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» <html><body><p></p>Solution :The range of variation over the seven <a href="https://interviewquestions.tuteehub.com/tag/days-944904" style="font-weight:bold;" target="_blank" title="Click to know more about DAYS">DAYS</a> 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 <a href="https://interviewquestions.tuteehub.com/tag/important-1038039" style="font-weight:bold;" target="_blank" title="Click to know more about IMPORTANT">IMPORTANT</a> point is that a clock.s zero error is not as <a href="https://interviewquestions.tuteehub.com/tag/significant-1207363" style="font-weight:bold;" target="_blank" title="Click to know more about SIGNIFICANT">SIGNIFICANT</a> for precision work as its variation, because a .zero-error. can always be easily corrected . <a href="https://interviewquestions.tuteehub.com/tag/hence-484344" style="font-weight:bold;" target="_blank" title="Click to know more about HENCE">HENCE</a> clock 2 is to be preferred to clock 1.</body></html>
