bafter hit the ball for a home run. How long after you see the ball hit do
you hear the crack of the bat?
2. At Zion National Park a loud shout produces an echo 1.75 s later
from a colorful sandstone cliff. How far away from the shouter is the

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

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.
