Amy walks 3 m from her desk to the teacher's desk. from the teacher's desk, she then walks 4 m in the opposite direction to the classroom door. which table correctly represents both the distance and displacement of amy's motion?

distance = 7 m

displacement = 5 m

Explanation:

distance moved by Amy is the total path length that she moved

so it is given as

here we have

so we have

now since both the distance that she moved is perpendicular to each other so total displacement of Amy is given as

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .

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.
