Explain why the normal force and the force of gravity acting on a book as it sits on a desk are not Newton’s Third Law of Motion force pairs. in 35 length wording like a 9th gradre

The normal force and the force of gravity acting on a book on a desk are not Newton's Third Law force pairs because they do not act on different objects. Newton's Third Law states that for every action, there is an equal and opposite reaction between two different objects. However, in this case, the normal force and the force of gravity are acting on the same book, not on different objects.
