How do you find the ratio of the new/ old world periods of a pendulum if the pendulum wee transported from earth to the moon, where the acceleration due to gravity is 1.63m/s^2?
Im not sure if we use 9.8 at all, I think I'm supposed to use T=2 pi sqrtL/g.

You substitute g of moon for g of earth in the equation; Then do the calculation for g of earth; divide the two to find the ratio.
