Vs/Vp=Ns/Np therefore Vs=Vp*Ns/Np effectively as I understood it, the question was asking you to change Np by moving the primary coil in and out, so a lower Np would cause a bigger Voltage in the second. That's what I put. No idea if this is how you go about it. Has anyone tested it?

So many WORDS! Fucking words. I can't express myself properly. There was at least five 6 marks questions if I recall? Not good, not good at all.

Sure, both the initial atom and the product atoms have binding energy, but the critical thing is binding energy PER NUCLEON. In a fission reaction, atoms larger than iron (such as uranium) split into two or more product atoms, each with more binding energy per nucleon. Therefore more binding...

Wait, I thought the ions were the lattice - or does the lattice here refer only to the grid-like structure of their arrangement? Thomson's cathode ray tube had enough air removed in order to visually observe deflection of the cathode ray by electric fields. The anode in thomson's tube was...

easiest way to think of it is that the change from 0 flux to any flux is pretty much infinite. then you find the place with 0 flux (ie parallel to the field) and voila, that's the place with highest emf.

For question 19, would you talk about the slingshot effect and how 'using physics' can save time and resources? Because isn't that essentially what they were doing? As obvious as it is, I wouldn't have thought about Newton's Laws. Lame. I just saw Newton as emblematic of physics in general.

2003 Multiple choice question 9 2006 Multiple choice question 7 (this one's a bitch) EDIT: These are for force though, not for torque, but the principle still applies. Check the angle!

There's no point in remembering cos θ or sin θ if you don't know what angle θ stands for. In order to simplify our equations we always make θ the angle between the current and the magnetic field - watch out, sometimes they give you another related angle, subbing that into the equation will give...

Also the fact that one uses DC and the other, AC :) If it's worth more marks remember to explain why slip rings or split rings are used (hint: torque) And it'll probably be a compare question, so look at similarities too.

One of the readings my teacher explained was that Kubla Khan is a visual metaphor for the human mind and imagination itself. The caverns measureless to man = unlimited potential, fertile ground = receptive mind, torrent of water = sudden stream of thought, sacred river = worldview (that last...

Nice points kinkybell! Hope you don't mind me stealing them (even though you did it last year and probably don't care now...) Also like to add that ESoSM is also an imaginative journey on the composer's part, starting with a 'what if' and continuing from there, showing the impacts on humanity...

Hey, I just read that article! I'm interested to know how you're going to interpret that within the context of journeys. As for myself, I think I might be doing that article in the guide last week (I think) about new inventors and the spirit of the inventor.
