To solve the problem, we need to determine the precision and accuracy of the pendulum's oscillation time measurements. Let's break it down step by step. ### Step 1: Identify the Measurements We have three measurements of time for 20 oscillations of a pendulum: - \( t_1 = 39.6 \, \text{s} \) - \( t_2 = 39.9 \, \text{s} \) - \( t_3 = 39.5 \, \text{s} \) ...
