Three students, Tom, Sally and Kevin, did an experiment where the accepted size of nano-particles of calcium-tin-oxide is 105.0 nm. Their findings are given in the table below. Whose measurement is most precise, and whose is most accurate? Note that measurement is done in nanometers (nm). Kevin (nm) Sally (nm) 107.0 Trial No. Tom (nm) 1. 103.7 107.7 2. 105.6 101.1 107.5 3. 106.9 105.4 107.9 Mean 105.4 104.5 107.7 None of the given options Tom's measurement is most precise, and Kelly's measurement is most accurate. Sally's measurement is most precise, and Kelly's measurement is most accurate. Kevin's measurement is most precise, and Tom's measurement is most accurate

Question 12 An optical track for a new physics experiment was measured using a high tech laser. It was found to be 2.71828 m long with an uncertainty of 0.05432 m. Find the relative uncertainty for this measurement: 0.02 (0.018) 0.02 m O (2.72 + 0.05) m O (2.71828 + 0.05432) m O 0.019

3. Using the instruments from problem 1, you can take the following measurements for the distance a toy car travels in 10 seconds during each of  5 trials: 157 cm, 175 cm, 162 cm, 168 cm, 187 cm. What are the percent uncertainties of the distance and time measurements? Which of the two measurements is the most uncertain? 4. Calculate the average speed of the toy car. Use the weakest link rule to determine the uncertainty in the speed.
