A) What is the kinetic energy of an auto-mobile with a mass of 1297 kg traveling at a speed of 11 m/s? Answer in units of J.

b)What speed would a fly with a mass of 0.570 g need in order to have the same kinetic energy as the automobile?
Answer in units of m/s

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.

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic
