4. For different lengths L, measure the time for 10 swings t 10, calculate the period Tet,/10 L (m) vertical axis t10 (s) T (s) T2 ($2) horizontal axis 1.0 20.35 2.035s (2.035)^2=4.14 5. Plot a graph of the T2 vs L using EXEL * Horizontal axis: T2 (s2) and Vertical axis: L(m) *should obtain a straight line - show linear trendline and trendline fit equation * Cut and Paste the graph with properly labelled axis and the equation of the trendline fit : y=ax+b Slope="a" = Calculate the cvalue of g by inserting value of "a" (ie slope) into the equation below: Show calculation g= 4712/slope =
