Answer:
3.24 feet.
Step-by-step explanation:
We have been given that length of time ( T ) in seconds it takes the pendulum of a clock to swing through one complete cycle is given by the formula , where, L is the length, in feet, of the pendulum.
To find the length of pendulum, we will substitute in the given formula as:
Divide both sides by 2:
Substitute :
Multiply both sides by :
Square both sides:
Switch sides:
Therefore, the length of the pendulum is approximately 3.24 feet.
