Here is a graph of speed vs time. If the object is moving to the east, which BEST describes the speed and velocity of the graph? Group of answer choices Both speed and velocity are changing. The speed and velocity remain constant. The speed is constant and velocity is changing. The speed is constant and velocity is changing.

Both speed and velocity are changing.

Explanation:

They are both going up so both are changing

this is poiselle's equation from fluid mechanic in physics. mech eng

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.
