Aball is traveling 24° above the horizontal at a speed of 12 m/s. what is the vertical component of its speed? 5.3 m/s 0 4.9 m/s 23.5 m/s 11.0 m/s

4.9 m/s

Explanation:

Let v = speed of the ball = 12 m/s

θ = Angle at which the ball is traveling = 24°

As the ball is traveling at an angle there will be two components. One horizontal component and one vertical component.

Vertical component of speed

∴ Vertical component of its speed is 4.9 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.
