A mass on a string of unknown length oscillates as a pendulum with a period of 4.0 (s). Parts a to d are independent questions, each referring to the initial situation. What is the period if:
a. The mass is doubled? in seconds
b. The string length is doubled? in seconds
c. The string length is halved? in seconds
d. The amplitude is doubled? in seconds
The solution calculates the period of each condition from a-d with step-by-step calculations and all formulas shown.
