A hollow spere, radius 0.20m is attached to the end of a 0.80m long string, hung vertically and used as a simple pendulum.
The sphere is filled with water. Suppose there is a small hole in the bottom of the sphere. As the filled sphere swings back and forth, water slowly drains.
Question: If this has no effect on the period explain why. If it does affect the period describe how the period changes and why.
