Suppose that a grandfather clock is calibrated correctly at sea level and is then brought up to the top of a tall mountain. What would need to be done to calibrate the clock at the top of the mountain?<--EndFragment-->
  1.Nothing, it should work fine since it was already calibrated at sea level.
  2.The bob of the pendulum should be slid slightly down the rod.
  3.The bob of the pendulum should be slid slightly up the rod.
  4.It cannot be calibrated at the top of the mountain.

Question 2

A mass, m, is hung from a spring that has a spring constant, k, and the system is set into oscillation. The period of the oscillation is measured and recorded as T. If the mass is doubled and the spring is replaced by a less-stiff one that has half the spring constant, k/2, what will happen to the subsequent period of oscillation of the new spring-mass combination?
  1.It will remain the same.
  2.It will quadruple.
  3.It will double.
  4.It will halve.
