<0> Look again. The second equation you wrote in http://img108.imageshack.us/img108/862/problemdw3.jpg is wrong.
<0> Start over from there. You want the component of W parallel to the incline. Take the incline to be the x axis.
<1> okay
<1> xtmdster, give me 1 sec
<2> if i have a sum of vectors, can i say that sum(A+B+C+D+E)= reference -E ?
<2> what value is the vector B=20 pointing right, on the x axis ?
<2> its just 20 ? no angle right
<3> anubiss, no angle
<4> xtmdster, are you there?
<5> hi
<6> hi
<2> absinisvacant: thanks
<2> abasinisvacant: thanks
<5> anyone seen Dark City?
<2> yup
<2> a long time ago
<2> is that the one with morphing cities ?
<5> to me, that movie shows me why people belief in christ and religions
<2> im out of business tonight, sorry
<5> yes, yes, the one with the aliens controlling the city
<5> I think most scientists are not religious because the "religions paradigm", shall we say is not fit them anymore
<5> if you break out of that paradigm, then you have movies like "matrix" and "dark city", where the themes are basically religious, but it is now a larger universe where it could be conceivable
<7> JabberWalkie: crappy connection?
<8> lol
<8> who wrote that question ?
<8> the one in the topic i mean
<7> JabberWalkie did
<8> heh
<8> i would ask if anyone ever got it wrong
<8> but i have spent too long teaching
<8> so i know that the answer would be something like "frequently"
<9> to a question of acceleration your answer would be 'frequently'?
<10> read the context my man
<8> i do believe that DanF_DrC was trying to troll me :P
<8> first time for everything i guess :P
<11> Manyfold: no i just chaned my ip
<11> *changed
<7> why did you change your ip?
<11> oh the resnet here has a bandwidth limit
<8> how did you do that without falling out of the channel ?
<11> andrewbryson: i did
<8> impressive :P
<11> if you go over your bandwith limit your connection gets slowed down to like 10kB/s
<8> lol\
<11> so i get around it by changing my mac address and reconnecting
<11> and it gives me a new ip
<10> thats odd, dont they just use packetshapers?
<11> dunno, dont care
<11> allz i know is i can change my ip whenever i want :)
<8> lol
<8> changing your mac address is cheating :P
<8> do they not have managed switches ?
<11> andrewbryson: i dont know :P
<8> i would guess not if you can get around it that easily :P
<11> :)
<11> whew, this experiment was a disaster...
<11> i can't even esimate my errors...
<11> seem to be around 400%...
<11> they are a little off...
<11> ill admit..
<8> not necessarily
<8> i mean was it an astrophysics experiment ?
<11> no
<8> that would be an excellent error then :P
<11> just an optics experiment
<8> hmmm
<8> can you claim that it was astrophysics ?
<11> i blame the pyrometer
<11> those things are hard to use
<8> lol
<11> i dont like instriments that rely on your judgement to get a good reading...
<11> *instruments
<11> and we should have taken response data closer to the helium lines
<7> JabberWalkie: which experiment?
<11> all in all a succussful experiment
<7> JabberWalkie: optics is EVIL
<10> http://antwrp.gsfc.nasa.gov/apod/ap070122.html
<11> Manyfold: http://www.physics.ubc.ca/~phys308/2007-Phys308Website/LabManual/Monochromator.pdf
<10> great pic of Comet Mcnaught
<11> no optics is neat
<11> even though we didn't get any decent data, we now know how to preform a better experiment :)
<7> JabberWalkie: the light from the source is white?
<7> JabberWalkie: what was your error for that linear measurement?
<11> Manyfold: oh the linear measurement is just to check if its linear
<11> and it was fairly linear
<11> except for high intensities
<7> :)
<11> and no it wasn't light
<11> white
<11> it was a tungsten lamp, but we had the emisivity curves
<11> so its ok
<7> what programs do you use to do analysis?
<11> well in 3 and a half hours i will be using matlab
<11> but for now i have Open office Calc, gnuplot, and mathematica
<8> lol
<8> mathematica > matlab generally speaking
<11> i want an nth order polynomial fit!
<8> pfft
<11> i can't do that in mathmatica.....ive tried :(
<7> we did something comparable using x-rays and a cristall as grating
<7> needless to say i thrashed the equipment
<11> :P
<7> the woman which suervised the experiment was furious
<11> is there somthing better than a pyrometer to measure the temperature with?
<7> :(
<8> sure
<8> just measure the emission spectrum
<8> you should be able to deduce the temperature from that
<11> god damn, it was invented in the 17 hundreds....
<7> pyrometer uses emission of light to determine temperature?
<11> Manyfold: no it compares the emmited light to a filiment in the telescope
<7> andrewbryson: i thaughzt you know nothing about physics?
<11> when they are the same intensity they are they same temp
<11> yea i know it ****s
<8> Manyfold: i thought you were 13
<8> :P
<7> i am 13 :)
<8> pmsl
<8> for 2 years now ? :P
<8> or is it 3 ?
<7> yeah i am onboard of a relativistic spacecraft
<8> nice
<8> is it called "earth" ?
<7> don't you see how redshifted i am
<7> :)
<8> maybe that is just the blood-lust :P
<11> Manyfold: then why arn't you terrably lagged?
<7> JabberWalkie: it's because i use tachyons to communicate
<11> anyways...
<7> so i type the answer before you type the qusetion
<8> hmmm
<8> that *would* explain your answers
<7> ?
<11> rolf
<8> :P
<7> andrewbryson: teachers ****
<11> hey I went to see a nobel laurate speak a few weeks ago
<8> wow
<8> is speaking considered a major achievement for laureates these days ?
<7> who was it and what did he say?
<11> Manyfold: oh it was Wiemann and he didn't say anything toooo interesting
<8> heh
<8> i went to a lecture by some field medal recipient a few years back
<8> he also did not say anything too interesting
<11> he is starting the Carl Wiemann learning enhancement reasearch project thinggy
<11> andrewbryson: well i did go and see Sir Roger Penrose a while back, that was intersting :)
<8> lol
<8> it would be
<8> he is generally regarded to be a good speaker
<11> he was telling us about his new theory
<8> did it involve extorting money from funding organisations ?
