Answer:

l = gt²/(2π)²

Step-by-step explanation:

if  T = 2π√l/g

squaring both sides

(T)² = (2π)² × (√l/g)²

T² =4π² × l/g

T² = 4π²l/g

using cross multiplication techniqes

gT² =  4π²l

divede both sides by " 4π²"

gT²/4π² =4π²l/4π²

gT²/4π² =l

l = gT²/(2π)²

that is the final answer.

Answer:

I = (Tg/2π)²

Step-by-step explanation:

T = 2π√l/g

Cross multiply

Tg = 2π√l

Divide both sides by 2π

Tg/2π = √l

Square both sides

I = (Tg/2π)²
