Question

Calculate the length of seconds pendulum at a place where acceleration due to gravity is 9.8 and pi=3.14

Answer 1

Answer:

The answer is "0.994m"

Explanation:

Given data:

The time period for seconds pendulum is "T"=2 seconds

g=9.8m/s²

Formula to calculate length:

T=2π√L/g

L=gT²/4π²

=9.8x2²/ 4 x (3.14)²

=0.994 m

Thus, the length of a seconds pendulum is 0.994m which is approximately equal to 1m.  Length "L" = 1m .
