Diagram A Diagram B
Earth at the Center
Sun at the Center
The two diagrams above are different models for the behavior of objects in our solar system. BOTH
diagrams show the Select
of celestial bodies in our solar system. The model
first proposed stated that the Earth was the center of the solar system. What was this model called?
(Diagram A) Select
Advances in technology provided evidence that caused them to rethink that model. It was
discovered to be incorrect. Scientists accepted the model in diagram B which states the Sun is the
center of the solar system. This model is called the Select

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.

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
