northern hemisphere the precession is counterclockwise, but in the southern hemisphere it is clockwise.
