Atoy rocket engine is securely fastened to a large puck that can glide with negligible friction over a horizontal surface, taken as the xy plane. the 4.80-kg puck has a velocity of 1.00î m/s at one instant. eight seconds later, its velocity is (6.00î + 6.0ĵ) m/s.(a) assuming the rocket engine exerts a constant horizontal force, find the components of the force.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

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.
