You lift a 44 N box from the floor and place it on a shelf that is 1.5 m above the ground . How much work did you use in lifting the box ?

W = 66 J

Explanation:

Given that,

The weight of the box, W = 44 N

It is placed on a shelf that is 1.5 m above the ground.

We need to find the work done in lifting the box.

We know that,

Work done, W = Fd

So,

W = 44 N × 1.5 m

= 66 J

So, the required work done is equal to 66 J.

chemical properties of thing

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.
