    1. Assume an experiment is performed with an N-number of trials. Each trial measures the same thing with exactly the same procedure and measuring tools. The thing which we measured is the "time" of a process, the trial number N is 3, the time is: "5.0s, 6.0s, 5.5s". a.Then the "best" value (arithmetic average) of this measurement of time is s (keep 2 significant figures); b. the standard deviation is s (keep 1 significant figures); c. the random uncertainty associated...

    An object is released from rest and falls in free fall motion. The speed v of the object after it has fallen a distance y is given by v2 = 2gy. In an experiment, v and y are measured and the measured values are used to calculate g. If the percent uncertainty in the measured value of v is 4.78% and the percent uncertainty in the measured value of y is 5.00%, what is the percent uncertainty in the calculated...
