The solution for question 10 is A for the the following reasons: 1) Initially when the switch is closed for a short time, a magnetic field is created extending into the secondary coil. As the field is not changing, then the only time an emf is induced in the secondary coil is when it first cuts...

retrofiring? Don't worry guys, i don't think you were meant to address every single force occuring because then that would be a waste of time. If you did the implications of the forces, e.g. g-forces => leads to unconsciousness blah blah and stuff like that you should still get marks for it...

If you apply the right hand palm rule to question 9: Palm in direction of motion of the disc (palm facing away from you) Fingers going from left to right (joint to tips) .: Your thumb faces up and the conventional current flows through X first and then through to Y... so i guess it's C*

Even if you apply the formula for EMF on this generator and then graph it you should get a sinusoidal pattern because there is nothing in that diagram to tell me that the current is being reversed every half turn. EDIT: oops i think ur right for 10, because once the current is turned off the...

Luckily i wrote mine down on the question sheet aswell :p This is what i got: 1. C [the values of g changes due to lithosphere density etc.] 2. B [A mass in circular motion experiences tangential velocity] 3. D 4. B [Acceleration on a projectile is constant at 9.8m/s2] 5. D [Using Keppler's...

I did it this way.... ΔEp=Ep(final)-Ep(initial) =-(G.m1m2)/R1 + (G.m1m2)/R2 =G.m1m2)(1/R2 -1/R1) Then you would substitute the values they gave you to move from 10000km to 20000km and you would find m1m2 You would then do apply the same formula...

wtf was up with that "bone" scan image....

If the angle is taken from where the plane intercepts the magnetic lines of flux then the formula is BAsin @ not cos@. This is because as @ approaches 90 degrees, cos @ approaches 0, contradicting the statement that magnetic flux density is greatest when it is perpendicular to the lines of flux.

if u mentioned power struggle and related this to Lear you should be able to get some marks. the rubric also required you to talk about context and the only way i think you could have talked about that is if you went into interpretations and the portrayal of lear in those interpretations.

which uni would be better for science and why?

Oh god how i miss 13 hour sleep ins :(

i don't think you need to know that :confused: just basic information about the productions...

I have never ever seen an interview transcript required for module A and i would die if that happened this year :(

Ok, whats the syntax for including examples in essays? Is it just e.g. and then blah blah blah or is there another way?

wouldn't you do something like this... Lim (cos[x]-1)/x -------> Lim(cos[x]/x - 1/x) as x-> 0, cos[x]-> 1, 1/x -> inf .: Lim (cos[x]-1)/x ------->Lim(inf. - inf.) ------->0 im not sure if that makes any sense though :p

omg omg omg omg omg omg OMG!

fuck that im gonna ditch AOS study and do paper 2

im okay for the AoS i guess... but so not ready for paper 2... english scares me the most :(

yeah well its the only one thats compulsory so u can't exactly do that... unless you want to stuff up

ahahahaha wat a champ
