That Percentage is The uncertainity in R.. So its 1.9% of R value.http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w07_qp_2.pdf
Question 1 (b).. Found the percentage uncertainity of R as 1.9%.. percentage removed would give 0.019cm ... Then why is the answer 0.009cm?
% uncertainty = (uncertainty/reading) * 100http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w07_qp_2.pdf

wowowowow! Do we follow same for all uncertainty questions ?% uncertainty = (uncertainty/reading) * 100
1.9% = (uncertainty/0.4886) * 100
0.019 = uncertainty/0.4886
uncertainty = 0.019 * 0.4886
[ uncertainty ≈ ± 0.009 cm ]
Yup, im doing edexcel A level n i do it like dat ova der toowowowowow! Do we follow same for all uncertainty questions ?
The time period of the stationary wave is 20ms. After 5 ms, it would be a straight horizontal line, drawn on the dotted line. Take a look at this animation and you will understand the logichttp://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s13_qp_22.pdf.....
Q.no.5 b(iii)...A little bit of a help in graph part...anyone?....
Can you elaborate a bit more.....I mean, won't the wave travel a further more after 5 sec...and for the wave given isn't the time period 30m/s....a bit confused here....The time period of the stationary wave is 20ms. After 5 ms, it would be a straight horizontal line, drawn on the dotted line. Take a look at this animation and you will understand the logic

Which is 0.0489.
Now You will have to :
1.9/100 * 0.048 = 9*10^-3 = 0.009 cm :3
Thankyou guys :') I figured it out too% uncertainty = (uncertainty/reading) * 100
1.9% = (uncertainty/0.4886) * 100
0.019 = uncertainty/0.4886
uncertainty = 0.019 * 0.4886
[ uncertainty ≈ ± 0.009 cm ]
You'r Welcome!Thankyou guys :') I figured it out too
But thanks alot
If i am not wrong you have posted in the wrong section/thread. This is for AS And A Level.can someone please explain the bird question and the turbine question. (question 2 and question 3) please reply ASAP
