Is anyone good at editing pictures?

(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

How can you increase the strength of an electromagnet?

The force it would take to accelerate an 900-kg car at the rate of 6m/s2
