The difference in air pressure which is created by the molecules in air help to move kite up into the air.
<u>Explanation:</u>
When air moves faster, pressure of air becomes less. Air moves at a faster speed above the kite than below it and so its pressure is less on top of kite. The air pressure below kite is less. This difference in pressure results in uplifting of kite. Molecules of air with high pressure exerts more force on kite from bottom and thus pushing it up in air.
The greater is the difference between air pressure above kite and air pressure below kite, greater is the amount of force exerted on kite and hence, it reaches a greater height.
The human foot has two arches, but the chimpanzee foot has only one.
It couldn't be analysed chemically because it's chemical composition is to complex. It would be hard for us to analyse them because once it has been removed from the organism, it ends as protoplasm only.
Contact forces have a stronger impact on motion, compared to noncontact forces
The answer would be D being those are all learned or earned attributes.
