Chapter 1, Problem 34PQ
In a laboratory, a researcher fails to start a stopwatch at the beginning of an experiment. Instead he starts it a little late and finds that the time is between 17.89 s and 17.92 s. What should he report for the measurement of the time?

A high school track coach has just purchased a new stopwatch. The stopwatch manual states that the stopwatch has an uncertainty of ±0.05 s . Runners on the track coach's team regularly clock 100 m sprints of 11.49 s to 15.01 s . At the school'slast track meet, the first-place sprinter came in at 12.04 s and the second-place sprinter came in at 12.07 s . Will thecoach's new stopwatch be helpful in timing the sprint team? Why or why not?
Until 1883, every city and town in the United States kept its own local time. Today, travelers reset their watches only when the time change equals 1.0 h. How far, on average, must you travel in
degrees of longitude between the time zone boundaries at which your watch must be reset by 1.0 h? (Hint: The Earth rotates 360° in about 24 h.)
