This ordain be utilize throughout: The dubiousness of the digital stopwatch used is its smallest reading. This is ± 0.01 s. However the uncertainty used in the calculations shall be the residual effect found from the becoming of 5 put down readings. Overview First we shall calculate the clock fourth dimension period T (s) and its uncertainty by calculating the amount time for 20 oscillations and split by 20. The same shall be done for the uncertainty in time for 20 oscillations. let Then by victorious the logarithm of both sides we playact that Comparing with Miss Whatsthefuzz! We not that; The function y is stand for by log T and x is represented by log l. We leave because calculate the determine of log T and log l and their uncertainties respectively. By drawing a represent of log T (y-axis) against log l, we should get a directly line for which n is the gradient and log k is the y-intercept.

With the care of the error bars, we will also draw lines of maximum and token(prenominal) gradients and from these we shall find the uncertainties in the values of n and k. Sample Calculations all told sample calculations have been done for a cantilever aloofness of 0.9 m. 1. The average time, tave (s) for 20 oscil! lations is calculated by summing all the values collected and dividing by 5. i.e; 2. The uncertainty in the average time, tave, is half the difference in the midst of the highest and the lowest of the 5time-readings. i.e; 3. The period of oscillation, T (s) is the a twentieth of the average time. i.e; 4. The uncertainty in the time period, T, is one-twentieth of the...If you want to get a full essay, order it on our website: OrderCustomPaper.com
