Aball is throw horizontally from the top of a building 29.3 m high. the ball strikes the ground at a point 99.4 m from the base of the building. what is the time he ball was in motion

We can solve this via the kinematic equation:

Where the vertical velocity is zero and so:

Since the height of the building is 29.3 meters then:

The ball was in motion for approximately 2.45 seconds

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.
