GEO 702 Lecture Notes - Lecture 2: Ethnocentrism

Bob has an electric motor and a generator. Which pairs of energy terms are the most closely related to the development of a motor and a generator?

In the development of Young's double-slit experiment, a smallangle approximation (tan θ ≈ sin θ) was used to find the lateraldisplacements of the maxima (bright) and the minima (dark)positions. How good is this approximation? For example, what is thepercentage error for θ = 10 degrees?

When a honeybee flies through the air, it develops a charge of +19pc. How many electrons did it lose in the process of acquiring the charge?
