A10 n board of uniform density is 5 meters long. it is supported on the left by a string bearing a 3 n upward force. in order to prevent the string from breaking, a person must place an upward force of 7 n at a position along the bottom surface of the board. at what distance from its left edge would they need to place this force in order for the board to be in static equilibrium?

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.

this could be newton#'s law of cooling. the cooling curve is exponential
