Quanta to Quarks people~! (1 Viewer)

[little master]

oh i didnt mention the heseinberg uncertainty...damn
did we have to elaborate it or just mention it since its only a four mark question

 

[abhi_89]

heisenberg - uncertainty principle. no 2 electron's can have the 4 same quantum numbers.


i think you'll find that your COMPLETELY WRONG by this...u have stated pauli's exclusion principle.. heisenberg's is ragarding position and momentum of a particle.. sheesh

 

[abhi_89]

yeah for that question i got something like 1.06 x 10^-19 Joules? anyone get that

yep i got exactly that

 

[SureBluff]

31) I'll simplify all the answers

ai) because electron emit photon when going from higher to lower
aii) easy

bi) discussion in class, if experiement, repeat experiment and experiment with 1 variable at a time.
bii) H-uncertainty principal, P-exclusion principal,

c) chain reaction used in nuclear reactor, control rods absorb excess 2 neutron allowing 1 neutron to split another U and so on.

di) AC reverses polarity of Dees accelerating the particle in between the 2 dees, F = qvB = (mv^2)/r
dii) break particles apart to study quarks which otherwise doesn't exist naturally in world.
diii) Proton - uud, Neutron - ddu.

 

[abhi_89]

yeah.

i wrote exclusion princple [elaborated on it]
heseinberg uncertainty [elaborated]
and then prediction of neutrino [elaborated]

TOUCHE!!i thought i was only one going on about the neutrino

Quanta to Quarks was easy this year.... the 7 mark question was a bit hard to get out but once you started writing it seemed easy......
the only part i found really hard to answer was the cyclotron thing one... thats probably cos i didnt really study it or go over it....
other than that Q 2 Q was abit too easy this year.... anyone else find this the case?

 

[SureBluff]

Hopefully, I'd get 24-25/25 for QTQ this year. I mentioned everything in this topic and I found it really easy. The only way I can possibly lose a mark is if the markers are harsh. For the 7 mark nuclear reactor question I described the process of chain reaction but I think I may have forgot to call it a 'chain reaction'. Hopefully they only take 1 mark off of that or just overlook it. sigh, I suppose it they were mean, they could take 2-3 marks off.

bi) discussion in class, if experiement, repeat experiment and experiment with 1 variable at a time.

for tht question, ur gathering, processing and analysing info.
reliability doesn't equal repetition of an inclass experiment

i talked about cross-referencing the information that was gathered with other websites and ensuring tht the websites were reliable [eg: nasa, etc]

 

[Benmc]

How many pages did people write for the 7 marker?

I can't remember if i wrote Pauli said no two atoms (or was it electrons) can have 4 same qauntum numebers.

But everything else i mentioned.
Ie. Neutrino - Pauli
Heinsenberg uncertainty principle.

 

[suchet_i]

this is what i talked about
a) 1) didnt put the whole table on because calculator showed math error
b) 1) ask teacher if she thought my homework was good
2) helped explain quark and leptons -- i developed on that
c) i wrote in detail about the discovery of the neutron and neutrino and then the uranium spectral lines
d) 1) uses the gravity to inversity speed up stuff
2) it helped us understand the composition of superconductors
3) i think its a trick question .. protons and neutrons dont contain quarks

i m aiming for atleast 24/25.. CMONN!!

lol.
ur gonna get a b6 for sure!

 

[suchet_i]

i sure hope so man ..

 

[tauren]

for the 7 mark question, i talked about how neutron scattering and that it is a natural transmutation, which i hope it is correct

 

[suchet_i]

neutron scattering .. uhh .. noob .. its ba and kr scattering coz thats whats released .. but u shdnt forget the imperical formula used to devise the uncertainty of u-235

 

[BobbyRocks]

Wdf?!?! R u serious .... NEutron scttertign isnt transmuation you loser, i talked about how the questions shows a chemicasl reaction in which neutrons Are forumsa and u use netruon to get energy but using them in a generator by ... and Thjen I said stuff about Einsteins theory of plank and lepotons

 

[tauren]

no neutron scattering????, but my teacher told me that write neutron scattering to sound smart and i'll definately get full marks

 

[BobbyRocks]

oh Ok, i think they will accept Like anthing at All Coz it was Soo hard, probly get 6 opr 7

 

[suchet_i]

i heard u can get more than 7 for that question (out of 7) if the markers like ur number :S

 

[shinji]

hmm. what's with all the trolls. -_-"

 

[tauren]

wat if u put money inside the exam paper for the markers?? will that get u extra marks?
