June 2003 paper 01, q 20 .... ans is A but please some one xplain me
can u explain when we use v/2l and when do we use v/4l ? and plz in details cz am totally confused in thisi remember doing question with my teacher and he said there is something missing in the information given so we weren't able to do it
Q25
use equation f=v/4l for closed tube and f=v/2l for open tube where v is a constant speed of air in this case
so f ' =v/2l
and f=v/4l
divide f ' by f to get 2 which is D
q.13 it cant b D as forces hav to b equal and in opposite direction, they are prependicular here
can u explain when we use v/2l and when do we use v/4l ? and plz in details cz am totally confused in this
we r nt goin 2 re-arrange the forcesbut if you re-arrange the forces in D you get a couple but for A it is being pulled downards
why did u use both da formulas in da question??well according to my physics book f=v/4l is used in closed end tubes
and f=v/2l in open end tubes
3000 rev in 1 minuteOct/Nov 2010 paper 11. Question 5.
It's a question about the CRO. Anyone who's done it, can you please explain how to solve it?
THANK YOUUUUUUUUU shame i only got this now it looks like it could have helped a lot!that is a potentiometer anways see these notes
because one tube was closed while the other is open and they said find ratiowhy did u use both da formulas in da question??
oki thnx =)because one tube was closed while the other is open and they said find ratio
3000 rev in 1 minute
so in 1 sec = (3000/60) =50
50 rev per second now this is the frequency
so period is 1/50 which is 0.02
so 1 wavelength takes 0.02s so to get a good shape 0.01 should be used to show have the wave as well so answer is B
but how can A be a couple???we r nt goin 2 re-arrange the forces

Thanks. I understood up until the part where you find the period, but beyond that, I don't see how you got 0.01, and thus 10mscm^-1. Could you please elaborate on the last point?
Sorry for being a bother.
we r nt goin 2 re-arrange the forces
