Question

What, approximately, is the percent uncertainty for the measurement given as 5.04 m2m2 ?

Answer 1

The percent uncertainty for the given measurement can be calculated using the formula:

% Uncertainty = (Absolute Uncertainty / Measured Value) x 100

For the given measurement, we need to determine the absolute uncertainty. As the value is given with two significant figures, we will assume the uncertainty to be ±0.01 m2.

Therefore, the measured value can be written as 5.04 ± 0.01 m2.% Uncertainty = (0.01 / 5.04) x 100% Uncertainty = 0.198%

Therefore, the percent uncertainty for the given measurement is approximately 0.198%.
