As a side note, here is an excellent site that may help all those learning relativity http://www.phys.unsw.edu.au/einsteinlight/

From what you've written, they are basically asking you to - create a sample database. - talk about the processes used to create the database. For example: collection of the data - where did u get the data for the table, how did u attain it etc. Do this for all the processes. - create a...

They are talking about the erd (entity relationship diagram). Its similar to the figure in access when u design your relational database.

Emf is an unfortunate term as it is not really a force. It refers to a potential difference in volts in a conductor. In modern terms, the emf of a battery is the maximum possible voltage that the battery can provide between its terminals. When a conductor is moved through a magnetic field...

Re: So its the holidays before trials... Its about 4 weeks b4 your first english exam.

It also depends on whether you are referring to a river or a still lake.

A good way to learn is to get a graphing program (many free ones are available) and just get it to draw different graphs. Then you can fiddle around and see what altering a variable does.

Yeah there was a fair bit of writing. At least it was about physics though, unlike the HSC (which was about society). In that regard I don't mind it. Tonnes of ppl were at the Upper tea :p Are you guys doing Higher 1B? Which lecture/lab?

Success One answers are excellent but they are far far too detailed. Answers which half much less than their answers would still score full marks in exam situations (even the book says this). However they are a good guide as to what it is you should be writing, and how to set up your responses...

lol. can u remember your seat. I have a feeling u may have been the person sitting to the right/just in front of me. Anyway, I am ruing having done question 4 b4 they made the correction. I had to do half of it again :(

The test was weird. Many worded questions, but Electricity and Mag. was generally pretty good. Test 1R was difficult. I attempted it after finishing Test 2 completely, and I almost managed to finish it, just left out half of a question. btw, were you in Level 4 at randwick for the exam?

They are just saying V = 240 volts, which is the voltage used in Australian homes.

lol. I love how the same topic is discussed for weeks and weeks when every1 else has forgotten about it.

The exam was ok. I was pushed for time, and I knew how to do all but 3 of the questions (1 of which i figured out, but ran out of time). I just hope I made no silly errors in the matrix questions, some of the numbers became messy...

This is no longer in the ideas to implementation section, but it is in quanta to quarks. The formula you need is de broglie's formula, lambda = h / mv

Just do well at school in case you wish to do a degree at uni. Good marks/UAI are a good backup. And like Templar said, you have until January to decide what course you want to do.

Seriously guys, how hard is it to make up a scientist on the spot. Just say its a relative of yours if your teacher asks. It might even be true :D I didn't even study for this dotpoint when I did the HSC. Consider yourself extremely unlucky if you get examined on it in the HSC... :D

In that case, just think of the advantages semiconductors have over traditional valves. For example they are much smaller, they use far less power, they are more reliable (they dont have any fragile heating filmanets), they operate at room temperature etc. Check the resources for some good...
