			8(pi)
			32(pi)
			4(pi)

			0.99 m
			3.1 m
			6.2 m
5	The length of the pendulum arm on a clock is 55.0 cm. How long does it take for the pendulum arm to swing from the left to the right once? (The clock is near the surface of the Earth.)
			14.9 m
			7.44 m
			1.49 m
			0.744 m
6	By what factor is a pendulum's period of motion changed if the length of the pendulum's arm is 4 times longer?
			The period of motion is not changed from the original.
			2 times longer
			(1/2) times longer
			4 times longer
7	By what factor is a pendulum's period of motion changed if the mass on the end of the pendulum is 9 times more massive than originally?
			The period of motion is not changed from the original.
			3
			9
			81
8	A pendulum is moved from the Earth to asteroid, "X." By along the journey to asteroid, "X," the pendulum's arm was changed by a factor of (1/3) while the mass on the end was doubled. When the pendulum was set in motion on asteroid, "X," its period of motion was 3 times longer than on the Earth. By what factor is the has the acceleration due to gravity changed?
			The period of motion is not changed from the original.
			(1/9) times that of the original.
			(2/9) times that of the original.
			3 times that of the original.
			1/27 times that of the original.
