What is the period of the pendulum? 1) A bob of mass 120 g is hanging from a string of length 25 cm. What is the period of the pendulum? 2) If you wanted to double period of the pendulum, what should you do? A) Quadruple the length of the string. B) Double the length of the string. C) Double the mass. D) Halve the length of the string. 3)... show more 1) A bob of mass 120 g is hanging from a string of length 25 cm.
