Answer:
(a) 
(b) 
(c) 
Explanation:
(a) The orbital period is the time that the electron spend to travel the orbit of the atom. Thus, it is given by the length of the circular orbit divided by its velocity:

(b) Current means charge over time, So, in this case is charge over period:

(c) Magnetic moment is given by:

Here A is the area of the orbit.

Nuclear fusion is the process by which multiple nuclei join together to form a heavier nucleus.
Nuclear fusion of light elements releases the energy that causes stars to shine and hydrogen bombs to explode.
Nuclear fusion of heavy elements (absorbing energy) occurs in the extremely high-energy conditions of supernova explosions.
Nuclear fusion in stars and supernovae is the primary process by which new natural elements are created.
It is this reaction that is harnessed in fusion power.
It takes considerable energy to force nuclei to fuse, even those of the lightest element, hydrogen.
Boyle’s law is P1V1 = P2V2. This shows that pressure and volume have an inverse relationship, so increase in pressure causes a decrease in volume. B is your answer

Answer:
The value is 
Explanation:
From the question we are told that
The potential of the proton is 
Generally the momentum of the particle is mathematically represented as

Here e is the charge on the proton with value

m is the mass of the proton with value 
So

=> 
So the de-Broglie wavelength isis mathematically represented as

Here h is the Planck's constant with value

=> 
=>
