    Physics: Post your doubts here!

    Dude, how did you calc the resistance 2000 for component C, the graph doesnt even tell that. We only have to figure out that its prob more than that of Resistance R, cause from the graph we know C arleady has a resistance of 1500 at 6 V, so obv at 7 V its going to be higher, well not exactly...

    LOL, I didnt ask for a solution, I was only telling daredevil that this was an example of the question she wanted. :P Anyways, Good job, bro. :P :ROFLMAO:

    so how are you going to do this one? http://papers.xtremepapers.com/CIE/Cambridge%20International%20A%20and%20AS%20Level/Physics%20(9702)/9702_w10_qp_22.pdf q4 b. I dont get the method actually. :D

    have you tried the method? like does it give the value anywhere close to the answer? cause I dont think it does :P

    Thats exactly what I told you NOT to do. :D I checked the ms, they just use the UNIFIED ATOMIC MASS CONSTANT for both. so if you have like 12 nucleons, regardless of whatever the number of protons is, you multiply 12 by 1.66*10^-27

    Yeah I have the same problem, but what I always do is consider the curve as a straight line which doesnt always give the exact answer. :P

    Dont forget these (they're the ones that I came across while solving the past papers and are not mentioned in the book :P) : mass of a nucleus: 1*10^-25 kg radius of a nucleus: From 1*10^-15 - (1*10^-14) m radius of a proton = radius of a neutron = 1*10^-15 m size of an atom: 1*10^-10 m size of...

    Oh, dude I just did it yest. :DD P(a,0) Q(0,b) now the distance PQ= [a^2 + b^2]^1/2 = 45^1/2 a^2+b^2=45. substituting (a,0), y=-1/2 (x + a) 2y=a-x ---> (i) Now substituting (b,0), y-b=-1/2(x-o) 2y= 2b-x ---> (ii) a-x=2b-x a=2b Now plug in the value of a in the distance equation to get the values.

    I solved it just yesterday. Now write down the numbers for the first model: they are going to be 1000,2000,3000,... 5 percent donated everyday, 50,100,150. first term is 50, common difference is 50. solve for the sum of 40 terms. you get 41000 For the second model, do the same...
