Consider two point particles that have charge +e, are at rest, and are separated by 2.7 x 10-15 m.

1) how much work was required to bring them together from a very large separation distance? kev

2) if they are released, how much kinetic energy will each have when they are separated by twice their separation at release? kev

3) the mass of each particle is 1.00 u (1.00 amu). what speed will each have when they are very far from each other? m/s

Which force is most responsible for binding together an atom's protons and neutrons? electrostatic gravitational nuclear magnetic

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
