1.	Two clocks are being tested against a standard clock located in a national laboratory . At 12:00:00 noon by the standard clock, the regarding of the two clocks are : If you are doing an experiment that requires precision time interval measurements, which of the two clocks will you prefer ?
Answer» SOLUTION :The range of variation over the seven DAYS of observations is 162 s for clock 1, and 31s for clock 2. The average reading of clock 1 is much closer to the standard time than the average reading of clock 2. The important point is that a clock.s zero error is not as significant for precision WORK as its variation, because a .zero-error. can always be EASILY corrected . Hence clock 2 is to be preferred to clock 1.
