Thank you for taking your time and effort to get these up :D

Yeah and it the experiment that led to the discovery of the nucleus; but it can be related to this :)

re: HSC Chemistry Marathon Archive Shift to the left Adding acid or in this case H3O+ will increase the concentration of products (Since the concentration of H3O+ is increased) hence shifting equilibrium to the opposite side (i.e. The left)

What firm was it with if you don't mind me asking?

You're still in year 11 ... In year 12 physics we refer to conductors and insulators with reference to: "The Forbidden Energy Gap" "Valence Bands" "Conduction Bands" "Free Electrons Leaving Behind Positive Holes" etc etc

Mhhm I'd say leave Modern until after 2 unit if you know where you're going with it (i.e. If you've collated all the information you've needed and have your essay planned out)

Haha thanks :D Yeah I'm hoping my beast mode kicks in prior to trials (This will be my first opportunity to study for more than a week in advance for an exam so I'm interested to see how things will play out)

My apologies As you can see I haven't been getting much sleep :/

Bump for enigma!

Alternatively as integrand state cos(180 + x) = -cosx <-- This is because the cosine function is negative in the third quadrant 1 + cos(180 + 2x) = 1 + (-cos2x) < --- Using what I stated above = 1 - cos2x = 1 - (1 - 2sin^2x) OR = 1 - (2cos^2x - 1) OR = 1 - (cos^2x...

Use the form based on what the question is asking 1) If it is a prove question then look at the right hand side which will usually give you a hint as to what version of it you will have to apply. 2) If it is a simplification question then use the form that will be most convenient when...

Don't worry you'll get it easily :D At least you have your school rank to save you :P

You're one lucky guy I'd love to meet him one day His achievements just blow me away every time

*sees Janek Drevikovsky's name* *presses play without hesitation*

Haha how's it going to pull down your ATAR? Also to any past HSC'ers what mark for business should I aim for to ensure that my ATAR doesn't suffer?

Business Studies pls Anyone know any fun ways to go about studying it?

Mhhmm the school would get pretty sus as to why you brought it up that late (They may think that the report got forged and reprinted the exact same way you received it, etc.)

Example: In a clothes dryer the rotational mechanical energy is TRANSFORMED into heat energy. This heat energy is then TRANSFERRED to the water molecules in the clothes, hence drying the clothes.

I submit.
