Answer: 31.42 seconds
Step-by-step explanation:
Given that:
Time taken (T) for a pendulum to complete a full swing or cycle is represented by the equation:
T = 2 Ļ ā(L/32)
T = time taken to complete a full swing in Seconds
L = Length of the pendulum measured in feet
If length (L) of the pendulum = 8 feet
Time taken (T) =?
Inputting our values :
T = 2 Ļ ā(8/32)
T = 2 Ļ ā(1/4)
T = 2 Ļ 0.5
T = 10 Ļ
T = 10 Ć 3.142 = 31.42seconds
