A student lifts an apple to a height of 1 m.
The apple weighs 1 N. How
much work does the student
do on the apple?

Use the work formula:

W = Fd

Replacing we have:

W = 1 N * 1 m

Resolving operation:

W = 1 J

The work efectuated is 1 Joule.

-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.
