This is interesting, explains the mathematics behind Le Chatelier's principle. http://www.chemguide.co.uk/physical/equilibria/change.html#top Although you need to be familiar with equillibrium constants.

Le Chatelier's principle states: "If a chemical system at equilibrium experiences a change in concentration, temperature, volume, or total pressure, then the equilibrium shifts to partially counter-act the imposed change." (courtesy of Wikipedia :)) So simply, increasing the temperature will...

Yeah you mixed them up :uhhuh:

Here's hoping that Serena Williams doesn't win. :mad1: As to Guccione's chances ...if Guccione is in form and if Gonzales plays like he was playing against Baghdatis, then Guccione will win IMO. :lol: However, Gonzales was playing much better against Safin, but still not showing his true spark...

I was wondering the exact same thing. :)

Honestly, why are you still insistent on writing summaries for year 11 :confused: . I admire your enthusiasm but you'd be much better off mastering year 12 physics. You're wasting your time otherwise. As long as you were present in classes during year 11, that should be a solid enough...

That's quite a massive drop! :eek:

Use: GM/(4*pi^2) = r^3/T^2, where G = 6.67 * 10^-11 N m^2 kg^-2 and T (period) is measured in seconds.

Independantz, there exists no formula of which you quoted. The correct formula is simply the formula for orbital speed: v = (2*pi*r)/T which is derived from the formula for speed: s = d/t and it follows simply, where d = the circumference of the orbit (2*pi*r) and t is the time taken to complete...

He's probably working on volumes these holidays to get ahead, don't you think?

Thanks SS, thought so.

I'm pretty sure that we don't study the general theory of relativity in the physics HSC course, which deals with the curvature of the space-time continuum. Though correct me if I'm wrong, we haven't yet finished the Space module.

Think about when you're in a car, and then the driver suddenly brakes. You are pushed against the seatbelt. This is due to inertia, as stated by Newton in his first law of motion. You want to continue moving at the same velocity as you were before the car began to decelerate. The same principle...

QFT :rofl:

[/I] Gosford High, for one.

This might help: http://www.uac.edu.au/pubs/pdf/2007_table_A3.pdf

Thanks buchanan!

Evaluate: Make a judgement based on criteria ...This should help you. The textbook doesn't say because it doesn't matter as long as you're consistent. So yes, if you use millimetres as the rest length, then the relativistic length will also be in millimetres. Yeah sorry about the shortened...

the-derivative, it's actually spelled extension, not extenTion :lol: Sorry to be pedantic, but if you're taking ext. english, you probably should keep that in mind :D

If you're having trouble with (a) consider this: It seems (from the answers) that they want us to construct visually a cricket ball that has been pushed to a corner inside a cube. Now from what I can infer, you mean to say cm, not mm, and that the closest distance from the sides of the cube not...
