Question

A watch manufacturer claims that its watches gain or lose no more than 10 s in a year. what is the percent uncertainty

Answer 1

Given:

The absolute error is 10 s.

To Find:

The percent uncertainty

Step-by-step explanation:

The percentage error can be calculated as,

`Percentage`
`error = (Absolute Error)/(Expected Value)`

`Percentage`
`error = (10s)/(365*24*60*60s)`

`Percentage`
`error = 3.17*10^{-7%`%

Hence the percentage uncertainty is

`3.17*10^(-7)`%

Final Answer:

The percentage uncertainty is

`3.17*10^(-7)`%
