Question

T= 2 pi , square the (fraction l/g0, this is the formula for the period T of a pendulum of length l. Solve this formula for l

Answer 1

Below

Explanation:

Formula for period of a pendulum

period = T = 2 pi
`√(L/g)` Divide both side of the equation by 2 pi THEN square both sides to get

(T/ (2pi) ) ^2 = L/g now multiply both sides by 'g'

g * ( T / (2 pi) )^2 = L Done.
