Hi! I am offering 1-to-1 (and possibly small group) tuition in: -HSC and Year 11 Mathematics (Advanced, Extension 1 and 2) and Physics. Math and Science subjects for younger years. -Other high-school level Math and Physics e.g. A-levels, IB, Olympiads. -University level Math and Physics...

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...

Update: positions are still available. I am also offering tuition or preparation for university 'advanced' mathematics and physics.

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...

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.

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.

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...
