Answer:
A.
B.
C.
Explanation:
The capacitance of a capacitor is its ability to store charges. For parallel-plate capacitors, this ability depends the material between the plates, the common plate area and the plate separation. The relationship is
is the capacitance, is the common plate area, is the plate separation and is the permittivity of the material between the plates.
For air or free space, is called the permittivity of free space. In general, where is the relative permittivity or dielectric constant of the material between the plates. It is a factor that determines the strength of the material compared to air. In fact, for air or vacuum, .
The energy stored in a capacitor is the average of the product of its charge and voltage.
Its charge, , is related to its capacitance by (this is the electrical definition of capacitance, a ratio of the charge to its voltage; the previous formula is the geometric definition). Substituting this in the formula for ,
A. Substituting for in ,
B. When the distance is ,
C. When the distance is restored but with a dielectric material of dielectric constant, , inserted, we have
The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.
If the separation between the openings in a laser is increased, then the distance between the interference fringes decreases
<h3>What is Interference fringe ?</h3>
Interference fringe refers to bands caused by different lights which can be found in phase or not each other.
- Distances between laser fringes are short which is due to light wavelength.
- The interference fringes can be estimated by knowing slit separation and wavelength.
In conclusion, if the separation between the openings in a laser is increased, then the distance between the interference fringe decreases
