I'd probably guess Manhattan project (If you're doing Q2Q) as i've only seen it
once through in the past HSC exams, but I hope it's Pauli and Heisenberg's contribution..
No probs. Also if you need any help in 4U maths i'll be happy to help. I'm about to tutor people after I finish HSC so you can add my msn or just pm me (:
Did anyone talk about GENETICS? or just focused on environment?
I related genetics with mendel and artificial pollination created different phenotypes, short, long, round, wrinkled, etc..
It depends on how well your answer is, if you mentioned all those and filled up the lines you should be getting a decent mark. I did hydrangeas and growth as well. I also did mendel and just general comments on environment such as sun affecting our skin,etc.
I'd say a decent mark 6-8?
I'd recommend you dropping a subject ninepercent. When I did 14 units at the very beginning I was lucky to drop 2 units before half yearlies then another 2 units before trials. It was hell and I would've died doing 4U because I was mostly doing 4U (4U you need a lot of time).
Use this formula derived from JJ thompson
R = mv/qbsin(theta)
Where theta = 90 (perpendicular)
Sub in values and you can get radius :)
Derivation: F = mv^2/r = qvbsin(theta)
rearranging to make R the subject R ->
mv^2/qvbsin(theta) =...
Uhm.. unlikely. But the lines are an indication of how concise your answer should be...so going overboard is unnecessary but don't think you'll get deducted for it.
Re: What will be this years band 6 be for bio
Lol agreed. The guy sitting next to me just went to sleep for the whole exam...
I hope I can get band 6.. gaah.. Multiple choice probably screwed me over
No because its "dry" remember, if it opens up it will transpire at the speed of light and therefore die. It doesn't want to transpire more water -_- it uses water for photosynthesis. It wants to close it so that it keeps cool and theres is less water loss during the hottest part of the day.
