Two electrons in a vacuum exert force of f = 3.8e-09 n on each other. they are then moved such that they are separated by x = 8.2 times their original distance. what is the force that the electrons experience at the new distance, f_n, in newtons? numeric: a numeric value is expected and not an expression. f_n = how far apart were the electrons originally in meters? numeric: a numeric value is expected and not an expression. d =

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
