(1) Physics P6 May/June 2007

Q3 Part (b) and (c)

                    
R is proportional to 1/d2
When we times the diamter by 2 we divide the resistance by 22

Draw 2 lamps and a voltmeter all in paralell and an ammeter in series.

(2) Physics P6 October/November 2006
Q1 Part (c)
Q3 Part (b)
V=7.64 taking l as 4.
for the actual volume of the rods you have two guess what fraction is air. I guessed 10% then d=m/V=6.3/7.64=0.82g/cm3

Put the pins as far from each other as possible. Line your eye up with the base, since the pins may lean over.


I have to go and teach some maths now. Back in a few hours to answer the other question.

Q80BOY:
Thanks astar !!  ;D

Q80BOY:
I added some more questions

(4) Physics P6 October/November 2005

Q2 Part (a) <-- i put the resistors AB and BC in sereis, and resistor CD in parallel, i put the voltmeter in parallel (under CD) am i right ?? Plz help !!  :'(

(5) Physics P6 May/June 2005

Q2 Part (a)
Difficult to do with a sketchb but draw the same diagram with a box on each connecting wire and another between A and D with a box.

(5) Physics P6 May/June 2005

Q3 Part (e)
r=0.95/0.375 FOR aB length 0.5m. If you triple the length to 1.5m you triple the resistance to 3(0.95/0.375)

Q80BOY:
Thanks astar, can u plz help me with the may/june 2006 (questions are at the top)
