Those are only published when there is some change in the syllabus...could someone send me physics specimen papers october /november 2011
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?
ffaadyy said:"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.
can u send me maths revision notes A LEVEL and some working exercises please
is emf voltage? if it is voltage, emf is w/qformula for emf is = WQ or W/Q ????
notes say emf = WQ .......
As-salam-o-alaikum!!formula for emf is = WQ or W/Q ????
notes say emf = WQ .......
As-salam-o-alaikum!!
It is W/Q
Yeah!waalikumslam .......... so those in xtremepapers notes should be changed ?
