Suppose you have a collection of pendullums of different lengths suspended on a string between two pegs as shown in this figure. Two of the pendulums have the same length and resonate with each other. If the mass of the bob of one of the two pendulums in resonance is doubled while the mass of the other remains the same, the two:
 a. will still be in resonance.
  b. will no longer be in resonance.
  c. will resonate at twice the frequency.
  d. will resonate at a frequency that is not double.

Question 2

What do we call the effect of an increase in the amplitude when a periodic force is applied to a system at its natural frequency?
 a. oscillation
  b. periodicity
  c. resonance
  d. vibration
  e. cycle
