Question

Problem 12.7In a laboratory experiment, a muon is observed to travel 800 m before
disintegrating. A graduate student looks up the lifetime of a muon (2 × 10-6 s) and
concludes that its speed was
800 m
4 x 108 m/s.
2 x 10-6s

Christian Huygens in the 1600’s invented the first clock which was small enough to fit in an ordinary room but much more accurate than the large tower clocks of his day. What was his big idea? Why does it work well on land but not at sea? (Ships would have to wait many years for an accurate on-board timepiece).

1. Two atomic clocks are synchronized. One is placed on a satellite, which orbits around the earth at high speed for a whole year. The other is placed in a lab and remains at rest, with respect to the earth. You may assume that both clocks can measure time accurately to many significant digits. a. Will the two clocks still be synchronized after one year? Explain your reasoning. b. Imagine that the speed of light was much slower than its actual value. How would the results of this experiment change if the speed of light was only twice the average speed of the satellite? Explain your reasoning, using a calculation.
Post-Lab Homework Problems. 1. A student is using a track photogate to determine the time it takes her to run 50 meters. She records the following times: Trial Time (seconds) 1 5.420 5.464 3 5.728 4 5.496 5 5.644 6. 5.794 7 5.540 The data she collects has a mean of 5.583714 seconds, with an absolute uncertainty computed to be 0.141074 seconds. Report her 50-meter time as a confidence interval (a) using the mean and the absolute uncertainty given above. Another student measures his 200-meter run time (b) to be 20.7 + 0.3 seconds. Report the relative uncertainty of each student and identify which has the more precise run time.
