hey mao, i believe you did question 10 incorrectly for electronics.
you just mis-read the value of the resistor at 25 degrees.

[simplicity123]

same, I think you read wrongly off the graph. Rtherm at 25degrees = 500ohms, you wrote 1250ohms instead xD

Yea just from memory i'm pretty sure i got 1000 ohms for the variable resistor on question 10

[TrueTears]

The answer is 1000 ohms

The only things I messed up on were labeling the stupid arrows on the stupid "insert arrow showing the forces" questions grrrr, and one of the structures questions.. but apart from that.. YAYAYAYAYAYAYAYAYAYAYAYAYAY!!! and now to not study for chem! guitar hero awaits me..

*facepalm*
I changed my answer in the apparent weight thing from 480 to 720 cos I thought I got the formula wrong. fail

Otherwise HOORAY PHYSICS. easy exam

[kurrymuncher]

[TonyHem]

Anyone know when we get our grades back from vcaa? ( letter grades)

[dejan91]

I'm concerned. So many people claiming high scores...is that just because of the intellect of the people on this forum is wayyyy above average, or did the rest of VIC find it easy too?

And Tonyhem, apparently around August.

[mano91]

for the apparent weight question. i wrote 720. how many marks would i lose?
and also in the modulation question, i got 1 right.
is that a half mark?
