Solar power: in this problem you will provide back-of-the envelop calculations for a small solar generator. the problem relies on your ability to calculate things like p iv, area, etc. 4. estimate how much power could be generated by the solar panel if it worked with maximum efficiency. (this is a general physics style calculation). estimate how much power is actually used in the rotation of the propeller blades photo-cells are often based on the cds semi-conductor device. explain how a cds solar cell works. how might the cds solar cell be responsible for the entire loss of energy in this system?

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.

truck y has a greater velocity than truck x.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
