When the core runs out of hydrogen to fuse, then it starts fusing the helium. This happens because a star cannot create more hydrogen.
Answer:
The distance that you marginally able to discern that there are two headlights rather than a single light source is 6.084 km
Explanation:
Given:
d = distance = 0.679 m
λ = wavelength of the light = 537 nm = 537x10⁻⁹m
dp = pupil diameter = 4.81 mm = 0.00481 m
Question: What distance, in kilometers, are you marginally able to discern that there are two headlights rather than a single light source, dx = ?
For the separation of the peak from the central maximum it is:

In this case, the two small sources of the headlights have the same angle as the images that form inside the eye

To solve this problem we will apply the concepts related to the electric field, linear charge density and electrostatic force.
The electric field is

Here,
= Linear charge density
= Permittivity of free space
r = Distance
The linear charge density can be written as,
Linear charge density is given as

Replacing,


The initial and final electric Force can be written as function of the charge and the electric field as


If we replace the value for the electric field we have,

Length is one third at the end, then

The ratio of the force is


Therefore the required ratio is 3
In simple words, flux can be stated as the rate of flow of a fluid, radiant energy, or particles across a given area.
<u>Explanation:</u>
<u>Mutual Flux:</u>
- The magnetic lines present in among two magnets or solenoid is mutual flux.
- These are the lines in which the attraction and repulsion happens.
- The SI unit of mutual flux is the Henry
<u>Leakage Flux:</u>
- In simple words, it can be stated as the magnetic flux which does not follow the specially designed way in a magnetic circuit.
- Leakage flux in the induction motor takes spot due to current runs through the essence of the induction motor.
- The SI unit of Leakage flux is the Weber
<u>Magnetizing flux</u>
- Magnetic flux is an analysis of the entire magnetic field which moves in a given field
- In simple words can be defined as the Magnetic flux is what generates the field around a magnetic material.
- The SI unit of magnetic flux is the Weber
Energy is the capacity to do some type of work
