Answer to Problem 50GP

  ±2.54×105%

Explanation of Solution

Given:

Gain or loss of the watch is not more than 8 s in a year.

Formula used:

Uncertainty percentage is,

  %  = amount of uncertainty  maximum value×100%

Calculation:

Convert one year in to seconds

  1year=1×365 ×24×3600 s1year=3.154×107 s

Percent of uncertainty can be calculated as:

  % = ±83.154×107×100= ±2.536×105%%  ±2.54×105%

Conclusion:

Therefore, ±2.54×105% is the percent of uncertainty of the watch.
