Question

What is the period and frequency of a 10-pound weight oscillating (as a pendulum) on a 5-meter-long rope?

Answer 1

use the formula T = 2*pi*sqrt(L/g)

make sure you use SI units.

Answer 2

I got frequency: 2pi/√ 2
Period: √2/2pi

Answer 3

T is period so you have frequency and period backwards
