Question

Suppose that it takes a simple pendulum 1.2 seconds to swing from its leftmost point to its rightmost point. What is the period of the pendulum?

a) 0.6 s
b) 1.2 s
c) 2.4 s
d) 3.6 s

Answer 1

The period of a pendulum is determined by its length and can be calculated using the formula T = 2π√(L/g). Given the information that it takes 1.2 seconds for the pendulum to swing from left to right, the period of the pendulum is 1.2 seconds.

Step-by-step explanation:

The period of a pendulum is the time it takes for the pendulum to complete one full swing back and forth. It is determined by the length of the pendulum. The formula to calculate the period of a pendulum is T = 2π√(L/g), where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity.

Given that it takes a simple pendulum 1.2 seconds to swing from its leftmost point to its rightmost point, we can calculate the period by rearranging the formula: T = 2π√(L/g) is equal to 1.2 seconds. Since the period is 1.2 seconds and we're looking for the period, the correct answer is (b) 1.2 s.
