Answer :
Final answer:
The uncertainty in a mass of 65 kg with a 3% uncertainty is calculated by multiplying 65 kg by 0.03, resulting in an uncertainty of 1.95 kg.
Explanation:
If your bathroom scale reads your mass as 65 kg with a 3% uncertainty, the uncertainty in your mass can be calculated by multiplying the mass value by the percentage uncertainty. Since 3% of 65 kg is 0.03 × 65 kg, we find the uncertainty in your mass.
To calculate the uncertainty:
- Multiply the mass by the percent uncertainty (expressed as a decimal).
- 65 kg × 0.03 = 1.95 kg
Therefore, the uncertainty in your mass is 1.95 kg.
