A rock is thrown from a height of 10 m. It is initially thrown at an angle of 65° below the horizontal. If it takes 0.8 s to hit the ground, what was the rock’s initial speed? Air resistance can be neglected. A 20.3 m/s B 8.58 m/s C 7.33 m/s D 18.1 m/s E 9.47 m/s

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.
