Two particles with charges +6e and -10e are initially very far apart effectively an infinite distance apart They are then fixed at positions that are 6.25 x 10^12 m apart. What is EPEfinal - EPEinitial, which is the change in the electric potential energy?

Sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) attraction that bonds them together.

What accounts for an increase in the temperature of a gas that is kept at constant volume? a. energy has been removed as heat from the gas. b. energy has been added as heat to the gas. c. energy has been removed as work done by the gas. d. energy has been added as work done by the gas.

Why do atoms emit energy of only specific wavelengths
