g Find the work WAB in electron volts done by the electric force on an electron that moves from point A to point B. Similarly, find WAC, WAD, and WAE. (Assume the electron starts and stops at rest. Enter your answers in eV.)

Astudent is given an assignment to demonstrate diffraction. he takes a photograph of a straw in a glass of water. the straw appears bent at the water level. which best describes this example? a) this is a good example of diffraction. b) this is an example of dispersion and not diffraction. c) this is an example of refraction and not diffraction. d) this is an example of reflection and not diffraction.

You are given a vector a = 125i and an unknown vector b that is perpendicular to a. the cross-product of these two vectors is a × b = 98k. what is the y-component of vector b?
