    physics paper 3, harder than hard

    Not now, after 24 hours, but man, question 2 wasn't hard as compared to others.

    physics paper 3, harder than hard

    The main source of problem is the time. I bet most of the students would have got an amazing mark if the paper was for 2:30 hours. If someday these British guys be in my hand, I will make the most twisted questions ever.

    I know dear, do u know about rules?

    physics paper 3, harder than hard

    Just take this advice from me, don't judge quickly, think and write, but also don't run out of time (its somehow impossible for some students).

    physics paper 3, harder than hard

    I couldn't believe it! SUCH SIMPLE QUESTIONS! I did them mistakenly, and by saying that I mean before the exam I had done extremely hard questions, but this paper was the worst paper I have ever done in this IGCSE.

    You're welcome. I'm leaving for the paper 32 physics, I hope I will not run out of time. All the best.

    Because the questions is like that :) It is actually for the other part (where you have to add the atmospheric pressure to something else). Depth h decreases less h = less pressure.

    Take a piece of paper, and a source which emits alpha particles, plus a radiation detector which would measure the amount of radiation in the area. How to do it: First measure the radiation in air when the source is not present. Then take the source towards the paper (alpha particles will get...

    In a specific pressure, there is a specific volume. So Pressure1 * Volume 1 = Pressure 2 * Volume 2

    GUYS HELP 4 PHYSICS PAPER 3

    Anyways one of them is rarer than the other :D Glass is more denser than water. So Denser to Rarer ... Sin r / Sin i.

    Physics, Chemistry and Biology: Post your doubts here!

    They might want to know the deviation of alpha, beta and gamma particles. So each single particle could be passed through a magnet (between N and S poles), and using the left hand rule the direction of force could be determined...

    The incident angle is almost parallel, which means it is almost 90 degrees, so 88-90 could be a good approximated value. And for the critical angle, is 43, since the angle equal to the critical angle goes out parallel to the line AE.

    GUYS HELP 4 PHYSICS PAPER 3

    Who cares? Just convert it! In Rarer to Denser = Sin i / Sin r (Air to Glass) In Denser to Rarer = Sin r / Sin i (Glass to Air)

    GUYS HELP 4 PHYSICS PAPER 3

    Its a bit complicated, its just for confusing candidates (CIE is so selfish.. :p)

    Yes, I have solved it.

    IGCSE PHYSICS

    If there is no curve (obviously there is), and you're just considering a single paper, the grades would be: A+ 100%, A 87-89%, B+ 77-79%, C 67-69% In IGCSE its different but, common sense says this..

    The heater: Generates heat. Cathode: It is heated by a low voltage current to emit electrons by thermionic emission. Higher current flowing through the filament will produce more thermionic electrons resulting in a brighter spot on the fluorescent screen. Accelerating anode: This accelerates the...
