You will find two answers don't match. A little difference of sqrt of a
Dec 14, 2018 05:52
@Axoren combining 1 and 6 you will find what is wrong with the answer

Dec 14, 2018 05:47
Pls do write one for me. and then give a picture
Dec 14, 2018 05:46
no that was not the problem.
Dec 14, 2018 05:40
Pls write the actual answer. I really need this @Axoren
Dec 14, 2018 05:37
Are the terms inside ln correct? @Axoren

Dec 14, 2018 05:32
Actually googled it but there were two pages where they had a slight dissimilarity in the answers.

Hey what's the integral of sqrt (ax^2 +bx+c) write the ln format answer

May 20, 2018 16:33
OK thanks a lot
May 20, 2018 16:31
The black lines refer that those energies have been absorbed? Or emitted?
May 20, 2018 16:29
When energy is being transmitted will I see rainbow or a specific color (where only one orbit change is found)
May 20, 2018 16:25
Yeh
May 20, 2018 16:24
I see thanks a lot. Another little help. What quantization has to do with spectrum having black lines
May 20, 2018 16:23
I know they assumed n=1, but is that even correct to assume. Does that support in practical cases
May 20, 2018 16:21
They didn't bring the concept of Quantization. Rather they just simply used E=hv
May 20, 2018 16:20
If that's the case why in our textbook just divided the energy 100kj by plank's constant to get the value of the frequency. Is that theoretically correct?
May 20, 2018 16:19
But to get the energy of that photon I need to know it's frequency?
May 20, 2018 16:18
Ok I think I got it, I should always keep in mind that the 100kj energy will be absorbed be n numbers of photon?? @pentavalentcarbon
May 20, 2018 16:17
E=100KJ
May 20, 2018 16:16
E=nhv
May 20, 2018 16:14
@pentavalentcarbon
May 20, 2018 16:13
OK do you mean to say even though we know the energy difference between two levels is 100kj we don't know the energy of the photon in this case
May 20, 2018 16:10
Different Energy levels have different energies. So there are energy differences required to go from one energy level to another. Right?
May 20, 2018 16:08
The energy absorbtion or emission will always be an integer multiple of a quantized energy according to Plancks quantum theory
May 20, 2018 16:07
What is quantized energy actually?
May 20, 2018 16:01
@pentavalentcarbon just tell me Pls whether quantization is related to Bohr's model or not. If so how Pls elaborate
May 20, 2018 16:00
So to jump to the 4th shell from 3rd the required energy is 100kj , if this 100kj is absorbed by quantization. By n multiple a photon E=hv whose n multiple =nhv=100kj, how do we get the energy of photon here @pentavalentcarbon
May 20, 2018 15:58
Energy of n=4 is 300 kj
May 20, 2018 15:58
OK listen. Let's say the energy of n=3 is 200kj,
May 20, 2018 15:05
@pentavalentcarbon fine. As 100kj will be absorbed in a quantized way. Then it has to be n multiple of 1 quanta or photon. What would be the energy of this photon. Of whose n times =100kj
May 20, 2018 14:23
According to quantization it's said that emitted or absorbed energy is quantized. So when it's said in bohr's model an electron changes its orbit. Let's say the energy difference is 100kj, now, according to quantization is the 100kj itself a quantum. Or the 100kj will be absorbed in quantized way?
May 20, 2018 14:21
Hey everyone
May 5, 2018 16:26
Why doesn't electron emit energy in Bohr's Orbit (stationary orbit) ? As Rutherford's model can't describe why electrons don't fall into nucleus but in bohr's model bohr suggested that electrons stay in some specified stationary orbit where they don't lose energy. But why don't they lose energy there

Thank you so much, now it's clear :) @Semiclassical

I got that r represents here the radial distance fine, and when finding out two equal radial distance and showing that the change in distance is zero hence the radial velocity (speed) is zero, but what sign flip has to do anything with that
Apr 23, 2018 15:36
So how does it change sign? Since it's not a vector
Apr 23, 2018 15:34
Radial means vertical component?
Apr 23, 2018 15:33
@Semiclassical "" radial velocity goes to zero and changes sign""?
Apr 23, 2018 15:32
Apr 23, 2018 15:32
Oh I see. I am sending another picture, what does that mean by the line I circled
Apr 23, 2018 15:25
@Semiclassical what zero velocity has to do with the maximum radial distance since the radial velocity never becomes zero only the vertical component of velocity is zero at maximum point still there is no zero velocity. Can you please elaborate more

Hey guys while reading an article about the unusual characteristic of Projectile motion I came to know that for angle greater than 70.5288 ° the projectile starts oscillating. And we can find two points where the radial vectors magnitude is same. When I was reading the proof of this phenomenon I saw they used radial velocity =dr/dt= 0 then kept proceeding. But how could the radial velocity be zero? See the pictures
