Question

The time period, T, of a simple pendulum is directly proportional to the square root of the length, d, of the pendulum.

Answer 1

Step-by-step explanation:

T = k * sqrt(d), where k is a real constant.

When d = 6, T = 5.

k = T / sqrt(d) = 5 / sqrt6.

Therefore when d = 3, T = (5 / sqrt6) * sqrt3 = 3.53.
