How would you solve this without knowing any variables?

The period ofa pendulum is given by the equation shown below, where L is the length of the pendulum in feet, 9! is the acceleration due to gravity, and Tis the time in seconds. L T: 2117.1} 9 The pendulum has been subjected to an increase in temperature such that the length has increased by 3% (a) Find the approximate percent change in the period. |:| % (b) Using the result in part (a), nd the approximate error in this pendulum clock in 1 day.
