A. 314 because when you use the formula for the GPE ; GPE=MGH or means mass times gravity time height (4x8x9.8) and thats equivalent to 313.6 which rounds up to 314. Hope it helps

Answer:

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

P.E = mgh

m = mass

g = acceleration due to gravity

h = height

Put the value into the formula

P.E=4\times9.8\times8

P.E=313.6=314\ J

Hence, The gravitational potential energy is 314 J.

Answer:

If we are looking for evidence of something that exists outside of our visible Universe and leaves no trace within it, it seems that the idea of a Multiverse is fundamentally untestable.  But there are all sorts of things that we cannot observe that we know must be true. Decades before we directly detected gravitational waves, we knew that they must exist, because we observed their effects.

Explanation:

Maybe helps lol
