A data is collected for a simple pendulum by taking the time

A data is collected for a simple pendulum by taking the time for 10 oscillations, given by 1/ cm t/s 90.0 18.9 + 0.1 80.0 17.9 + 0.1 70.0 16.7 + 0.1 60.0 15.5 0.1 50.0 14.1 + 0.1 40.0 12.6 + 0.1 Calculate and record values of Tand T2 Include the absolute uncertainties in T2. Plot a graph of T2/ s? against l/cm. Include error bars for T2. Draw the straight line of best fit and a worst acceptable straight line on your graph. Both lines should be clearly labelled. Determine the gradient of the line of best fit. Include the uncertainty in your answer.
