The launching velocity of a missile is 20.0 m/s, and it is shot at 53° above the horizontal. what is the horizontal component of the velocity at launch?

Given that

velocity (v) = 20 m/s ,

angle of missile (Θ) = 53°

Determine,   Horizontal component = v cos Θ

                                                           = 20 × cos 53

                                                            = 12 m/s

overcharge is the right answer system

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.
