count the number of sqquares between the curves....

how did you get the ans man ? boxes are way more than 6.4

how did you get the ans man ? boxes are way more than 6.4

1box = 1 mj
you must be counting half boxes as one.

exactly so the scale is idk ??

u count any way hw is it 6.4?? this is scary hope dsnt cum 2moro....

How do you get the answer for R resistance November 2012 2(b)(ii) please help, isn't it getting a choosing a point on the line and then getting the R value?

what is the difference between superposition and superimposition ?

Calculate the gradient, which will give you I/V
whereas R = V/I = (I/V) ^-1 = Inverse of gradient.

see carefully....some the squares between the graph are half, make two of them as one...after some of these..you have to make approximations...

and yeah this is scary...and if something like this comes...for just 3 marks..i would rather prefer doing it in the end...after checking all my answers..

The nature of an alpha particle is 2p+2n, what does this mean?!

dun laugh plz boards hain n mjhe tension hai n ur laughing??

I have hardly studied physics throughout the year....god allah jesus knows how tensed i am....but the trick is to stay happy...and get on the preparations hard..

u say phy I dint study any subj thruout the year n nw no way cn I b happy
hw ur exam 2dy?? which variant did u give??

It's wrong, I did the same initially and mark scheme is different

..


I gave chem. p-22. leave that is gone..
tell me if you have doubts in phy. so even i can learn in solving them..

what? where is that given...?

 

[gary221]

what is the difference between superposition and superimposition ?

superposition is when 2 or more waves meet at a point, so the resultant displacement is the vector sum of the displacements of the individual waves.
nvr heard of superimposition.
whr did u rd tht??

well seriously what is superimposition?the 1 which is super impose

 

[gary221]

well seriously what is superimposition?the 1 which is super impose

is tht a physics - related term, or just generalized??

4 nucelon number
2 proton number +2 nuceleon number=4 nucelon number
