7 questions
Explain the difference between absolute uncertainty and percentage uncertainty. Give an example of when it might be more useful to use percentage uncertainty.
A rectangle's length is measured to be 5.0 ± 0.1 cm and its width is 3.0 ± 0.1 cm. Calculate the area of the rectangle and the uncertainty in the area.
