A boulder with a mass of 25 kilograms slides 30 meters to the right while experiencing a rightward applied force of 150 newtons and a leftward force of friction that is two thirds the magnitude of the applied force.
1. Calculate the magnitude of work done by the force of friction.
A. O joules
B. 1500 joules
C. 3000 joules
D. 4500 joules

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.

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.
