89 for Standard English One pitiful mark :'(

I agree with your idea of extreme scaling! That exam was heaps hard to my memory, and I didn't even expect above 80, but it turned out I got 90 on the dot I wonder what happened :O

Yeah I get where you're coming from, but maybe it's a bit oversimplified for my liking. I heart 3U projectiles :party:.

+1 It makes much more sense with 3 Unit integration to solve projectiles. All the Physics projectile formulas never made sense to me :(

Yes! That's what I wrote too (Although I mentioned removing more products than reactants because the Reactants decreased after the change and the products increased) Pressure can't affect it because it's 1:1:1 mole ratio. Let's hope me and you are right on this one ;)

Yes, that's right. And the third change in graph involved removal of both products and reactants (mostly products), causing the equilibrium to shift to the right, so reactants dropped and products increased.

That's a more general question. You would have to discuss Reliability and Validity. Reliability: How many sources of information did you compare with? Validity: What kind of source did you get your information from? (e.g. a blog would contain invalid information (to an extent it may be...

That's a rather general dot point. Think of where electricity is used in modern day society. (Lighting, computers, washing machines, everywhere!) Since it talks about dependency, talk about what would happen if there was no electricity (e.g. blackout / total darkness). (On a side note...

Made a mistake, my apologies.

Re: Yr 12 physic help!! I don't know about question 1, but here's my attempts at question 2 and 3. 2) Explain how transmission line are: - insulated from supporting structures. Transmission lines generally carry high amounts of voltage, and since metallic structures are cheaper than...

That was not even the slightest bit funny.

Torque = nBIAcosθ n = 80 B = 0.25 I = 0.060 A = 0.0016 θ = 0 = 80 x 0.25 x 0.060 x 0.0016 x 1 = 1.92x10^-3 Nm Note that the area is given, therefore you don't need to square it again. And you should convert the area into m^2.

Thanks again. I think the OP would have been better off doing it himself -.- At this rate, I've created more errors than him.

Oh sorry, I obviously read a misleading quote. Thanks for the heads up.

I understand the above working out .. But where abouts did the 4 come from? Because every line there seems to be a 4x Edit: I guess it's just a simplification, thanks for the answer.

Force acting on a current carrying conductor is given by: F=nBIL\sin\theta B = 0.4T I = 1.6A L = 0.05 n = 250 \theta = 90 Note that \sin 90 \neq 0 Question a) F = 250 x 0.4 x 1.6 x 0.05 x sin90 F = 8N Question b) F = 0 Because the current carrying conductor is parallel to the magnetic...

There's this question that I dunno how to tackle :| A person throws a cricket ball so that it's path is given by x=20t, y=16t(3-t), where x and y are measured in metres and t in seconds. Find the: a) Initial velocity and the initial angle of projection. b) Find the greatest height reached. c)...

Thanks a bunch! Credit to you both :) Case closed. (Or so I think).

Yeah, I found a chart on Wiki. Tells me about the radians and stuff. Just to let you know, It's positive in the fist quadrant too :D EDIT: Isn't the answer pi/3 and 5pi/3 ?

No no, apart from the calculator method, There was another way to do it. And I want that method ;).
