Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
Calculate the combined uncertainty of 5.0 ± 0.2 and 3.0 ± 0.1.
💡 Hint: Use δQ = sqrt[(σx)² + (σy)²].
Question 2
Easy
If A = 10.0 ± 0.5 and B = 25.0 ± 1.0, what is the total uncertainty when adding A and B?
💡 Hint: Add in quadrature.
