Answer:
I think it is a or c hope this helps
I think it's C, longer wave length.
As the boulder falls off the cliff, the gravitational potential energy that the boulder has is converted into kinetic energy. If you do the calculations, you will see that the kinetic energy the boulder has is equal to the gravitational potential energy it had before it fell off a cliff.
Answer:
2. much hotter and much denser than its surface
Explanation:
We know that the temperature around the center of the Sun is about 1.57×10⁷ K and its density is about 162 g/cm³.
Now, the temperature and the density decrease as one moves outward from the center of the Sun, the temperature at the surface of the sun is about 5×10³ K and the density as an average in the surface is about 1.4 g/cm³.
Therefore the answer is:
2. much hotter and much denser than its surface.
I hope it helps you!
Have a nice day!
