TBR Physics II Exam Questions & Answers 2024 *Electrostatics & magnetism* - ANSWER- Coulomb's law - ANSWER- Electric & gravitational forces - ANSWER- When voltage is applied across a wire, a current flows Imagine *e-'s go up V stairs* - ANSWER-*Electrons* move from *lower to higher voltage* (opposite to current "+ charge") The current makes electrons flow into the wire and out of the wire (equalling each other), so the net charge on a wire will not change. The *net charge i...

What are the 5 types of intermolecular forces? 1. Dispersion 2. Hydrogen bonding 3. Dipole-dipole 4. Ion-dipole 5. Ion-Ion Dispersion forces the weakest intermolecular force; a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles Hydrogen bonding forces stronger than dispersion forces its an attraction of hydrogen to O, F, and N Dipole-dipole forces intermolecular forces that exist between polar m...
