    Physics p2 and P5 gone now . Cmments?

    I did good for Paper 5 part two and "okeylah" for part 1...still had 15 minutes to check... Although the hall probe was a bit confusing, i mentioned using a detector which is connected to a meter ( i didn't mention what is that meter is)....I mentioned use of rheostat and many things...May be...

    HOW WAS PHY P33?????

    LOL...everything was fine....thx to PrincessZahra, Krypton Man(MAVtKnmj..... hard to spell), ashhadazam..and to all friends.... Exactly like predicted..... My intercept was a negative ( around -9.81) and gradient 1.19... First plot point for "2V"of power supply was funny too...far from my...

    Hiya guys.....all guesses with complete details about Paper 33 physics is in another thread....Refer to it./..... viewtopic.php?f=26&t=1145 Terminal velocity is affected by radius of the ball....

    Physics p33 errors

    Viscousity may be won't come...It's beyond our syllabus.....even, if the ask about viscosity...sure they will provide the formula..... And the formula doesn't have any pi......look at it again...I just included the formula just for you people to see to have a better background knowledge...

    Physics Practical/P33 Details and General Practical Tips

    And here i'm posting possible errors and method of improvements for the second experiment.... Error 1. small air bubbles are formed on the marble/spheres/(any balls being used) which hindered the motion of the ball 2. two sets of reading not enough to draw a valid conclusion 3. human error in...

    Physics p33 errors

    Hey guys...found this Cambdrige teaching AS Practical Physics in net... So, download it and have a look at those experiments....they're looking quite similar to those which came out for the previous papers.... Read about terminal velocity there..... http://www.scribd.com/doc/19920765/Camb ...

    Physics p33 errors

    Yeah...i'm thinking the same too...but both experiment are using the same methods, materials and apparatus. Just that we calculate viscosity using the formula below. But, it's fluid mechanics which is beyond our syllabus....But, sometimes CIE can go crazy... :D ... Viscosity = 2(ΔP)ga2...

    Physics p33 errors

    Dude...I saw the past year questions and the electricity related questions usually come first. So, i think that the diode question may be the long question as said by MAVtKnmj( pwewh....hard to spell).... And oil viscosity may be the second...anyway, we have to be ready for any situations which...

    Physics p33 errors

    I've googled for many sample experiments for this "oil viscocity". And visited a lot of pages to see how the experiment can be done, what are the possible errors, and improvement methods.. These are some of the good answers that I found. Oil Viscosity Error 1. small air bubbles are formed on...

    How to read the table values of t in t-test?

    @Ayesha... Thanks so much...But, I have another question....is Chi-Square related to t-test? Coz, in that question they are asking for chi-square right? But, in text book, they said t-test differs from chi-square...and they have different tables...

    How to read the table values of t in t-test?

    Hi guys, I'm not clear with t-test. I've tried reading the CIE text book "Statistics" part. Yet, I don't understand what is t-test for? What is null hypothesis? When the t-test should be used? How to read the table values of t in t-test? Thanks in advance.... :P

    need help in p3

    For the question 6( part 2 and 3 ), You may refer to P3 CIE text book page number 137. Example 10.4.2. It's exactly the same question with different values only.... :)

    *ABP* Examination tips and Best of luck!

    Re: Examination tips and Best of luck! Hey dude... Last time, when I did my AS, i was panicked too for many papers. That caused a terrible result.... But, when I was doing mock for A2..i tried to relax myself 15-30 minutes before the exam. And during the exam, tried to not "over concentrate"...
