The Formula for this Problem is T= 2ð*radical (L/g). After solving for L, the new for Formula becomes: g(T^2/4ð^2) = L ... Now you Plug in your Numbers. remember you looking for the difference. It should be Something like this: (9.8*(1.08+0.31)^2)/(4ð^2)-(9.8*(1.08)^2)/(4ð^2). the Answer should be 0.190 meter.
