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

 a. oscillation
  b. periodicity
  c. resonance
