Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A variable x is measured as 5 ± 0.05 m. Calculate the resulting uncertainty when x is cubed.

💡 Hint: Remember to apply both the power and multiplication rules in uncertainty.

Challenge 2 Hard

An experiment notes a mass change in a reaction where uncertainty is 1% and the mass is measured at 200 g. If this mass is part of an exponential decay model, what’s the new uncertainty effecting the result?

💡 Hint: Keep in mind the consistent nature of relative uncertainties in exponential models.
