I'm (:
hahahhh!
cause i managed to change my mistakes in time!!
today's SPA's on electricty and we were supposed to find out how the length of the wire affects the current passing through..
this is the given equation: L= p(1/I)+ q
so we had to plot the graph of L against (1/I)..
and my units were wrong!!
L's supposed to be in metres, not cm!
and how did i realise it?
mr ng was walking around looking at our scripts,
den he looked at jiayi's (jiayi's beside me so i can see her) script, den mine..
but he looked at mine for very long! (maybe it's only i feel this way..)
anyways~
den i kept checking my paper cause my value of p,
which is gradient of the graph, is 33+!
den finally the 0.1m on the qn paper stood out to me..
den i realise my mistake..
i very slow hor..
though i hesitated whether to change all my ans as it affect like everything:
-the graph axis
-the graph title
-the table title
-CALCULATIONS!!
but fortunately i managed to change all these in time in <5mins! phew!
tmr's chem SPA 2!
hope i can do it too!
everybody JIAYOU JIAYOU JIAYOU!! (:
