KaylaN is on a distinguished road
Exclamation Calculate g and its uncertianty??? please help

1. In an actual pendulum experiment, similar to the one described in example 3, an experimenter typically
measures the period T for various lengths L and computes g for each. The following table gives a set of data
for 2 separate pendulum experiments. The uncertainties in measuring length and time are ± 0.5cm and
± 0.05s.
Table
L(cm)--- T(s) ---g(cm/s2) ---dl/l ----dT/T -----dg/g -----Answer for g
93.8 ---1.944 ---980. ------0.0053 ---0.026 ---0.052 ----9.8 ± 0.5 m/s2
80.3 ---1.761
Calculate g and its uncertainty *g for the second set of data displayed.

Please state your difficulty or attempt for this question so that we can guide you instead of giving you the full soulution. For this case, recall the equation for the period of pendulum.
