Table 1. Period T of the pendulum of mass m (five washers) as a function of the length L and VL Period T in seconds Length L in meters VL in Vmeters 9.5/ 10 = 0.95 0.20 12.82/ 10 0.45 1. 28 0.40 0.63 15. 20/ 10 1. 52 0.60 0.77 17. 69/ 10 1. 77 0.80 0.89 20. 33/10 2. 03 1.00 1.00 A. 1. Plot in Excel (https://www.youtube.com/watch?v=MfEAEmdFOBo) the pendulum period in seconds (y-axis) vs. the square root of the length in meters (units in vmeters) on the x-axis. The produced graph will show a linear relation (straight line). A.2. The period of a pendulum for small-angle values (a s 10) is given by the following equation T = 2n VI Vg (1 ) A.3. The term 27 / represents the slope of the linear graph. Use the slope value to calculate the value of the gravity g. Rename this value as gExp (experimental gravity) and compare it with the value gEarth = 9.81 m/s2. Use the following formula: Ag(%) = 9Exp - Earth x 100 21-98 - 63 (2) Earth 9.0
