Practice problems
1. A cannon on a pirate ship was fired at an angle of 30 °, and the cannon ball came out of
the cannon at 40 m/s. Assuming we can neglect air resistance and that g=9.8m/s“,
calculate:
angle = 30
(Make table and write the given values)

Make table and write the given values

answer:

angle = 30

Explanation:

lol

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.

i think the answer is bone
