Don't bother with papers earlier than 2000.
I can swear the syllabus changed, because Qs in 1995 are like lengthy, weird and never seen before.  :-\

S0 = 37.4 cm
S1 = 40.5 cm
S2 = 39.8 cm

b) i) e1 = (S1 – S0).

    ii) e2 = (S2 – S0).

Simply find the difference... :P

Now, in p6  November 2008 Q 1 part d
why does the extension becomes greater, even though the mass and the material is the same , its just longer .?
isnt it the same mass .. means same weight of the load == same extension of spring  ... :S :S

It says the the load is too long to be submerged in the beaker..It means that the extension is longer than before...As for the previous load...it could submerge in the water...And it said its the same mass and same material...But the volume could be different i suppose?
so D-i is greater


Hope u got it ?

i had a problem with my conncetion and thought it didnt post ..  
 
u guys i figured it out .. its actually simple, they measured the externsion from below the load , not the end of the spring, Therefore the longer it is, the larger the length even though it has  the same mass

Fiducial point, as in a point for recognition or a point you can familiarize with.
For example, when a pendulum bob is swinging, you pick a point, e.g when the pendulum is the furthermost left, and you begin counting from that point. When it returns to that point again, you count one complete cycle has been done.

Meaning, where to begin counting from.

Rise and fall in temperature ?? look at ques 5 in the attached paper .. b) i) Initial water temperature is 22o C .. when the cylinder is added Final temp = 36 oC .. so 36 - 22 = 14oC
 .. ii) Initial temp of cylinder is 100oC .. when place in water (which is 36oC)
= 100 - 36 = 64oC .. jus read the ques properly  ..!!  :) :)

u obvi. measure by scale !!.. if ur wondering the ms ans differ because the printout which u may hav wld not be according to the pdf so the sizes may differ .. :)


Thanks! +rep, Well do you know how to solve the other doubs i have which are all from oct/november 2009! Also, how do you measure the illuminated object thingy when it tells you the apparatus is drawn 1/fifth of actual size....what do they mean by it? again thank you and to anyone who answer my doubts.
