"Nate throws a ball straight downward, letting it bounce once before catching it. (we can ignore air resistance)
A. what is true about the acceleration AND the velocity of the ball on its way down?
(assume upward is a positive direction)
1. Acceleration increases and velocity is negative and thus decreasing
2. Acceleration remains constant and velocity is negative and thus decreasing
3.Acceleration is decreases and velocity is positive and increasing
4. Acceleration remains constant and velocity is negative and decreasing
(What of the four suggestions is correct?)

(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
