Hello, I did the graph for the first set of data, I'm not sure how to find the missing data for the table. Can I have help please, how do I get answers for period ^2 (s2) as shown below.

Ength Vs Period to Period ( $ ) 25 25 45 35 15 75 85 95 105 15 125 PROCEDURE The data in the table below shows how the period of a pendulum depends upon the length of the pendulum. The period is the time required for the pendulum to complete one full cycle, over and back. You may prefer to collect your own data (either in lab, in the Physics Resource Lab, or at home) by setting the length of the pendulum at its various values and measuring the period, which results. Period of a pendulum as a function of pendulum length Length Period Period (cm) (s) (52) 0.45 10 0.65 15 0.75 20 0.90 30 1.10 40 1.25 60 1.55 80 1.80 100 2.00 120 2.20 1 . Prepare a graph of the original data, plotting the length on the horizontal axis and the period on the vertical axis. Choose scales for each axis that are convenient and which use most of the sheet of graph paper. 2. Label your graph with an appropriate title, and label each axis with the name of the quantity and the units. 3. Use a sharp pencil to plot each data point as an X or a dot with a small circle around it. 4. Draw either a single straight line or a smooth curve to represent the data. The line or curve does not need to pass through every point, but should represent the general pattern shown by the data. 14
