    OLevel Physics Lens Question, please answer quickly!! :(

    Offcourse I.... dont : P , but it doesn't mention how we can SET UP the experiment....I mean how are we gonna acquire a beam of charged particles? I figured out the static electricity wala part myself. http://maxpapers.com/wp-content/uploads/2012/11/5054_w11_qp_21.pdf Q7(a) here. If u know...

    Responsiveness is how quickly the thermometer reacts to the temperature change. In simple words, how quickly the heat is transferred from the object to the thermometer is determined by the thermometer's responsiveness. The responsiveness of the thermometer depends on how THIN the BULB of the...

    This is part of Physics Syllabus -describe experiments to show electrostatic charging by friction - describe experiments to show the force on a beam of charged particles in a magnetic field how to prepare for thiiis?

    The two out of three results that are CLOSEST to each other are the best titration methods. That's what out teacher taught

    Also, do u know when the repulsive forces between two suspended rods (of like charges, offc) would be greatest; http://papers.xtremepapers.com/CIE/Cambridge International O Level/Physics (5054)/5054_s10_qp_41.pdf ATP Q4 ^ The marking scheme is, as as usual, vague about the answer. Or maybe I...

    OLevel Physics Lens Question, please answer quickly!! :(

    Off course, But isn't it a given that we're using a metre rule,100 cm, while H0 is 75.5 cm. We don't have to state that in the question That IS what you meant right?

    OLevel Physics Lens Question, please answer quickly!! :(

    i know u meant H zero, but my ruler being bigger than H zero?? You mean my EYE should be above H0? So I scored 26, not 25, yayy!! :).

    OLevel Physics Lens Question, please answer quickly!! :(

    But the answer to the formula wala question in the marking scheme - it's based on metres! I used cm in MY answer and my value was more, by a power of 10, than the answer in the marking scheme. :| I know it's perpendicular to the scale, but would it at the TOP or BOTTOM of the line? top, right...

    Question plis? Is it some universal law that we only use metre values in formulas http://papers.xtremepapers.com/CIE/Cambridge International O Level/Physics (5054)/5054_w10_qp_41.pdf Q1.c (iii) They've given us a formula to calculate something from values obtained from previous answers. But...

    OLevel Physics Lens Question, please answer quickly!! :(

    On the contrary, I find this a much shorter answer. And easier to demonstrate via a diagram. Plus, it MAKES SENSE TO ME :D

    OLevel Physics Lens Question, please answer quickly!! :(

    They're part of the syllabus, though. There's a question in ATP that requires us to ensure that the focal length of a lens is 15 cm (2009 ka paper) What I wrote; since an object at 2F (2 X focal length) forms an image at 2F, too we'll place an object at a distance 30 cm (15 X 2) from the...

    OLevel Physics Lens Question, please answer quickly!! :(

    I mean, are we relying on what WE see through the glass block, cx we don't have a ray box? WAAAAAAAT? Edit: I tried to understand this. What I've been able to wrap my head around (AND DON'T JUST SAY ''YA YA YOU'RE RIGHT'' WITHOUT READING THIS) is that the optical pins are being used as markers...
