Poppy · Answer 1

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.

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
