Question

Suppose that your bathroom scale reads your mass as 65 kg with a 3% uncertainty. What is the uncertainty in your mass (in kilograms)?

a) 1.95 kg
b) 1.95 g
c) 1.95 x 10^2 kg
d) 1.95 x 10^3 kg

Answer 1

The uncertainty in the mass is 1.95 kg.

Step-by-step explanation:

To calculate the uncertainty in your mass, you need to determine 3% of your mass. The uncertainty is calculated by multiplying your mass by 0.03 (3%).

Uncertainty = 65 kg * 0.03 = 1.95 kg

Therefore, the uncertainty in your mass is 1.95 kg.
