    Can anyone send a good summarized notes for Chem?

    Hey guys, Since Chemistry is on the horizon, and there is little time to revise through our long notes and texts, can anyone here post a good summarized notes of all chapters?

    I guess I have seen enough of Physics for today lol. Goodbye Physics paper 3.

    Yes, you had to convert.

    Poll:Physics p31

    What I can say guys, for questions that required some thinking, the answers can be different for many people. CIE accepts a wide variety of these answers.

    I don't think so because all they wanted was to name the components to be placed in A and B

    A Almost similar.

    *** was that(physics paper 3)

    Um.. how can there be a constant speed 2 times. For a constant speed the line has to only be straight nothing else. This is not actually a speed-time graph.

    GUYS HELP 4 PHYSICS PAPER 3

    Time delay circuits are circuits having a lamp which switches on after some time. That is because a capacitor is used which is charging up; i.e storing electrical energy. After sometime the energy is high enough for a lamp to switch after some particular time.

    That's all actually,and you have to know it used for time delay circuits.

    It is a device that is used for storing electrical energy. It works by charging up, mainly a voltage from a battery.

    Don't confuse yourself in that thing. There is an equation for power loss and such stuff. There is no need to know the details.

    I guess peak to peak height is amplitude. It is controlled by the y-plates.

    And for Period. Period means the time taken for 1 complete cycle of a wave. Time base is actually controlled by the X-plate. If the time base is 10 ms/cm. It means that the spot takes 10 ms to move 1 cm. It basically means 1 cm= 10 ms. Now if the peak to peak distance is 4 cm. Then the time...

    See: Peak voltage. When the gain control is 5 V/cm it means that each cm represents 5 Volts. Now if the amplitude of the wave is 2 cm. The peak and highest voltage should be 10 V. 5 x 2=10
