We have about 25 at the moment, but that number will probably halve by the end of term one

Can anyone recommend a really good and interesting book on the Great War or the Russian Revolution that I can have a crack at reading these holidays for the Modern History Course? Anything that isn't longer than like 400 pages that i can finish by the end of the holidays.

I'm doing History Extension this year and we've been told to just read around the subject for the holidays and to have our question and proposal done by the end of term one, so we can write the essay in term two

Also, in some marking criteria (I think it was CSSA) they wanted you to write about how today, humans are not capable of reaching the speeds where the effects of relativity will be significant, but it is something for the future (they gave the example of the light sail). I think that's only if...

You gave me a good idea for an ending because I was struggling

Thanks for the feedback, that's a good idea

Could someone give me some advice on my basic idea, because i think it may be to cliche. It's about an arab man walking through an airport, and is stopped at every security point, and has his bag searched several times. It's based on the quote from last year's HSC: "Human beings, like...

Also if the rocket's launch corresponds with the launch window: if the direction of the launch corresponds with the direction of the desired heading then the rocket can acheive an even larger velocity boost

They asked a question on that in this year's HSC and i think that they only required simple conversions like the one's you've written

It just means there's less strain and less load on the bearings, so I think it makes it safer and easier to operate?

I don't think its been tested in over a decade, but that means they may ask a question on it this year...

Does anyone know any good poems for belonging that I could use as a related text?

Looking For Alibrandi or Edward Scissorhands?

Yeah ur right thats my bad GPE = -GMm/r, not -GMm/r^2

The escape velocity of an object is acheived when it has a net energy of zero, so when it's kinetic energy is equal and opposite to its gravitational potential energy, so equating GMm/r^2 and 1/2(mv^2) will give the escape velocity

I was just wondering what other people thought of using "Crocodile Dundee" as a related for belonging, because it has some half-decent ideas in it, but some people who i've spoken to think that it may be too simplistic or generic.

Are you sure about Q11 of the multiple choice?

The Principle of Relativity is only Galileo's Theory, though. It has nothing to do with Einstein's Theory of Special Relativity

I got 5.9 x 10^-8 (s) as well for the projectile motion question as well doing pretty much what you did
