When the mass of the sun is larger, earth moves around the sun at a faster or slower pace. when the mass of the sun is smaller, earth moves around the sun at a faster or slower pace. when earth is closer to the sun, its orbit becomes faster or slower. when earth is farther to the sun, its orbit becomes faster or slower.

(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
