    Maths P32 GT and paper discussion

    I actually found the paper in medium difficulty.... Alot of people in my center said it was tough with 1 or 2 exceptions saying easy :p .... Actually in reality it was tough so KEEP CALM AND PRAY FOR LOW GT :)

    CHEM P42 GT and paper discussion

    Chlorine is already a gas so no need of the atomisation energy :)

    CHEM P42 GT and paper discussion

    Indeed the paper was easy but i highly doubt the threshold to be high as 70+... the highest i have seen was 68.. maybe around 60-65

    Need help with my grades

    ummm... i'm not sure of it being easy but since you have done it before and doing it again i guess it would be. And yea you need to sit for all 3 papers for one subject

    Need help with my grades

    lol you did great dude. Don't resit that would be stupid continue with your A2 and work hard i'm sure you can get A* :)(y)

    Need help with my grades

    If you don't want to repeat it you don't have to. But you need to get atleast more than 85 or 90 to secure a B which is tough given that it's A2. So the best option is to repeat it with A2 that way you won't be loosing time.

    http://bangladesh.exams.britishcouncil.org/cie_result.php you just need your candidate number, your birth date and centre number. That's it good luck

    how was physics paper 12? (no discussions till 24 hours)

    There were two first orders one above zero order and one below... if you use the formula sin^-1 (wavelength/D) you would find the angle between the zero order and 1st order only.. But the question wanted the angle between the two first orders so you need to multiply by 2

    how was physics paper 12? (no discussions till 24 hours)

    The diffraction grating question's answer was 2sin^-1 (wavelength/D) ... and i got 5* 10^-11 for that alpha particle question... The power station question i got 1.5MJ don't know how but i did... well these are my answers

    how was physics paper 12? (no discussions till 24 hours)

    the question said it went up and moved left meaning a projectile motion that's why i gave C.

    how was physics paper 12? (no discussions till 24 hours)

    hello people :D i gave C for the ball that was thrown up and moved left. My logic was that the ball was thrown in a parabolic kind of motion to the left. There was no resistive force acting on it so yea the answer was an arrow pointing down and left

    it was 41 W and i don't remember the unit for C :p it's been so long i forgot. Good luck in paper 1 (y) :)

    Bro i asked my teacher he said you are supposed to use the area under the graph which is energy. that is what i'm trying to say here. Area under a force vs distance graph is energy we know the total energy of the trolley which is 1.3 J
  16. I don't care

    physics 22

    i didn't mention anything about w=fx the only way to correctly do the question is to take the area under the graph which is energy and the total energy possessed by the truck is 1.3 j 1.3=1/2 * 14* pq

    physics 22

    nope it wasn't constant, it was changing throughout the motion. you can only use the equations of motion when the acceleration is constant but in this case acceleration and force are not constant. so you need to use energy to calculate the distance.
  18. I don't care

    physics 22

    You can't find the acceleration like that the acceleration varies with the graph and so does the force. altough it's a straight line, the v/t graph would be a curve. the area under the line was energy force plotted against distance so yea. we had to use the k.e to find the distance.

    0.05 was i/4 th a wave since it's a stationary wave i drew a flat line :/ don't know if it's right

    I got 120 m in question number 2 what did you people get? i got 0.19 or 0.18 in pq distance
