Quanta to Quarks thoughts (1 Viewer)

I hated it, part a) we didnt even do that in school, part b) i dont think any amount of study on alpha and beta decay could help you there, but i think i got 2-3/3 for iii. c) i wrote 2 pages for, 80% of which was english/general knowledge, 20% economics. and 0% phyiscs. d) was more like what i was expecting, im expecting 6+/8 for it.

This was definately the hardest section of the exam for me. What did you guys and gals think of it?

SCREW YOU MANHATTAN PROJECT!!!!
This question took so goddamm long to answer properly. Is it just me or for all developments did you need to use 3-4 pages?

 

[roxy_chick]

I thought that it was aweful...it was just a stupid exam altogether...

Yeah...I took 4 as well...yuck...

Man I loved this option, it was so eassy, unlilke the core section, and you could write soo much for that manhattan project one as well

 

[darkwarrior2]

good stuff, no fermiosdfnsdfknjsdfns, or bsosdosdons, or hadronsdfjlhfsdkjnbsdfkjsds crap .

yeah, im glad they didnt do too much Bohr stuff

bohr shit is the easiest stuff.

oh well, whatever floats your boat...
(the one they did use was easy)
some of the core was stupid, until i ended up figuring it out

someone told me the mass of the rest proton should be more
than the velocity proton?

Whoever told you that should be shot
What do they think mass dilation means lol

haha, they got a teacher to do it
but i dont think that he told the question very well...

 

[richz]

easy q2q section, simliar to cssa trial just like chem, lol

 

[simonj2]

the decay stuff... i just guessed... i figured the Th one had to be less than 238... so i have a 1/238 chance of getting it right... can't remember what i did after that, but i'm pretty sure it involved failing... actually i didn't think i did too badly altogether, but that exam was a real shocker...

 

[sweet_chick]

part b) i dont think any amount of study on alpha and beta decay could help you there,

come on that was so easy all you have to know is the symbols and that all the numbers have to add up

i just hope the little v sign means neutrino

did u get 1.70 *10^-27 kg

and rest mass was 1.67*10^-27 kg

both 3 sig figs

 

[rama_v]

did u get 1.7 *10^-27 kg

and rest mass was 1.67*10^-27 kg

Yeah..my last one was 1.666 x 10^-27 im pretty sure

the first one also sounds familiar

both were 234 atomic mass, and for the second one it was 234 Pa

 

[serge]

Yeah..my last one was 1.666 x 10^-27

same here, cept i rounded it off to 3 sig fig

yeh i got 234 Pa aswell

 

[richz]

cool bananas

 

[simonj2]

thanks xrtzx, i got that bit wrong, but i got the same answer for the proton stuff...
