Analysis Plot a graph of log T against log l. This should produce a straight line of slope n and y intercept equal to log k. Explain why this is so. Note that you need not show log T = 0 but you must include log 1 = 0 in order to obtain the y intercept. From the graph, n= log k = k= Hence from equation (A3.2) g=
From the graph calculate the length of a pendulum beating seconds (i.e. one with a period of 2 s). Length = m. Conclusions The actual value of g in Johannesburg is 9,79 m.s-2. Compare this with your measured value. What do you conclude? From equation (A.31) and (A3.2) T = 2π in vg (A3.3) Use the method of dimensional analysis* to find the value of n. Compare this with your value of n.
