    that might be correct man. CRO has come in papers many times and i remember two radioactivity experiments also. to show that the radioactivity is a random process. not sure about reed switch.

    use HB pencil. i use HB with EXTRA DARK. it is little more expensive but even with sharpest tip it is visible. although it must be sharp as there is a mark for it.

    PHYSICS ATP TIPS, EXPERIMENTS AND FEQs

    i dont remember those papers which i did probably first variants or igcse atp. we found combined resistance of 3 resistors and the sum of the resistors. theoratically they must be same, but they are not. we have to say whether theory is supported by evidence or not. actually it is supprted as...

    HOW TO FIND FOCAL LENGTH OF COVEX LENS VERY ACCURATE in figure 1, a mirror, lens and object are on same axid prependicular to surface. the light from the object goes to lens get parallel come back and create image beside object. when the image is clear that length is accurate focal length. To...

    PHYSICS ATP TIPS, EXPERIMENTS AND FEQs

    I will try to put everything i have learned from doing past papers into nutshell. Frequently examined question: theory suggests that resistance should be 10 ohm but in experiment value is 12. Given that experiment had no errors, does this experiment support theory?Experiment supports theory...

    if we take the reading from distance we get confused about the exact location. we have to take shortest distance from that point to the rule and that point on scale is the actual reading which is not clear due to it being away from object. set square is 90deg triangle therefore it we but its...

    CIE says that we are banned to talk about it in keytime. according to them we should be kept under supervision of centres as other countries are having same exams and we can pass them on. but they release us early. the key time will end at 1200 PST but XPC is too coward to allow even after 2 hours.
