You run from your house to a friend's house that is 4 km away. You then walk home. What distance did you travel? What was the displacement for the entire trip? Draw a picture to help you find the answer. * 9 points Distance 8 km, Displacement 8 km Distance 0 km, Displacement 8 km Distance 0 km, Displacement 0 km Distance 8 km, Displacement 0 km

C

Displacement 0 km Distance 8 km,

Explanation:

Given that You run from your house to a friend's house that is 4 km away. You then walk home. Either you run or walk both displacement and distance covered are concerned about the length covered.

The distance will be only the magnitude of the length covered.

The distance = 4 + 4 = 8km

While the displacement will comprise the magnitude of the length covered by considering the direction

Displacement = 4 - 4 = 0

Therefore, the correct answer is

Displacement 0 km Distance 8 km,

Which is option C

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.
