Help with steps would be appreciated!

The purpose of this exploration is to understand the basic motion of the simple pendulum and what factors determine the period of oscillation of a simple pendulum. Use the Pendulum. Lab simulation to find the experimental value of the period of oscillation. Set "gravity" to "Earth", friction to "none". Use the "period timer" tool to measure the period. Adjust the length of the pendulum and the mass of the pendulum as it indicated in the table. Complete eight runs. Run 2 3 4 5 6 7 8 Length, m 0.4 0.6 0.8 1 0.4 0.6 0.8 Mass, kg 0.5 0.5 0.5 0.5 1.5 1.5 1.5 1.5 Period, s measured Period, s theoretical %difference Use equation T = 2n to calculate the theoretical period of oscillation for each run, where "g" is acceleration due to gravity on Earth. Find the % difference for each run. Show your calculations: What happens to the period of a pendulum if its length changes, but the mass stays the same? What happens to the period of the pendulum if its mass changes, but the length stays the same
