Which one(s) of the following statements is (are) correct for elastic collision between two objects? (a) total momentum is not conserved, but total kinetic energy is conserved.(b) neither the total momentum nor the total kinetic energy is conserved.(c) bother the total momentum and the total kinetic energy are conserved.(d) the amount of kinetic energy lost by one object is the same as the amount of kinetic energy gained by the other object.(e) the magnitude of the momentum lost by one object is the same as the magnitude of the momentum gained by the other object.(f) total momentum is conserved, but total kinetic energy is not conserved.

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.

what are the options.

explanation:

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
