Statement of a problem № 42539


A “seconds” pendulum has a period of exactly 2.000 s—each one-way swing takes 1.000s. (a) What is the length of a second pendulum in Austin, Texas, where g = 9.793 m/s2? (b) If the pendulum is moved to Paris, where g = 9.809 m/s2, by how many millimeters must we lengthen the pendulum? (c) What would be the length of a seconds pendulum on the Moon, where g = 1.62 m/s2?
