1.55 J of work was done on the object that moved 5 meters. How much force was applied to the object?

Work=force x displacement

Force =work/ displacement

F=1.55/5

F=0.31N

Explanation:

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

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.
