The pilot of an airplane is flying 340 km/h due West relative to the air. If it encounters a wind blowing at 85 km/h, 35° North of East relative to the ground, what is the plane’s velocity relative to the ground?

the answer is a. at the equator

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.

it is a negative acceleration
