can someone explain to me kirchoffs second law? even though i get it, im unable to solve the questions related to it.

For question 26: I is directtly propotional to the Amplitude squareplease explain me question number 24 and 26. http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s08_qp_1.pdf
thanks manFor question 26: I is directtly propotional to the Amplitude square
and the given propotionality is I is inversely propotional to the the distance X
Now forget this and understand what i'm saying: A Is directly propotional to B,and B is Inversely propotional to the C
so it will be equal to the A is Inversely propitional to the C
NO WHAT THE QUESTION SAYS
I is directtly propotional to the Amplitude square
the given propotionality is I is inversely propotional to the the distance X
SO THE THIRD PROPOTIONALITY WILL BE :
Amplitude^2 inversely proptional to dstance X^2
so a1^2 x1^2=a2^2 X^2
a1^2=8.0 micrometres
x1^2=r
x2^2=2r
a2^2=?
so putting the values we get a=4.0 micrometres
ok just see.isotopes are the atoms of the same element that has same proton number but different neutron number.so u can assume that p has a proton number of 60 and nucelon number of 90.do calculation and u will get bcan someone please explain mcq 40 of winter 2012 paper 11

but the final speed in graph A is not same as initial speed of both skatersSmith and Jones are skating on a friction less surface hence, there's no loss of energy before or after throwing the ball. The initial and final speed for both skaters should be the same. Only graph A shows smith and Jones returning to their original speeds after the exchange.
sorry the correct answer is CSmith and Jones are skating on a friction less surface hence, there's no loss of energy before or after throwing the ball. The initial and final speed for both skaters should be the same. Only graph A shows smith and Jones returning to their original speeds after the exchange.
but the final speed in graph A is not same as initial speed of both skaters
maybe the book is wrongIt is, the A is a speed time graph, the speed fluctuates between t1 and t2 and then comes back to the same horizontal axis so the speed is same.
fr no.26 by doing calculation we get the number of order 3.then they are asking the number of images can be formed.so 3 images will be formed on x and 3 on z and a straight image through yAsalam-o-Alaikum!

could anyone please help me here with questions: 12, 26, 35 and 39??
thanks!
