Answer:

Explanation:
Mass of the Sun = 
Amount of Hydrogen = 75% of Mass of Sun,
thus mass of Hydrogen (m) in the Sun is,

m = 
Speed of Light (c) = 
Thus, energy(E) produced if whole of hydrogen is converted into energy,
E = mc²



By definition we have that the energy at the top of the ramp is equal to the energy at the bottom of the ramp. This is due to the principle of energy conservation.
We have then:

The energy at the top is only potential energy:

Where,
- <em>m: mass
</em>
- <em>g: acceleration of gravity
</em>
- <em>h: vertical height of the ramp
</em>
The energy when it falls is transformed into kinetic energy and therefore:

Where,
- <em>v: object speed.
</em>
Therefore we have:

Answer:
The potential energy is transformed into kinetic energy.

The statement that is true concerning an atom would be C. The atomic number of an atom is equal to the number of protons.
Answer:
You are right. It is reflected
Explanation:
if it is concave then the light is reflected at one direction.
if it is convex the light is reflected outwards and they will travel away from the focal point and the light scatters or will be reflected to different directions

The moon orbiting the Earth
