Agirl attaches the end of her jump rope to the trunk of a tree. what evidence exists that the rope is a transverse wave?

When the girl generates a wave on the rope, we clearly see that it advances forward, towards the tree. So, the direction of wave movement is either to the left or to the right depending on where the tree is located.

Under this scenario, when we see how the rope moves, we see that it moves in up/down direction as the wave pulse passes. Since the up/down direction is perpendicular to the right/left direction, we conclude that the particles that make up the rope move perpendicularly to the direction of wave movement. Hence, we know that it is an example of a Transverse Wave.

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.
