Yeah i got P - Q, i thought the P was on top of Q

[BiG DaN]

heres my answers

Power
2. AB
3. 4 x 10^-3
4. 8 X 10^-5
5. B
6.D

These r just my answers

[We Want Peace.]

wasnt P on the top?>

it said through the square loop.
not the outside path.

[We Want Peace.]

R u sure?
I got Q1 BA.

[Nelle91]

Oh, i see, those tricky bastards lol

[onlyfknhuman]

i got ab too

and instead of 8v i got 9v i think

[hamtarofreak]

I got AB for Q1 too

2. AB
3. 4 x 10^-3
4. 8 X 10^-5
5. B
6. D
7 2.8V
8 C
9 1.6 x 10 ^-6
10 Q to P (think its wrong)
11 48W
12 8V
13 8A (dunno bout this)
14 400 turns
15 0.17

(I hope these are all right, because they're what I got too =P)

Heh, for the second question in Light and Matter I wrote about half a page on how mercury lamps emit light for some reason... :uglystupid2:

for that gangsta parallel circuit question the answer is 4.8 amps, you had to find the resistance of the whole circuit using 1/R = 1/3 + 1/3 so resistance of parallel lights bit was 1.5, plus wire resistance total of 1 gives R = 2.5, from Ohms V = IR, I = 12/2.5 = 4.8A 8-)

for Q1, how were the magnets arranged?

[onlyfknhuman]

MAO MY MANNN WHERE ARE U YOO

I think u have to seperate the resistance of globe and the wires. ( they are different )

Damn questions 12 and 13, i hate fountains so much now!! the answer was apparantly 9 volts, because you have to include the resistance of the bulb when finding the voltage.

my fuzzix teacher got 4.8 so i assume its right. U gotta add the resistances to find the overall current produced for the whole circuit, which happened to be the current for the point required. what did other people get?

THink 9V is actually the right ans.( Since the smartest guy( nerd? no offence)
 in our school got 9V..) so...yeah....doubt my 8 A now

[onlyfknhuman]

i 2nd that, its 9v
