Generally speaking for a uni grad, the majority of jobs would be on site, is that a correct assumption? Say for chem eng.

Supposedly it loses energy by releasing EMR while orbiting. This is the point I don't understand.

I realse his model had problems. I am just trying to understand why his model was flawed. His model would collapse due to the electron spiraling into the nucleus, however I dont understand why the electron loses energy.

I don't complete understand. From what I gather. The lattice shifts so there is like a tunnel if you like, that accelerates the electrns due to the positive charge. I also assume the 0 resistance is due to the stronge electric field of these cations guiding the electrons through? So how...

According to numerous sources it would. Jacaranda. "Rutherford knew that if the electrons were in orbit around the nucleu,s they would be accelerating. They would be expected to be emitting emr in accordance with the theories of Maxwell and, ofcourse, the atom would be unstable" It's saying...

If a electron orbited a nuclei, why would it continuously release energy?

Well not instantly. If their projected HSC score is higher, they could still "beat you" However generally the people who drop out tend to have lower SC scores.

Anybody wanna explain this? edit: particularly why cooper pairs help super conductivity. What would happen if they didn't exist? Wouldnt the lone eletron still gain a passage.

x = atan(2) - atan(0.5) let arctan 2 = a arc tan 0.5 = b tan x = tan (a-b) tan x= ( a-b )/1+tanaxtanb tan x= 3/4 x = arctan 3/4 thus atan(2) - atan(0.5) = aarctan 3/4

So what % of people employed within engineering wear hardhats.

Complete truth. Ignore all other posts.

The information you've given is too vague to give an accurate estimate. If you could be bothered, please post your exact schools rank (or name). Exact marks and ranks. Rather than 70-90. Ty

Nobody actually answered the question. Why doesn't heating anions have flames/colours? Something to do with valence shell filled, thus no other electrons are able to reach an excited energy level? I have no idea, just speculating

Why do you want to know about bands? Bands are stupid, they mean nothing :S Also what do you want to know about bands in particular ?

yes.

A (4,5) B (1,-1) C (-2, -7) Looking at the X value of A. It goes down by 3 at B It goes down again by the sam amount to C This is the same for Y value (only goes down by 6)

The difference of the x,y values of point C is equal to the difference between A and B. e.g. If A was (1,1) and B was (3,3) then C would be (5,5) Assuming ABC were collinear and B is in the middle
