A)20 m
B)0.99 m
C)1.2 m
D)1.6 m
E)0.87 m

Question

Quizplus · Accepted Answer

The period of a simple pendulum is given by:

T = 2π√(L/g)

where L is the length of the pendulum and g is the acceleration due to gravity (9.81 m/s²).

Rearranging this equation, we get:

L = (gT²)/(4π²)

Substituting the given values, we get:

L = (9.81 m/s²)(2.0 s)²/(4π²) ≈ 0.99 m

Therefore, the best choice is B.
