Calculate theoretical value of time period for any length what is the percent error from the experimental to the theoretical period for the mass used? (report below, label by the mass used, and use the theoretical value as the "accepted value"). pick 2 points on your best fit line, and find the slope. what should this slope be? (hint, look at equation (5) and find an expression for l as a function of t°).
