Hello
All square numbers ends with 0,1,4,5,6 or 9 at units place.
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.
1) correct
2) -3
3) 15/7
4) -10
