1. Simple pendulum provided by the lab, the pendulum length is measured by metric ruler with a value of 700.3 mm, the diameter of the bod D is measured by Vernier caliper with a value of 20.24 mm. the minimum division of the metric ruler is 1mm, the minimum division of the Vernier caliper is 0.02mm, the minimum division of the stopwatch is 0.01s. The reaction time of the pressing the stopwatch is 0.1s according to statistical analysis, the time of 20 the period (N=20) measured by stopwatch is shown as following Time of measurement 1 2 Times (s) 4 5 33.55 33.86 33.91 34.10 33.56 3 (1) Please find the value of L (length of the pendulum) and T, with the uncertainty (2) Please find the gravitation acceleration g with the uncertainty, using T 2n/g %3D
