i am confused.i need help with this experiment.
experiment set up: 1.measure total mass M of the crocodile clip and load.(in gram) 2.measure a length L of the string from the glass tube. 3.hold the tube vertically and whirl the rubber bung around. 4.measure the time t required for the bung to complete 50 revolutions. 5.repeat step 23 using different L. 6.plot t^2 against L. 7.prove how to prove by using Mg=mLω^2 and ω=2∏/T(period)?

Solve your equations for t(L). What is the slope of f(L)=tē(L)?
