Got a physics paper 6 question.
http://www.xtremepapers.com/papers/CIE/Cambridge IGCSE/Physics (0625)/0625_s06_qp_6.pdf

Q1)d)

it is estimation so about 7.2 it is only estimation if u look thoroughly through this thread in the previous pages someone asked the same question and we said it was estimation hope u got it

Q1)d)

Assalam-o-alaikum wr wb...
In estimation..you have to round it off to 1 significant figure (as written in the examiner report of the same paper)

in this case...
Volume = lbh
= 5.8cm* 6.0cm * 0.2cm = 6.96cm3 which you can round off to 7

hope you got it

Oh wow, didn't realize it was a card with the same LENGTH and WIDTH of the previous ones..
My bad

How to draw the graph for such values like 0.031 0.0418 0.05 0.0584 0.0662 against 40 50 60 70 80 ?

start with 0.03 at the origin and then each block is 0.01...

hi everyone this is for paper 6 physics so again if u have any questions just ask and paper 6 will be discussed here!!!after that chemistry paper 2 will be discussed here too instead of waste of threads!

Hey I wanted to ask about the best fit line graphs and straight line graphs, in some Questions the points are scattered and it says to make the best fit line so do we have to make a curve or straight line joining 3 points and leaving 2 behind ?

Basically you place the test-tube in between the 2 blocks of wood since a test-tube has curved ends you won't be able to measure it accuratley with a ruler.
Now that you have 2 straight ends, it's much easier to measure the test-tube's length

 

[Mustafa omar]

Ok so when we measure it with the ruler
We measure the edge or not ?

Yeah you measure the INSIDE edges of the blocks of wood, the ones that are touching the test-tubes.

 

[Mustafa omar]

Ok thx

 

[shiznini]

How can we check if a meter rule is vertical and/or horizontal?

 

[white rose]

for horizontal -measure 2 equal heights from da bench
for vertical -use a protractor/ set squares/ plumbline/spirit level

what does spirit level mean?? can u explain it

 

[ZainH]

what does spirit level mean?? can u explain it

Its a instrument used to make sure a surface is horizontal/vertical.
A spirit level is this device:

AND

CAN SOMEONE PLEASE ANSWER THIS QUESTION:

The three lamps are now connected in parallel with one another. Draw a circuit
diagram of the three lamps connected to the power supply. Include in your circuit
diagram
(i) an ammeter to record the total current through the lamps,
(ii) a variable resistor to vary the brightness of all three lamps,
(iii) a voltmeter to record the potential difference across the lamps.

AND
Question No. 1 b)
