A bear and you are pulling in opposite directions on a picnic basket with a mass of 10 kg. The basket moves with constant velocity towards the bear, who pulls with 180 N. If the coefficient of friction is 0.5, how hard are you pulling? Draw the free body diagram and net force equations, and calculate all forces.

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.

a sonic boom is a loud boom that breaks the sound barrier

explanation:

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
