7th form nz physics, given the aim of finding the relationship between period of a 'swinging log' and the length of the sespention rope. i've done the experiment and got my straight line using a log graph but im not sure how to forulate my equation to compare to the theoretical one... ive tried acouple of times but the answers are way different can anyone give me some steps to follow? the theoretical equation is
T= \frac{2pei}{\sqrt{3g}}x\sqrt{L}
i have found that n is 0.65
and k is 1.26 what next??
