Yeah, i agree with the wording of some of the questions. It's not an English test! Either you know your stuff or you don't. Bugger trying to trick people with complicated and nonsensical wording.

Phonons are vibrational states. BCS theory relies on phonons to describe how the cooper pairs occur. Definately not A Definately IS B And sorry, yes 2 is (a), lol

Probably cuz it is 760.26 :)

The nearest galaxy to ours is the Large Megallanic Cloud, with it's centre located 1.7x10^5 light years from Earth. Assume you are in a spacecraft travelling at a speed of 0.99999c towards the Large Megallanic cloud. a) In your frame of reference, what is the distance between Earth and the...

In that particular question you guys are talking about, it is definately t0, as it is YOUR frame of reference and relative to YOU it is not moving at velocity (hence t0) Essentially the answer should have come out to be tv = 170,001.70 years (t = d/s) t0 = tv (1-(v^2/c^2))^1/2 t0 =...

Conventional current is flowing into the page through side Y and out of the page through side X. Magnetic field is running from left to right across the page Using RHP rule, fingers pointing across the page, thumb pointing out of the page (for side X), experiences a force upwards. Therefore...

Well, here is what i think: 1. C 2. A 3. C 4. D 5. C 6. A 7. C 8. C 9. A 10. B (So many of my guys put in (c) here!!!) 11. B 12. D 13. B 14. C 15. A Opinions?

Just read through it, seems like a pretty decent paper. Not all that hard, but a couple of "tricky" questions. Q2Q is pretty damn easy, just about all my students breezed through that, but some of my students (especially those which do standard maths) had a bit of trouble in the other sections...

I predict something about Maxwell and Einstein and their contributions to quantum theory to be the big question in Q2Q

It depends on your school and how they enforce it. You may recieve an N-Award for non-completion of classword as you have not fulfilled all of the outcomes of the course. Even if it is just for the one thing. Basically, if you get an N-Award warning for one thing and do not redeem it by the...

Sorry mate, the class has filled up! :)

Found the following equation in a reliable book: I_{photo}=-ne\phi A where \phi =I_{0}/hf n = quantum efficiency e = charge on electron Io = intensity A = surface area of detector phi = incident photon flux density (# photons per sqcm per s) So what this says for equal intensity light...

This. Attempted example has now succeeded in confusing me further..

Not electrons passing a point, rather electrons passing a point per unit time. Imagine u r at the finish line of a quarter mile drag strip. Assume the drag car accelerates to max speed instantaneously. Left hand lane had car a, which does quarter mile in 15 secs, right is car b which travels...

Yes. It is pretty intense. If you are crap at Maths, dont even bother. I was one of the very few people who went well in the subject and sometimes it took me 30 mins to solve one problem on the homework sheets. I cant remember who the lecturer was when i did it, but i think it may have been...

Specialised subjects really dont kick in til the second year anyway. First year in science (flexible) and nano are basically the same i think? Even if you start to do nano and you do the nanosciences 1 and nanosciences 2 then transfer to regular science, you could always use those 2 subjects as...

I also did Tax Law during summer with Jim or James someone? Older fella, very sarcastic, lol.. I dont think the assessments were exactly the same though, as I have a friend who is doing it this semester and she had a midsemester, I didnt iirc. I just had a couple of in class tests. I am looking...

11/11 and 12/11 for me

I hope for ur sake you dont have Stephen Topple.. I have him for 22730 this semester Very poor indeed Although i did get a D for the midsem, and he said there were no HD's at all

Question i pose to you. Seeing as Current is defined as the amount of "charge" past a point per second. If you increase the frequency of the incident EMR, thus increasing KE of electron, thus increasing speed of the electron, there will be more electrons passing a defined point per second as...
