A simple pendulum
Tie a cord at least 2 m long to some object like a stone or a small metal ball. Suspend this in a doorway or from a hook in the ceiling and begin it swinging through a large are. Count the number of swings it makes in 10 seconds and then multiply by 6 to see how more swings it makes per minute.
At 200.0 K, silicon has 1.89 x 10 5 thermally liberated charge carriers/cm 3 . If it is doped with 1 As atom to 3.75 million Si atoms, what is the ratio of doped carriers to t
