1. A box with a mass of 6 kilograms is pushed with a net force of 10N to the right on a frictionless surface. Calculate the acceleration of the box. *

Explanation:

Given that,

Mass of the box, m = 6 kg

The net force acting on the box, F = 10 N

We need to find the acceleration of the box. We know that the force acting on an object is given by :

F = ma

a is the acceleration of the box,

So, the acceleration of the box is .

lol

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.
