D. They are closest to the nucleus. Therefore elections with the highest are found further away.
Density is a property of the material, so both spheres would have the same density because they are made of the same material.
Answer:
e. 27 rho.
Explanation:
The density of an object, assumed constant, is defined as the relationship between the mass and the volume.
If the object is compressed in such a way that the diameter is reduced to 1/3, this means, that the radius will be reduced in the same proportion.
Now, if the mass remains the same (the compression can't change it) , the volume (assumed to be a perfect sphere) will be reduced also:
V₀ = 4/3*π*r³
Vf= 4/3*π*(r/3)³ = 4/3*π*(r³/27) = V₀/27
As the volume is in in the denominator of the expression for density, this means that the new density will be equal to 27 times the original one:
ρ₀ = m/ V₀
ρ₁ = m/ V₁ = m/ (V₀/27) = 27* (m/V₀) = 27*ρ₀
You're probably refering to a theory. A theory is a conceptual framework about a certain topic out of which we can infer many different hypothesis on the same topic that should prove to be correct. If they're not, then the theory is not a theory in reality, because the inferences made out of the theory are not correct.
