Elizabeth is pushing against a wall as she stretches before exercising as shown below. The wall pushes back against Elizabeth's hands with the same force in the opposite direction. Which of Newton's laws does this best demonstrate? A. Newton's universal law of gravitation B. Newton's third law of motion C. Newton's second law of motion D. Newton's first law of motion

Newton's third law of motion

Explanation:

According to Newton's third law of motion, for every action force there is an equal and opposite reaction force. In this case, the action force is Elizabeth pushing against the wall with her hands. As this happens, there is an equal and opposite reaction force in which the wall pushes back on Elizabeth's hands.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
