Same answer as the first one above
18.5164213 if you divide them both you get that number so the volceity is the number shown above.
<span> Beryllium has an exclusive </span>+2<span> oxidation state in all of its compounds</span>
Answer: C. 12.6
Explanation: 2*pi*1.8= 11.304
11.304/0.9= 12.56
If you are asking for a proof on having at least 3 dimensions in space, you can find the physical proof anywhere in your daily life activities. Just the fact that solids have volumes is a proof already that we live in a three-dimensional space. We can move forwards, backwards, sidewards and in all other directions possible.
When you go right into detail, the fundamental laws governing these proofs are very technical. They have differential equations to show as proof. It is too detailed to discuss here. The important things is that, these fundamental laws are what explains the science in our basic activities and natural phenomena:
*Gravitation and planetary motion
* Translation, rotation, magnetic field, forces
* Integrals of equations:
