do you mean in the forums?

I've been able to access the biki, but just not able to save changes.

torque is a turning force. torque = Force x perpendicular distance. in terms of a coil, τ = nBIAcosθ Where; τ = torque (Nm) n = number of coils B = magnetic field strength (T) I = current (A) A = area of coil (m2) θ = angle This result can be derived from the 1st definition...

mods do read this. improving the resources system to make it easier to find what you want is on my todo list. :)

hmm.. not exactly sure, but i would recommend you take a look at this video, published by TALE DET.

I've been reading the NSW Department of Education and Training's, Information for Newly Appointed Teachers, available here. Here are just some of the things which were a bit unusual, interesting, or out of the ordinary. Note that this only applies to NSW Government schools. According to this...

err, its still slow...

You can buy copper wire at any electronics store, such as Dick Smith Electronics...

I'm not exactly sure what you are asking. You want to change your subjects for SAM. But arn't your Preliminary ones the same as your HSC ones, with the exception of dropping a subject, in which case i think you can just leave your mark as zero and it won't affect the calculations, or addition of...

take a look at this thread.

I never learnt about them till Industrial Chemistry Option.

Must be your computer, it works fine for me. Just update your Adobe Reader, or try on another computer.

Trebla, I know that this was in the English comments for a specific question, however I still believe that the same rule should apply to all examinations conducted by the Board of Studies, as all the examinations are subject to the same policy document, and no where in this policy document that...

There is only a limited number of ways to answer a 2 mark question. Chances are that more than two people will have the same bloody answer, but you are not going to say that those two people plagarised. Even for 7 mark questions, if the BOS want's to ask questions that are so predictable that...

Wow, thats a big move for the Board of Studies!!! But I totally dissagree with it! Plagaism should not apply to examinaitons. The Board of Studies needs to produce policies and clearer information on what they do not allow in the exam. This is rediculous. I am going to write to the Board, untill...

You don't really need to know parabolic for HSC physics, but you should know it from year 10 maths. Its just y=x^2.

He is right, that lecture sequence will not be run this year. You must pick a different school's ENGG1000 lecture sequence. I don't think it matter's what you do, but I do think that ENGG1000 is compulsory.

Wow, that's an excellent answer.

I suggest that you take a look at my notes, in particular pages 5-6, 12 (accuracy is on pages 2-3). In addition I suggest that you read the following articles which were published in Curriculum Support for teaching in Science 7-12. Which is a publication aimed at teachers, distributed to all...

If you say y is directly proportional to x, then that means that y∝x, hence y=kx where k is some constant. If you plot y=kx, (where k is const) you get a straight line, hence we say that the relationship is linear. Remember that you can replace the proportional sign, ∝, with =k where k is...
