Guess the questions on Exam 2 !!

[rox-n-bones]

ok this may seem extremely lame but it may help some people study what they don't already know...and how exciting will it be if we guessed correctly

ok i'll start with an easy 1...i think they're going to ask about the force on a coil when it's parrallel AND perpendicular to the magnetic feild. costing us approx 2-4 marks

anymore guesses/suggestions?

[Galelleo]

well there will definately be a question trying to test us on whether we know difference between ac/dc generators and motors.

also, i reckon there will be a question abuot Bafflers (on speakers), if not bafflers, than about gap width on tweeters/subwoofers (diffraction:l/w)

havent really thought about it

[Matt89]

I'm predicting there will be a question asking you to define what a commutator is

I haven't started hardcode studying yet, I will starting tomorrow now english is out of the way, by friday/saturday I will predict stuff

I predicted a question on english language today right xD Except I'm suprised how directly they worded it, was thinking it'd be tied up in a longer question. Oh well.

From what I remember from U3, physics is hard to predict relative to chem. I'll try anyway.

Physics unit 4 is more predictable than unit 3. In unit 3 they could create new sort of mechanics/newtonian physics questions, doesn't really happen with unit 4...

yeah im not starting studying properly for physics (minus what i did pre-swotvac) until after tomorrow + psychology.

Physics is usually your run of the mill questions, similar each year with values change. Theres only so much they can test you on, and each of the concepts are kind of linked (for each topic), so its hard not to know what youre going to have to do in the exam.

i guess they will put an induced emf question, similar to last years 2cm^2 moving coil through magnetic field.

i've studied, but not enough i have 4 exams in the next 7 days, soo hopefully i can stop procrastinating.

**counting methods 1,2 as seperate exams**

i guess they will put an induced emf question, similar to last years 2cm^2 moving coil through magnetic field.

definatly be a repeat of a similar question, was done terribly last year

^yeah thats what i thought.

what was the cutoff mark for A+ last year?  most likely higher than the unit exam 3 i assume.

81/90 was the cut off, which is much higher than the Exam 1 2006 cutoff
