When they mean energy transformations you could do something like Electrical energy->Sound energy (e.g. in a radio) or Electrical energy-> Kinetic Eneregy + Heat Energy + Sound ENergy (e.g. washing machine)

Don't worry. We are all in the same position :D

If you have trouble try posting in your lab discussions forum on web ct. Thats the first place to start :) Well for the unknown cell flowchart, just go through and write done what stain identifies what, and research and write down the differences between procaryotes and eucaryotes. Then, as a...

hmm I seee..But the integral of ex2 is not elementary is it? (And I have certainly seen this question before, somewhere..) Anyway I think my question has been answered. Thanks guys.

I have seen in an exam question, integrate xex2 ..I can't remember where I saw it though.

I have noticed in many textbooks people have written questions such as Integrate e-x2..And then the answer is supposed to be -2xe-x2..But is that even correct? The reason I ask is that when I do this on maple, I get things that involve the "Erfi" function, and I have read in books that there...

Yeah the notes should techincally say "5.2 to 7.2 degrees to the horizontal" as well.

Oh Sorry..Umm I'm not sure of another way...

(Cos3@) can be integrated by using the complex identity Cos@ = e@ + [e-i@][/ 2 where ei@=Cos@ + iSin@ let z = ei@ 1/z = e-i@ ((z + (1/z))/2)3 = Cos3@ Go from there

I think you must remember that when they mean the universe is expanding, that means that space is expanding. An important point to remember is that the "Big bang" was not an explosion in space, but an explosion of space.

Absolutely. Joe is in fact our lecturer for physics (PHYS1131) and he really knows his stuff. I highly reccomend his site.

Please dont get us started on this...lol http://community.boredofstudies.org/264/motors-generators/68679/quick-question-lenzs-law.html?highlight=lenz+law

Two years ago no one got over 90 at my school. Last year we had 7 people get over 90 and I got 99.35 hmmm

Not at all. It matters what teachers you have and how much work you put in.

Well eddy currents are simply circular currents that arise from the effects of Lenz's Law. Try this link. Chances are that your questions have already been answered - just use the search feature on this forum :)...

Here's a list of essay questions my friend and I compiled while doing Modern History a couple of years ago. Some may/may not be relevant to what you are currently studying, so just omit those ones. WW! 1. Account for the differing conditions in the trenches on the Western Front. 2. Explain...

do the first and last question of each exercise

I dont think u receive any emails. But it will be in the news section on MyUNSW after you log in. You can view your fee statement there too.

It should be un ur unimail account...they told us to buy the book required during this semester + cd, it costs 15 bucks at the BEES office.
