Uhh, would you mind recapping on how to do that for me?
Using a stretched rubber cord;shit man you not serious !! =S
okay wat equations we need to know for tht ?i
lol my sir said the samething lol he went to a seminar and heard itWe 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.
i see ur not tensed at all
lol my sir said the samething lol he went to a seminar and heard it
it will man every single mark counts unless u dont care about losing a A by 1 mark :Oahahhaha ! 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 !
ikr y dont they make there mindsThen 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.
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
i am really tensed actually.i see ur not tensed at all
hahai am really tensed actually.
ywCheers, I thought it was that, but then I got confused, thank you very much for clearing that up,
Best of luck today ^^
ikr y dont they make there minds
man no man ! a don think ide b that close to a ! lol =pit will man every single mark counts unless u dont care about losing a A by 1 mark :O

who knows man wat if the examiner prefers u more than us :O (FAVOURITISM!!)man no man ! a don think ide b that close to a ! lol =p
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 ??
ikr god its in 2 hrsHave 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.
not as far as i noehey thank you ! =p
but theres somethin bout hangin weights i remember ??
ahahah ya man sure plus the way ma paper would look !! he soo would lol =pwho knows man wat if the examiner prefers u more than us :O (FAVOURITISM!!)
haha ya i do hope so =p !Have faith in yourself, and good things will happen
