thats pretty high

I guess that makes sense. I dont get this bit, "The energy which is contained in the light exites electrons in the nebula". Im assuming that a nebula emmits light. So at what point between the observer and the nebula is the energy lost in the photons ? ?

Could someone please explain the emission spectrum...

Trig parallax is where you measure the parallax shift of a star by observing it 6 months apart against a background of stars, then using the parallax shift (the angle P), and the distance between the sun and earth as 1 AU, you can use trigonometry to find the distance. You go Sin p = earths...

LOL, thats really funny.

I have my own notes I wrote a few weeks ago. About 10 pages for each of the four topics. I printed out the 4 syllabuses and made notes on each dot point. Dont use other peoples. Make your own. It is so fucking awsome, because you learn the work soooo much better.

yeh. thanks.

I guess that could be right.

So i would just talk about that when the flux across the coil is max, the coil is 90 degrees to B. And when the angle is 90, cos90 = 0 (torque = 0). Bu I dont see how you can get 4 marks out of it. And also, is it correct to say that the when the perpendicular distance between the coil and...

Can someone please gimme a good response to a question like this - Explain why the torque on a current loop in a magnetic field is zero when the magnetic flux through the coil is at a max. I pretty much know it, but cant give a good response and get full marks. So could someone just post a...

So, a gene is a 3-base code sequence for a particular characteristic, and an allele are the alternatives for a particular characteristic. A person can have blue eye gene. The alleles are green, black, white, blah blah..........Is that correct ? ? ?

I just assumed differential was another way of say to differentiate. But i reckon that to differeniate, find the derivative, and find differential is 'kinda' similar. Like y=2x differentiated is 2 the derivative is 2 but if they were gonna use differential, that answer would be dy/dx=2. But...

ohh thanks Xayma. But why exactly was it done that way ? ? Can you do it this way - differentiated would be n(1.1)^(n-1) ? ?? ? ?

ok, the questions answer - working out, blah blah. Then is goes (NB d(1.1)^n / dn = In(1.1).(1.1)^n) it wants this to be differentiated...........-810 000(1.1)^n there answer to it is -810 000 In (1.1).(1.1)^n I thought that (1.1)^n differentiated would be n(1.1)^(n-1)... I dont...

basically, the differential of (1.1) to the power n = In(1.1).(1.1)^n i dont get it ?

cool thanks heaps.

Can someone please tell me how you integrate this - (4 - x^2)^1/2 thanks.

wow thanks. Its not like your replies actually effected my decisions, but its still cool to know the shit you guys do. I put mechatronics first, then mechanical and then electrical, all at sydney. I am happy to get any of them, and the UAI's range from 91 to 79, so yeh i should get into one...

oh god, that was hot. I didnt see her sing but i saw just when she finished her song and was listening to the judges. Maybe there are pictures on the net somewhere if you wanna see her.

oh man, you guys are doing alot of past papers. Ive probably done bout 4. I gotta start studying like crazy for all my subjects. fuck shit !!!
