Re: lab report #1 part b
Question 7 is asking for the formula you use to find the error of L. It is given by Equation 5'' in the Error and Uncertainty. Through some algebra we can find it to suit our needs and we get ΔL_{Avg}*√(N1). Just substitute the symbols with the wording they give you.
Question 11 for the first half using algebra rewrite the formula to solve for L. k will be the same formula for L except you do not need T^{2}. Your k value is your slope and can actually be inserted into a y=mx+b formula.
Question 14 you obtain g from the Question 11. Again use algebra to find it, this one is a bit simpler. For the Δg it is the same formula except you need to multiply Δk instead of k.
Try going on with that information, think it out, watch your math and see how well you do.
