Answer:
51 Ω.
Explanation:
We'll begin by calculating the equivalent resistance of R₁ and R₃. This can be obtained as follow:
Resistor 1 (R₁) = 40 Ω
Resistor 3 (R₃) = 70.8 Ω
Equivalent Resistance of R₁ and R₃ (R₁ₙ₃) =?
Since the two resistors are in parallel connection, their equivalent can be obtained as follow:
R₁ₙ₃ = R₁ × R₃ / R₁ + R₃
R₁ₙ₃ = 40 × 70.8 / 40 + 70.8
R₁ₙ₃ = 2832 / 110.8
R₁ₙ₃ = 25.6 Ω
Finally, we shall determine the equivalent resistance of the group. This can be obtained as follow:
Equivalent Resistance of R₁ and R₃ (R₁ₙ₃) = 25.6 Ω
Resistor 2 (R₂) = 25.4 Ω
Equivalent Resistance (Rₑq) =?
Rₑq = R₁ₙ₃ + R₂ (series connection)
Rₑq = 25.6 + 25.4
Rₑq = 51 Ω
Therefore, the equivalent resistance of the group is 51 Ω.
<u>Answer:</u>
For a. Neutrons and electrons also form an atom.
For b. The element is oxygen which is a non-metal and will form a negative ion while forming ionic bond.
<u>Explanation:</u>
There are 3 subatomic particles which form an atom. These are neutrons, protons and electrons.
Neutrons carry no charge, protons carry positive charge and electrons carry negative charge. Neutrons and protons are present in nucleus and electrons revolve around the nucleus.
The energy which is present between neutrons and protons are nuclear energy and the energy which is present between electrons and protons are electrostatic energy.
In an element, number of protons is always equal to the number of electrons. The atomic number is equal to the number of protons or electrons. The element which has atomic number 8 is Oxygen.
The electronic configuration of this element is 
This element requires only 2 electrons to form a stable electronic configuration. An element which gains electron is considered as a non-metal and forms a negative ion because number of electrons increases.
Answer:
The number is 
Explanation:
From the question we are told that
The wavelength is 
The length of the glass plates is 
The distance between the plates (radius of wire ) = 
Generally the condition for constructive interference in a film is mathematically represented as
![2 * t = [m + \frac{1}{2} ]\lambda](https://tex.z-dn.net/?f=2%20%2A%20%20t%20%20%3D%20%5Bm%20%2B%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5D%5Clambda)
Where t is the thickness of the separation between the glass i.e
t = 0 at the edge where the glasses are touching each other and
t = 2d at the edge where the glasses are separated by the wire
m is the order of the fringe it starts from 0, 1 , 2 ...
So
![2 * 2 * d = [m + \frac{1}{2} ] 520 *10^{-9}](https://tex.z-dn.net/?f=2%20%2A%20%202%20%2A%20d%20%20%20%3D%20%5Bm%20%2B%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5D%20520%20%2A10%5E%7B-9%7D)
=> ![2 * 2 * (2.8 *10^{-5}) = [m + \frac{1}{2} ] 520 *10^{-9}](https://tex.z-dn.net/?f=2%20%2A%20%202%20%2A%20%20%20%282.8%20%2A10%5E%7B-5%7D%29%20%3D%20%5Bm%20%2B%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5D%20520%20%2A10%5E%7B-9%7D)
=>

given that we start counting m from zero
it means that the number of bright fringes that would appear is
