Adog of mass 4 kg runs up a hill of height 8 m. how much gravitational potential energy does the dog gain? a.314 j b.229 j c.32 j d.78 j

The gravitational potential energy is 314 J.

(A) is correct option.

Explanation:  

Given that,

Mass of dog = 4 kg

Height = 8 m

We need to calculate the potential energy

Using formula of potential energy

m = mass

g = acceleration due to gravity

h = height

Put the value into the formula

Hence, The gravitational potential energy is 314 J.

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.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
