Question details

Tyra Matthews: Attempt 1 Question 1 (0.5 points) To answer this question refer to the document Uncertainty Analysis Explained Consider an experiment where a marble is rolling between sensors for a computer controlled timer called a photogate. The sensor measures the time (t) the photogate is blocked as the diameter (d) of the marble passes by. You have measured the following quantities to determine the speed (v) of a marble rolling in front of a photogate. The uncertainty in time is estimated from the spread in values of several trials, and the size of the marble is known with a manufacturer specification on the uncertainty. t 0.024 0.003 d -2.54 0.03 cm Based on the quantities above, what is the absolute uncertainty in the time measurement? (Hint: This is very easy. No calculation is required.) Your Answer: units
