6c)acceleration of alpha/acceleration of betaHey.Can you tell me how to solve the last part of the last question of O/N2011's 23 paper :/
ur welcumThank youu
yesWe are only supposed to use 'unified mass constant','elementary charge' and rest masses of electrons ,protons and neutrons from the data sheet for radioactivity questions,right??
Okay thanks
just move it 0.25lambda to the right that is wat i think
http://www.xtremepapers.com/communi...st-your-doubts-here.9860/page-105#post-292759That's what I thought too, but the mark scheme says: "horizontal line through central section of wave"; what does that mean?
The distance between adjacent nodes and adjacent antinodes is 0.5Lambda, right?
This is the general confusion here..no it is proportional to amplitude squared
alwayz give your answer in SIhttp://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w10_qp_35.pdf
1ai) In this part the diameter's units have to be in mm or m?
ii) HAs to be in mm2 or m2
b(iii) x should be in m or cm
c) In the table x can be given in cm or it has to be given in m?
Please help anybody
ok but in the marking scheme: http://www.xtremepapers.com/papers/...nd AS Level/Physics (9702)/9702_w10_ms_35.pdfalwayz give your answer in SI
in practicals u can use any units u lyk as long as u get the end answer in the right unitsok but in the marking scheme: http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w10_ms_35.pdf
part 1ai) is given in mm ??
