Ernest Rutherford's gold-foil experiment showed the density of atoms.
<span>The experiment proved that most of an atom is empty space with a very small positively charged nucleus in the middle.
So, from the given statements he following is true:
</span><span>Ernest Rutherford's gold-foil experiment showed </span>the existence of a dense, positively charged center in an atom.
It would be the needle pressure gage temp check
Answer:
D orbitals begin filling with electrons after the orbital found in the 4s sublevel is filled. This occurs because the d sublevel

Answer:
Therefore electric conductivity 
=1.46 (Ω-m)⁻¹
Explanation:
Here σ= electrical conductivity
= current = 0.1 A
= length= 38 mm= 38×10⁻³ m
v= voltage = 12.5 V
A = area = 
= 
m²
=1.46 (Ω-m)⁻¹
Therefore electric conductivity =1.46 (Ω-m)⁻¹
