A person pushes a block 4 m with a force of 25 N. How much work is being done?

Explanation:

The work done by an object can be found by using the formula

workdone = force × distance

From the question we have

workdone = 25 × 4

We have the final answer as

Hope this helps you

pe = weightxheight = 2000x1000=2,000,000joules

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.
