Question

help....i will give medal who ever will show me the solution.

Answer 1

A student conducted an experiment to measure the acceleration due to gravity ,g, of a simple pendulum.
the data are tabulated
length of thread,l/m:0.35 0.65 1.00 1.45 1.95
time for 20
oscillations,t/s: :24.1 32.4 40.1 47.5 56.3
Given that the relation between the periodic time ,T,the length of pendulum,l,and the acceleration due to gravity,g, is\[T=2\pi \sqrt{(l/g)}\] ,find the value of 'g' using a graphical approach.
