I'm terrible at probability and I don't know how to go about answering this question! Can anyone help? The probability that a plant grows to maturity is 1/9. What is the least number of plants needed to have at least a 95% chance of one plant reaching maturity? Thank you :)

Cool, I get it now :) Thank you!!

So can we say that after the first electron travels through, the lattice distorts and creates a positive region which attracts the second electron. The two electrons then swap phonons to form a Cooper pair to keep them moving through the lattice together, past this positive region and unimpeded...

I don't know what phonons are or how they come into an explanation of the BCS theory but I know you should include them in your explanation. Can anyone help me understand them?! Thanks! :)

True, but in the context of the MM experiment, you cannot say disproved because it had a null result.

No, just making an additional point that the OP is sure to never state that it 'disproved' the aether.

This. It didn't disprove it, it just cast doubt upon it.

I know the feeling! Do you feel your fairly prepared though?

Its ok. Been procrastinating a fair bit the last few days so hopefully I can snap out of it but I can't wait for it to all just be over! How about you? :)

For 2U, pretty much everything comes up in one form or another because the HSC is essentially the same, just a little more difficult, and a few extra topics. So all your differentiation, trig, quadratics, etc. For 3U, parametrics always comes up, so does all your double angle and t formulas...

Wooooo!

Sorry to bring up an old thread but I have just recently come across this. Does someone know what we can do about these types of questions? In the 2005 question, the answer should be B cause though smaller eddy currents are induced there will still be some braking, not NO breaking. And in 2011...

I ended up putting advanced as my first preference and medical as my second but thank you so much for your response!!

Hi :) Looking at the units UNSW offers, I think I'd prefer to go there but I don't know which is better - going with medical sci or advanced sci. If I did pick advanced, I would do pretty much all the same units (maybe biochemistry or pathology or something along those lines) as I would in...

What if you don't want to transfer into medicine and you just want to stick with medical science, would medical science be a good degree to get you into work with like a pathology company or a hospital laboratory or something like that?

Someone please help! I'm so confused. I know acidic conditions accelerate the rate of corrosion but I don't quite understand why. Is it because of this reaction: Fe(s) + 2H+ -> Fe2+ + H2(g) And because you have Fe2+, it will go on to react with something else and hence has corroded. Or...

haha that's cute. And true, we've all got to start somewhere :D Speaking of that, I should get back to studying :\ Night Spi :)

Sounds great! Is that going to be your post-HSC present?

Aw I'm sorry. Well, on the upside, you got to save a lot of money!

haha I wish. I'm sure you'll be picking up all the ladies at your formal Spi :D
