If he were to try to jump without giving that downward push, there would be no opposite push from the ground, and two things would happen: (1) shaun would not get very high off the ground, and (2) shaun’s board would not stay pressed against his feet, having no upward force applied to it. the passage above reflects the principles of a. newton’s first law of motion c. newton’s second law of motion b. newton’s third law of motion d. all of the above

Newton’s third law of motion.

The first and second are not it because Those are when an external force is brought upon on an object. The third law is correct because every action in nature there is an opposite affect making it equal. That law applies here. Sorry if I explained that bad, but I know the answer is right.

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
