Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What formula do you use to propagate uncertainty in multiplication?
- δQ = δx + δy
- δQ/Q = sqrt[(δx/x)² + (δy/y)²]
- δQ = sqrt[(δx)² + (δy)²]
💡 Hint: Think about how ratios work when combining uncertainties.
Question 2
True or False: In propagation of uncertainty, we can simply add absolute uncertainties.
- True
- False
💡 Hint: Reflect on the rules for combining uncertainties when doing complex operations.

Challenge Problems
Push your limits with challenges.
Question 1
Calculate total uncertainty when combining measurements where x = 2.0 ± 0.1 and y = 3.0 ± 0.2, where Q = x/y.
💡 Hint: Start by calculating the relative uncertainties, then look at how to combine them for Q.
Question 2
A cylindrical container has a radius of r = 1.5 ± 0.05 m and a height h = 4 ± 0.1 m. Calculate the uncertainty in the volume V = πr²h.
💡 Hint: Apply the formula systematically: calculate the volume first, then unravel the uncertainties step by step.
