Question

Answer all questions: 1. Was the experiment accurate in finding the experimental value for the frequency? YES NO State clearly the basis for your answer. 2. Was the experiment of finding the frequency precise? YES NO What would your need to answer this question? Explain your reasoning. 3. Does the value of intercept you found reasonable? YES NO Explain your answer. loheceptiyair订 _o.nouu mete, s/yes 4. Suppose the frequency is f-60 Hz, L is the one you measured, and the string has a linear densit -2.95 x 10 kg/m. What is the tension T, in the string for one loop? Show your work.

Answer 1

1. An experiment is said to be accurate if the experimental findings are very close within the range of experimental error of the theoretical expected values

hence in the experiment as the results were close to the expected results within the scope of experimental error hence the experiment results were accurate

2. An experiment is said to be precise if the standard deviation of the experiment results is very small. For an accurate experiment, the experiment is successful only if the experiment is precise as well otherwise the experiment is said to be correct by chance

hence in the experiment the findings were close to one another hence their common standard deviation was very low and hence the experiment was prcise as well

3. the intercept on y axis is y = 0.32044 m
   the value of this intercept is reasonable and it is the length of the string used

4. suppose
   f = 60 Hz
   mu = 2.95*10^-4 kg/m
   then
   for one loop

   c = 2Lf
   and
   c = sqrt(Ts/mu) = 2Lf
   Ts = 4L^2f^2*mu

   the y intercept is L = 0.32044 m
   so Ts = 0.43619 N
