Uhh, would you mind recapping on how to do that for me?

shit man you not serious !! =S
okay wat equations we need to know for tht ?i

Using a stretched rubber cord;
1) stretch a rubber cord attached to a vibration generator and clamp its end
2) starting at a low value, slowly increase the freq. of the vibrator generator
3) observe the stationary wave pattern of the fundamental freq.
4) Measure the distance between the 2 nodes and double it to get wavelength
5) Use equation v=fλ to calculate the speed of waves on the rubber cord
6) continue to increase the frequency slowly until the next stationary wave pattern is produced

We were told the examiners prefer it differently, my teacher went to a seminar or something, and told us that they wanted us to do it the way I showed.

lol my sir said the samething lol he went to a seminar and heard it

 

[¦HaLo¦]

i see ur not tensed at all

Then what do we do? Just the way you want to do it I guess, if they are giving us mixed messages, they can't expect everyone to do it the same way.

 

[¦HaLo¦]

ahahhaha ! man me neither ! everyone i asked gave me a complete different way ! =p
am thinkin of givin up on it , this mark wont make much difference =p !

it will man every single mark counts unless u dont care about losing a A by 1 mark :O

Cheers, I thought it was that, but then I got confused, thank you very much for clearing that up,

Best of luck today ^^

i am really tensed actually.

yw
thanku and good luck to u too

Eh, you're completely right about the one mark think, I mean the multiple choice part counts for 12.5%
And if we get a big 12 mark planning question that's 30% of our whole paper!

So yeah, one mark can make all the difference in this case

man no man ! a don think ide b that close to a ! lol =p

hey thank you ! =p
but theres somethin bout hangin weights i remember ??

 

[¦HaLo¦]

man no man ! a don think ide b that close to a ! lol =p

who knows man wat if the examiner prefers u more than us :O (FAVOURITISM!!)

 

[xIshtar]

man no man ! a don think ide b that close to a ! lol =p

Have faith in yourself, and good things will happen
It's okay, I'm pretty sure everyone here is near enough scared out of their minds.

Thats another method, the way that was explained is a simpler one I think

ikr god its in 2 hrs

not as far as i noe
maybe its some other practical and besides there are many different ways of showing standing waves.

ahahah ya man sure plus the way ma paper would look !! he soo would lol =p
