(remember l should be in meters) 6.Shorten the string by to a length of 90 cm and repeat stairs 2-5 7. On graph paper, plot of land a graph of T2 vs l. This graph should be a genuine line (why?), so draw a line of outfox fit. 8. Calculate your average % erroneous belief, and explain it in your conclusion. It should be rattling low for this lab!
