Do you support trucks are identical each box loaded on the truck has the same mask choose the truck that has the greatest force of gravity acting on it?

gravitational force of earth is given by

so here the force will depend on the product of mass and gravity

so here force will be more if we took the condition of more masses

so here in 3rd figure

there will be maximum force of gravity on it

because it will have 6 boxes so there will be maximum mass

So figure of truck with 6 boxes on it is correct answer

unbalanced force

explanation:

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.
