Question

In an experiment on the conservation of angular momentum, a student needs to find the angular momentum L of a uniform disk of mass M and radius R as it rotates with angular velocity . She makes the following measurements: ? = 1.10 ± 0.01 ?? ? = 0.250 ± 0.005 ? ? = 21.5 ± 0.4 ???/? and calculates L using ? = 1 2 ?? 2? (you will learn where this formula comes from later in PHYS 206.) What is her answer for L with its uncertainty? (You can consider the three original uncertainties independent.)

Please explain steps.

Answer 1

Uncertainty can be calculated by using relative error formula easly.
