Electron, photon and proton carry momentum .
- De Broglie derived the relationship between the wavelength and momentum of matter. This relationship is known as de Broglie's relationship.
- De Broglie's relationship is given by
...(1) - Momentum is the product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction.
Equation (1) can be written as 
where λ is known as de Broglie wavelength and p is momentum , h = Plank’s constant
For photon , the momentum is given by 
...(2) where c is the speed is the speed of light .
From equation (1) and (2) we can conclude that electron, photon and proton carry momentum .

The frequency f of the AC source is determined as 0.446 Xc.
<h3>
Frequency of the AC source</h3>
The frequency of the AC source is calculated as follows;
Xc ≡ 1/2fC
where;
- Xc is the capacitive reactance
- f is frequency
- C is capacitance
fC = 2Xc
f = 2Xc / C
f = (2Xc)/4.48
f = 0.446 Xc
Thus, the frequency f of the AC source is determined as 0.446 Xc.

Answer: Binary star system
Explanation:
Binary star system is the system that is composed of two stars that are found in the orbits which rotate around same center of mass.These system are also denoted as multi-star systems.
These system tends to appear as light in form of particular point when seen from unequipped eye but clarity can be gained by using equipment and tools for actual view.
