s: 1. Thomas Jefferson proposed using the length (L) of a simple pendulum whose period (T) was exactly 2 seconds as the definition of a standard meter. What is the length (L) of a 2 sec. pendulum in SI Units? What is the period (Tmoon) of a Jeffersonian pendulum on the surface of the moon? Hint: Assume gmoon = (1/6) gearth, where gearth = 9.80 m/s2, and that the period of a Jeffersonian pendulum on the earth is: Tearth = 2.00 s
