Question

The formula to Calculate time period is given T=No.of oscillation by total time taken

Answer 1

Answer:

With the equation for a period T = 2π (L/g)__-1/2, you can rearrange the equation to obtain L = (T/2_π)2 /g_ and substitute 1 sec for T and 9.8 m/s2 for g to obtain L = 0.0025 m. Keep in mind these equations of simple pendulum theory assume the length of the string is frictionless and massless.
