(4) In an experiment of a simple pendulum, measurements show that the pendulum has length L = 0.397 ± 0.006 m, mass M = 0.3172 ± 0.0002 kg, and period Texp = 1.274 ± 0.005 s. Take g = 9.8 m/s². i. Use the measured length L to predict the theoretical pendulum period Ttheo with a range of error (use the error propagation method you learned in Lab 1). ii. Compute the percentage difference (as defined in Lab 1) between the measured value Texp and the predicted value theo
