Atomic structure applies to just that, atoms in isolation. Witness looking at atomic spectra using laboratory discharge tubes to ionise low pressure gases of atoms of the elements you want to examine for energy level structure (sodium and the yellow D line "doublet").Crystal structure applies to vast collections of atoms/molecules/ions in complicated geometrical arrays which form lattices. Simple cubic, body centred cubic, face centred cubic being a few "simple" examples.

Answer:
The radius described the proton moving is
r=3.91mm
Explanation:
The magnetic field that moving the proton with the velocity
v=15 km/s
To find the radius combinate the magnetic field with the mass of the proton and the charge of the proton
r = mv=eB
r = mv/eB
r = 3.9mm
Due to Ohm's law, I is proportional to V and 1/R:
I ∝ V
I ∝ 1/R
R is proportional to the wire length L:
R ∝ L
Therefore I is also proportional to 1/L:
I ∝ 1/L
Calculate the scale factor due to increased voltage:
k₁ = 24/12 = 2
Calculate the scale factor due to decreased wire length:
k₂ = 1/(0.5/1) = 2
Multiply the original current by the scale factors to get the new current:
I = I₀k₁k₂
I₀ = 100mA, k₁ = 2, k₂ = 2
I = 100(2)(2)
I = 400mA
Answer:
Time period of the osculation will be 2.1371 sec
Explanation:
We have given mass m = (B+25)
And the spring is stretched by (8.5 A )
Here A = 13 and B = 427
So mass m = 427+25 = 452 gram = 0.452 kg
Spring stretched x= 8.5×13 = 110.5 cm
As there is additional streching of spring by 3 cm
So new x = 110.5+3 = 113.5 = 1.135 m
Now we know that force is given by F = mg
And we also know that F = Kx
So 
Now we know that 
So
