(a) Suppose the length of the pendulum changes by L. How will the period change? Express your answer in terms of T and L only.
deltaT = (T/2L)deltaL
(b) If the length of the pendulum increases by 2%, by what percent does the period change?
???
ok so i figured out part a) that was cake...sort of...well not really, anyways i need help on doing part b) thanks
