How do you calculate the rise and fall of a temperature?  Also, Question 1, Q.3B, 4B how do you take the measurements?,   2009 OCT/NOV, i can't seem to understand what to do exactly. Also, what to do when you are asked to draw to rectangular blocks to measure something?

Thats all of my doubts of paper 6. Went through 2003 - 2009 and found that these are my problems.

I have the same problem with the rectangular blocks :(.

i thnk for ques <0625/06/O/N/05> 1-d u hve 2 do it thid way (lok at de pic)
measure de distance "d" and "l" using a rule n set square and den using tan theta find the angle
hope m correct
 :) ;) :P

jus draw a straight line in whinch the number of points on top of line is equal 2 number of points under the line (line of best fit) ;) :)

How do you calculate the rise and fall of a temperature?  

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  ..!!  :) :)

Also, Question 1, Q.3B, 4B how do you take the measurements?,   2009 OCT/NOV, i can't seem to understand what to do exactly. Also, what to do when you are asked to draw to rectangular blocks to measure something?

Thats all of my doubts of paper 6. Went through 2003 - 2009 and found that these are my problems.

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 .. :)

dont worry u r right .. but the ques says "suggest another method of investigating as reliably as possible the extent by which the rule is pulled down by the masses."

u dont need to worry about the angles .. :)

Hey, I have a problem with the ''light'' rays, topic, like when they give you a paper and set of question, like '' draw the normal line on the grid above '' I really have no clue how this works, I know it's so complicated to actually explain it why you're typing, so do any of you guys know a website or something for that kind off stuff? like drawing normal lines etc... with pictures and explainations, any link would be useful, thanks.
By the way, this question is mainly in holly Physics paper 6.
