Two identical springs, each with a spring force constant latex: kk, are attached end to end. if a weight is hung from a single spring, it stretches the spring by a distance latex: dd. when this same mass is hung from the end of the two springs, which, again, are connected end-to-end, the total stretch of these springs is g

(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
