Neon has 10 protons and 10 electrons. how many additional electrons would it take to fill the outer (second) electron shell?

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

Calculate the amount of heat produced when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v
