A projectile is launched from the ground with an initial horizontal velocity of 6.0m/s [right] and an initial vertical velocity of 5.0/s [up]. At what angle from vertical is it launched?

θ = 39.8°

Explanation:

Her, we will use the trigonometric ratio of the tangent to find the launch angle of the projectile from the vertical:

where,

θ = launch angle from the vertical = ?

vy = vertical component of velocity = 5 m/s

vx = horizontal component of velocity = 6 m/s

Therefore,

θ = 39.8°

explanation:

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.
