The following table gives values of the Lenght or extension in centimeter of a string during harmonic motion a simple experiment to determine acceleration due to gravity. The period for 20 oscillations are obtained as shown in the table below e/cm T/s 2.0 0.35 3.9 0.44 6.0 0.53 7.6 0.58 19.8. 66 11.0 0.68 vertical
