apakah teori mengenai listrik statis itu benar atau salah? Dimana teori tersebut berkata bahwa elektron pada suatu benda yang netral dapat berpindah dari satu benda ke benda yang lain ketika terjadi kontak (dengan cara konduksi, digosokkan dan induksi), sehingga benda yang mendapatkan elektron akan bermuatan negatif. Benda yang bermuatan negatif dapat menarik benda lain yang bermuatan netral.

30 points - when can a theory be modified if a new type of technology allows for new observations that raise new questions? a. immediately, while the questions about the theory are being asked b. after new hypotheses related to the theory are tested in experiments c. only after the new observations disprove all parts of the theory d. while scientists begin to think about how the theory could improve

(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
