This ordain be utilize throughout: The doubtfulness 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 attractive of 5 put down readings. Overview First we shall calculate the snip period T (s) and its uncertainty by calculating the fair age 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 pass on that Comparing with Miss Whatsthefuzz! We not th at; The function y is correspond 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 graphical record of log T (y-axis) against log l, we should get a clean line for which n is the gradient and log k is the y-intercept.

With the economic aid of the error bars, we will also draw lines of maximum and lower limit gradients and from these we shall find the uncertainties in the values of n and k. Sample Calculations only sample calculations have been done for a cantilever distance of 0.9 m. 1. The average time, tave (s) for 20 oscillations is calcul! ated 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: BestEssayCheap.com
