How many people does it take to put in a lightbulb

(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

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost

Decreased sensitivity to an unchanging stimulus is known as
