Those are only published when there is some change in the syllabus...

Question?
Answer is attached too... Just wanted to ask do we write the uncertainty in such part of the answers... Like if I get .22 mm diameter... Can I write the answer as .22 +- .01? Is that "answer + uncertainty" or "range" given in the marking scheme as .19+- .02 mm? And also what does that SV mean in the marking scheme?

"You need to write the uncertainty every time you read a value off some scale etc. About the '.22 +- .01' part, that's 'answer + the uncertainty'. And the smallest possible reading that you can read on a micrometer screw gauge is .01mm so I think you can write the uncertainty as .01mm. I wonder why they've mentioned '.02mm' as the uncertainty Lastly, that 'SV' might stand for similar value or something like that but I am not really sure about it.

formula for emf is = WQ or W/Q ????

notes say emf = WQ .......

 

[unique840]

formula for emf is = WQ or W/Q ????

notes say emf = WQ .......

is emf voltage? if it is voltage, emf is w/q

 

[Silent Hunter]

if not ?

 

[unique840]

thn what is emf???

notes say emf = WQ .......

As-salam-o-alaikum!!

It is W/Q

 

[Jasmine01]

Assalamolaikum, can you tell me how to solve Qno. 13 and 14 of paper 1 of June 2005? I also need help with Q no. 15 of paper 1 of May/june 2006, Qno. 7, 10 and 13 of paper 1 of May/June 2007. Can you answer as soon as possible? My paper is due in two days. Thanks

 

[Jasmine01]

I also need help regarding graphs of kinematics in AS level. Can you post all of those related to the syllabus?

 

[Silent Hunter]

As-salam-o-alaikum!!

It is W/Q

waalikumslam .......... so those in xtremepapers notes should be changed ?

 

[OakMoon!]

waalikumslam .......... so those in xtremepapers notes should be changed ?

Yeah!

 

[grumpy]

it can be .02 my sir said it ranges from .01 to .03
but its much better to write .01
