Question

calculating errors (opus) suppose your bathroom scale reads your mass as 65 kg with a 3% uncertainty. what is the uncertainty in your mass (in kilograms)? -> measured to be 130 + 5 beats/min. what is the percent uncertainty in this measure-

Explanation:

Step1: Identify the formula

To find the uncertainty in a value, we use the formula: Uncertainty = Percentage uncertainty×Measured value.

Step2: Substitute values

The measured mass is $m = 65$ kg and the percentage uncertainty is $3\%=0.03$. So, the uncertainty $\Delta m=0.03\times65$.

Step3: Calculate

$\Delta m = 1.95$ kg.

Answer:

$1.95$ kg
