    pendulum help !

    When justifying experiments you should refer to accuracy, validity, reliability. For example, for small angles of swing the pendulum period formula is a suitable approximation and the technique is valid to deduce period. And as you have mentioned it is easy to increase reliability of results by...

    Transistors...switches and/or amplifiers?

    The more you understand the better your responses will be. The key is then to keep it succinct. The amplification part is that the current in 'internal' emitter-collector circuit is in proportion to the current in external emitter-base circuit. The proportion constant is huge so you get huge...

    question about generators

    No it says 'in contrast to THAT, AC generators...'. So it's saying AC generators are better for environment in terms of greenhouse gas emissions if say hydro instead of fossil fuels are used to power them.

    GPE

    The Ep of particle m1 with respect to m2 is generally -Gm1m2/r+constant where r is distance between particles. The constant is arbitrary so the simplest value we can let it be is 0. And that occurs if Ep=0 for r=infinity. For multiple particles same thing works from voltage superposition.

    Trigonometry help required

    There are two simple identities usually taught at higher 3u/4u from which you can simplify further: 1. cos(u)+cos(v)=2cos[(u+v)/2]cos[(u-v)/2] 2. cos(u)-cos(v)=-2sin[(u+v)/2]sin[(u-v)/2] Let v=pi/2-u. Then we get: 1. cos(u)+sin(u)=2cos[pi/4]cos[(-pi/2+2u)/2] 2...

    Do you think climate change is real, and man made?

    If you want to deny any aspect of AGW or put your own scale on it you should first refer to the papers published in climatology journals and the related experiments. This is a scientific matter like any other- either trust the authorities IPCC and consensus or do your own research backed by...
