1. An electron travels toward the right side of the page at a speed v. There is a magnetic field B directed into the page. In which direction will the magnetic force on the electron be directed?

2. An alpha particle travels toward the top of the page. There is a magnetic field B directed out of the page, determine the direction of the magnetic force on the alpha particle points.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

i think its d if wrong im sorry
