Question

A pendulum of length 80cm completes one oscillation in how much seconds

Answer 1

Answer:12.56√2second

Explanation:

We know that in a pendulum t=2π√l/g

Therefore,

We take ,g=10m/s^2

π=3.14

And the length(l) is given 80cm

.

. . T = 2π√l/g

T=2*3.14√80/10

T=6.18*√8

T=6.18*2√2

T=12.56√2

Hence the answer is 12.56√2 second
