How did Niels Bohr create the Atomic theory

Niels Bohr created the Atomic theory by combining Rutherford's description of the nucleus and Planck's theory about quanta.

<h3>What is Bohr's atomic theory?</h3>

This was proposed by Neil Bohr and talks about how electrons move in fixed orbitals and not anywhere in between and was able to explain that each orbit has a fixed energy.

He explained the various activities and processes which were happening inside an atom thereby deducing a picture of atomic structure such as the presence of the subatomic particles in the nucleus and how they are involved in a chemical reaction.

The structure was that of a planetary model in which the negatively charged electrons orbit a small, positively charged nucleus which is similar to the planets.

This is therefore the different processes and ways in which Bohr created his atomic theory.

Niels  Bohr created the Atomic theory after studying the way glowing, hot hydrogen that gives off light.

<h3>How did Niels Bohr create the Atomic theory?</h3>

He developed the atomic model after studying the glowing of hot hydrogen that gives off light. When a light bulb is lit, it gives all the different wavelengths of the light. Niels Bohr proposed an atomic theory for the hydrogen atom, which is based on quantum theory. He says in this theory that Electrons move around an orbit of the nucleus , and If the electrons jump from a lower-energy orbit to a higher energy orbit, the energy is released in orbit in the form of radiation.

so we can conclude Niels Bohr created the Atomic theory after studying the way glowing, hot hydrogen that gives off light.

What is the The most appropriate SI unit for measuring the length of an automobile
Ugo [173]
If you're talking about S.I. Unit then it must be "meter" (nothing else). Meter is the only S.I. Unit of length and it also uses in measuring the length of an automobile 'cause it varies from few meters to several thousand meters.

In short, Your Correct answer would be "meter" (m)

Hope this helps!

Electron spin: Radio astronomers can detect clouds of hydrogen too cool to radiate optical wavelengths of light by means of the
Ivan

Answer:

the magnetic field experienced by the electron is 0.0511 T

Explanation:

Given the data in the question;

Wavelength λ = 21 cm = 0.21 m

we know that Bohr magneton μ_B is 9.27 × 10⁻²⁴ J/T

Plank's constant h is 6.626 × 10⁻³⁴ J.s

speed of light c = 3 × 10⁸ m/s

protein spin causes magnetic field in hydrogen atom.

so

Initial potential energy = -μ_BB × cos0°

= -μ_BB × 1

= -μ_BB

Final potential energy = -μ_BB × cos180°

= -μ_BB × -1

= μ_BB

so change in energy will be;

ΔE = μ_BB - ( -μ_BB )

ΔE = 2μ_BB

now, difference in energy levels will be;

ΔE = hc/λ

2μ_BB = hc/λ

2μ_BBλ = hc

B = hc /  2μ_Bλ

so we substitute

B = [(6.626 × 10⁻³⁴) × (3 × 10⁸)]  /  [2(9.27 × 10⁻²⁴) × 0.21 ]

B = [ 1.9878 × 10⁻²⁵ ]  /  [ 3.8934 × 10⁻²⁴ ]

B = 510556326.09

B = 0.0511 T

Therefore, the magnetic field experienced by the electron is 0.0511 T

Why is it important for a muscle to be attached to a fixed origin at one end and a moving insertion at the other? Discuss how th
vlabodo [156]
Muscles function only by contracting. This makes it necessary for one end of the muscle to be fixed and the other mobile.
Take the bicep for example.
Its origin is at the shoulder and its two heads connect to the bones of the forearm, the radius and ulna.
Now, had the muscle not been fixed at one end, and contracted, it would pull both our shoulder and forearm together resulting in an ineffective movement. The desired motion is to lift the forearm (proximal and distal movement) which can only be achieved if the bicep is fixed at the shoulder and allowed to move at the forearm.

I am trying to find the magnitude of a resultant vector. Do i take inconsideration the negatives when i find the x &amp; y compo
attashe74 [19]
Absolutely !  If you have two vectors with equal magnitudes and opposite
directions, then one of them is the negative of the other.  Their correct
vector sum is zero, and that's exactly the magnitude of the resultant vector.

(Think of fifty football players pulling on each end of the rope in a tug-of-war. 
Their forces are equal in magnitude but opposite in sign, and the flag that
hangs from the middle of the rope goes nowhere, because the resultant
force on it is zero.)

This gross, messy explanation is completely applicable when you're totaling up
the x-components or the y-components.
