Select an example of a vertical motion with a positive velocity and a negative acceleration. select the correct example and explanation. a)a tossed ball on its way down. as the ball moves down it is slowing down, hence the acceleration is opposite the bvelocity (negative).b) a tossed ball on its way upward. as the ball moves upward it is slowing down, hence the acceleration is pointing in the same direction as the velocity (negative).c) a tossed ball on its way upward. as the ball moves upward it is slowing down, hence the acceleration is opposite the velocity (negative).d) a tossed ball on its way down. as the ball moves down it is slowing down, hence the acceleration is pointing in the same direction as the velocity (negative).

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
