# College Physics Problem 1.14

## Solution:

The percent uncertainty can be calculated as

$\displaystyle \%\:uncertainty\:=\frac{\delta _A}{A}\times 100\%$

$\displaystyle \%\:uncertainty\:=\frac{5\:beats/min}{130\:beats/min}\times 100\%$

$\displaystyle \%\:uncertainty\:=3.85\:\%$

Therefore, the percent uncertainty is 3.85%.
