Respuesta :
The student that is correct is C. Student B is correct because Newton’s 1st Law of Motion states that if the chair were to be exerting a force on the student, her motion would change.
According to Newton's third law of motion, there's an equal and opposite reaction force for every action force. It should be noted that when an individual sits on a chair, the chair is actually exerting a force back on her in reaction to the force exerted upon the chair.
Student A is incorrect because when she sits down on a chair, the force that she's exerting on the chair is not the only thing that happens because the chair exerts a force back. Therefore, as the chair were to be exerting a force on the student, her motion would change.
