jia lat !! i..my.. graph is straight de lei.. hai no hope liao -

mine is like almost perfect curve..but miss 1point.. but got cut origin
-
so the correct answer is what? the curve touches all the point or???Originally posted by Sienx:mine is like almost perfect curve..but miss 1point.. but got cut origin -
Initially i dont know what the hell i am supposed to do for physic, but i manage to know later on... Was on Shift 4, damn, wasted 1.30 hour waiting...
So what are the 2 ways to improve the experiment?
i wrote - increase the range of angles
- provide more pins (which i think it's wrong) -
my curve misses the 1st point onlyOriginally posted by felirox:so the correct answer is what? the curve touches all the point or??? -
eh. my curve touch all the points leh.
-
same.... =SOriginally posted by LordIcarus:eh. my curve touch all the points leh. -
hmm my curve miss 1 point.. i think its the 3rd yep..
-
by the way, it's impossible to miss the first point. it's 0.
-
yeah yeah
-
my 1st point as in the one after zeroOriginally posted by LordIcarus:by the way, it's impossible to miss the first point. it's 0. -
my apologies everyone.
wrong information has been given.
the correct one is, no chloride is present.
the substance x, is zinc carbonate. -
heng i bio..not chem or i die btw..todae bio also not pratical los...examine things nia
-
So what is the correct answer?
Mine was completely screwed up, i did the chem part twice but still couldnt get answer.. I wrote ammonium sulphate
The bio part was difficult for me as well
-
my curbe only touch 2 points!
aiya neh mind, got smooth curve can liaoz! -
i just remembered, i forgot to label my graph. LOL.

graph of x/cm aganist angle of incidence/degreeOriginally posted by LordIcarus:i just remembered, i forgot to label my graph. LOL.
x/cm(y-axis)
i/degree(x-axis) -
Been a while since I done this kind of experiment
-
Izzit use pins and view through a glass block??
Coz pure phy has that as well
Got curve as well too wtf man
2 way to improve exp...uh..repeat whole exp and widen range? -
to be honest i think the bio part this year more on theory work lehs...~~

i wrote calcium sia..kns..and for physics..i only used 1 piece of paper to draw the ray..haiz..supposed to use 1 paper for 1 angle de..didnt read the qn properly..lots of ppl committed the same mistake as me too..zzzzz..

hoseh liao...u mean u nvr use the rest of the pieces to draw the other degrees ? -
oh asyte. me too. i was rushing for time! oh man..deduct 1 mark right??Originally posted by LordIcarus:i just remembered, i forgot to label my graph. LOL.
