The rock is tied to a string and swung in a circular path by a boy as shown. The radius of the circular path is 0.6 meters and
the rock makes 100 rounds in 1 minute. The velocity of the rock
is_m/s

Which graph represents motion with an object with positive velocity that is located at a position of 3 meters at a time of 0 seconds? a) a b) bb eliminate c) c d) d

The two required components for a generator

(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
