Alinear track begins at 0 meters and has a total distance of 100 meters to the finish line. juliet starts at the 10-meter mark while practicing for a race. after running 45 meters, how far is she from the beginning of the track?

Explanation:

Juliet starts at the 10-meter mark.

Initial displacement from starting = 10 meter.

She runs 45 meters to the 100 meter line.

Displacement = 45 meters.

Final displacement from starting = Initial displacement from starting + 45

Final displacement from starting = 10 + 45

Final displacement from starting = 55

She will be 55 meter far from the beginning of the track.

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.
