Question

A student made the following nine measurements of the time for a ball to roll down an inclined track: t = 2,47 s, 2.48 s, 2.37 s, 2.51 s, 2.46 s, 2.39 s, 2.38 s, 2.49 a. If the stopwatch can measure to the nearest 0.01 s, what is the instrumental uncertainty, delta_max a. 0.01 s b. 0.1 s c. 0.0 s d. 2.44 s What is a reasonable estimate of the sample uncertainty, delta_samp? a. 0.01 s b. 0.1 s c. 0.05 s d. 0.06 s e. 0.07 s f. Answers c, d, and e are all reasonable estimates What is a reasonable value for the overall uncertainty of the measurement, delta_t? To determine this, consider both the instrumental and sample uncertainties and choose the larger value. Remember there are often several different reasonable estimates of the sample uncertainty. a. 0.1s b. 0.01s c. 2.44 s d. None of these. What is the "best estimate" of the true value of the measurement, t_best? In most cases, this is the average of the measured values. Remember, this value should be rounded to the same decimal place as the uncertainty, delta_t. a. 2.37 s b. 2.44 s c. 2.51s d. 2.4 s

Explanation / Answer

5]b, because the measurements are taken till tenth place.

6] b, because we will get average as 2.44444 and rounding off to two decimal place we will get the answer.
