###### Problem Details

A mass on a string of unknown length oscillates as a pendulum with a period of 3.5s. Parts a to d are independent questions, each referring to the initial situation. What is the period if:

Part A: the mass is doubled? (s)
Part B: the string length is doubled? (s)
Part C: the string length is halved? (s)
Part D: the amplitude is doubled? (s)
