In a capacitor in an AC circuit, the voltage:
 a. lags the current by 90.
  b. may lead or lag the current depending on the frequency.
  c. leads the current by 90.
  d. is in phase with 70.7 of the current.

Question 2

I stretch a rubber band and plunk it to make it vibrate in its fundamental frequency. I then stretch it to twice its length and make it vibrate in the fundamental frequency once again. This rubber band is made so that doubling its length doubles the tension and reduces the mass per unit length by a factor of 2 . The new frequency will be related to the old by a factor of:
 a. 4.0.
  c. 1.4.
  b. 2.0.
  d. 1.0.
