A mass of 2000 kg is raised 5.0 m in 10 seconds. What is the kinetic energy of the mass at this height?

0 J

Explanation:

The mass is not moving, therefore the kinetic energy is 0.

(I had this same question and the answer is 0)

they are playing too much beyblade in the office

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.
