Physicists sometimes hypothesize the existence of the "gravitron". This would be a particle responsiible for the force of gravity. Would you expect the gravitron to be a part of the standard model for physics? a .Yes, because the standard model describes all the fundamental forces like gravity.

b. No, because the standard model does not include particles in the discussion.

c. Yes, because the standard model describes the effect of gravity on particles.

d. No, because the standard model describes only the fundamental forces other than gravity.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

explanation:

newton's third law, for every action there is an equal and opposite reaction.

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.
