If a man weighs 900n on earth ,what is his weight on jupiter where the acceleration due to gravity is 25.9 m/s^2?

He weight 2331N on jupiter

Explanation:

900N = 90kg

F = m × a

F = 90 × 25.9

= 2331N

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.
