Answer : The distance between the two atoms is 
Explanation :
The The formula used for moment of inertia for one atom is:
The formula used for moment of inertia for two atom is:
where,
I = moment inertia = 
r = distance of atom from axis of rotation
m = mass of atom = 
Now put all the given values in the above formula, we get:
Now we have to calculate the distance between the two atoms.
Formula used :
where,
d = distance between the two atoms
Therefore, the distance between the two atoms is
<h3>The features discussed are: Plateaus, deserts, deltas, mesas, basins, foothills, marshes, and swamps. Plateaus are elevated regions that are flat on top. Deserts are large areas that receive less than 10 inches of precipitation a year. Antarctica is the world's largest desert.Geography Landforms & Physical Features.

Explanation:
Avogadro number is 6.023 x 10(23).
A mole of CaCO3 (calcium carbonate) has one mole (Avogadro number) of Ca atoms, one mole of C atoms and 3 moles of O atoms.
Answer:
- <u>21.4 ml (second choice)</u>
Explanation:
<u>1) Data:</u>
a) C₁ = 60.0% (initial solution)
b) V₁ = 30.0 ml (initial solution)
c) C₂ = 0% (pure water)
d) V₂ = ? (pure water)
e) C₃ = 35.0% (final concentration)
<u>2) Formula:</u>
- C₁V₁ + C₂V₂ = C₃V₃
- V₁ + V₂ = V₃ (assuming volume addtivity)
<u>3) Solution:</u>
<u />
a) Substitute values in the first formula:
- 60.0% × 30 ml + 0 = 35% (30 ml + V₂)
b) Solve the equation (units are supressed just to manipulate the terms)
- V₂ = 7.5 / 0.35 = 21.4 ml ← answer
