Question

5. What should you do to the length of the string of a simple pendulum to double its period? 7. The acceleration of gravity gets smaller as you increase your distance from the center of the Earth. For example, if you go to a height that is one earth radius above the surface of the earth the acceleration of gravity is 2.45 m/s² (g/4.0). Is the period of a pendulum longer or shorter? 8.A pendulum makes 42 cycles in 50.0 seconds. a. What is its period? b. What is its frequency?
