    24 hrs r up......full time analysis phyx P12

    Well the answer tothe dispalcement time graph was A for sure. The answer of the question of moving +vely charge from X to Y was B and that was quite easy. well i thinkk that the answer to question regarding min uncertainity was D i.e. 2, 4 and 5.

    24 hrs r up......full time analysis phyx P12

    The answer of the dispalcement time graph is A and that is almost 90% confirmed. I got the force 4.8N and i think its right because tension will be in both the strings.hey guyzz what about that question in which we have to estimate the frequency of visible spectrum???

    HOw DID THE PAPER GO???

    not only 4..There were almost 10 questions repeated and overall the paper was easy !!!

    Physics MCQ help.

    Q1 done(the one u asked at the top) the density of mixture = 4p/3. the volume of first= m/p the volume of second=m/2p. total volume =3m/2p total mass=2m density of mixture=2m/(3m/2p)=4p/3. hope it helps^^^..

    physics mcqs help required URGENTLY!

    even question 18 is not much difficult. If the height on the RHS is increased by h, it means that the liquid level on the LHS is also decreased by h. Thus the total pressure = increase in pressure at RHS+ increase in pressure at LHS =ρgh+ρgh =2ρgh. hope that u understood.

    Physics AS

    yea...and it wont be 0.2 J becoz the area of triangle is 0.1J and the area above the triangle is not equal to area of triangle, thus the total area becomes 0.11J.

    MECANICS!!!!

    hey guyzz.. what was the answer of that question in which we had to find the upward force.. whether it was 1360 or 340???

    How did mechanics go?

    The gt will be high as most of the candidates in my centre are getting full marks...
  15. Rockstar3143

    So how was Physics P33?

    Nearly everyone in my centre was getting a -ve y-intercept, but the gradient was in b/w 6 to 7....
  16. Rockstar3143

    Maths paper 42 grade threshold

    The gt will be 45 +, because this was the easiest paper of m1 ever........................ :)
  17. Rockstar3143

    Chemistry 9701/P22

    yeah guyzz.. the paper was easy but still it wont have a too high GT......... and Kc was 2.25 not 0.44.. :)

    the perfect titre......!!!!!

    all the people in our lab got more than 35 cm3 titre..only two or three students got less than 38 others got evn more than that and a few people also had even much greater than that i.e 40 +.....................

    Nucleophilic subsititution or addition?

    well.... its a real shortcut.. alkenes:- always electrophlic addition of things like Br2, HBr, etc. aldehydes:- always nucleophilic addition of HCN.. alkylhalides:-always nuclephilic substition of KCN (alc) or KCN(aq). benzene ring:- electrophilic substitution.
