Anyone ready for it?

I know I'm not, haven't learnt anything all year thanks to some mediocre teaching.

 

[raniaaa]

should be ready by 1:30 tomorrow
although for motors and generators i'm definately screwed

 

[astroe]

I've woken up now to study my ass off until 12:30.
Arrrghhh. LOL.

 

[clonestar]

Good luck guys.

I believe it's actually quite a reasonable and straight-forward test.

i.e. if you have studied of course....

 

[harry4]

can someone explain to me how a loudpeaker works?

cos i really don't understand it like i do the galvanometer

There's a nice explanation here

I wish everyone good luck. I'm just hoping the questions are nice and they don't ask me anything i don't know

 

[shady145]

how was it?

 

[kaz1]

Test was alright except for the question about the chinese astronauts so I bsed something about g-forces.

 

[AnandDNA]

what else could you talk about in the question. I wrote g-forces and communication problems once the rocket enters the van allen radiation belt

 

[Chrissiieee]

lol tautikans were they called?

I found it easier than i thought it would be
although i still screwed up

 

[annabackwards]

I thought the exam was super easy... but i may have misread the last question in the graph question. I thought it asked how to work out the direction of the force without calculations but apparently that wasn't it >.>

 

[Bernie Mac]

lolz i died on the ac generators impact on the 20th century part....wrote too little

 

[hereyes]

^
yep. that killed me too. What was with all the transformer questions?
aha yeh and chinese astronauts. taikonauts? or something.
btw what was happening to the gpe


that's not right at all..is it?:mad1:

 

[astroe]

Eh I'm not so happy about how I went,
I finished everything but I felt that it wasn't up to what I had hoped.

EDIT: I DIDN'T SAY SHIT, YOU GOT NOTHING ON MEH.

 

[annabackwards]

Everyone should just be happy that it's over ^^

 

[astroe]

OH no, I talked about a question and I noticed the Admin's edit just now D:

Don't ban me please!
LOL @ Anna, you posted after it got editted, ban her for collusion.

 

[thisnameistaken]

I didnt know what to leave out for that 6 marks black body + photoelectric effect question, so i just filled the whole page with small writing

Way to throw me under a bus. I'll get you back lol XD

btw what was happening to the gravitational potential energy during first stage of launch?

&& what was the issue with the launch for the taikonauts?
said something about g-forces too...and needing more fuel/energy in order to accelerate and travel to such altitudes within a short period of time.

that's not right at all..is it?:mad1:

I wrote gravatational potential energy is increasing during launch as the rocket is losing mass from fuel consumption and thus losing kinetic energy. From Law of conservation of energy (state definition here) the rocket must be gaining gravatational potenial enegy as it moves upwards

 

[tanna]

I thought it was hard but that's just cos i didn't study much (worst 2 units)
