how does this photograph illustrate newtons third law of motion? a the greater the swimmers acceleration, the more force applied and the lower his mass. b the more force the swimmer applies back on the wall, the faster his movement forward in the water. c in order for the swimmer to move forward in the water there must be an unbalanced force acting on the swimmer. d the force acting forward is greater than the force acting in the opposite direction: the swimmer accelerates.
Answer
# Brief Explanations:
Newton's third - law states that for every action, there is an equal and opposite reaction. When the swimmer pushes back on the wall (action force), the wall exerts an equal and opposite force on the swimmer (reaction force), propelling the swimmer forward. Option B correctly describes this principle. Option A relates to Newton's second law ($F = ma$). Option C is about Newton's first law (unbalanced forces cause acceleration). Option D is also more related to the concept of unbalanced forces in Newton's first law rather than the action - reaction pair in the third law.
# Answer:
B. The more force the swimmer applies back on the wall, the faster his movement forward in the water.
