  1. Would I be right in assuming you are referring to disulphide bonds between amino acid residues?
  2. I'm not really sure what ideas you are expecting to see, but Wikipedia does have an article on water. Hope that helps
  3. If you apply a voltage that is less than around 2.60 V then theoretically you shouldn't get H2 or O2 being produced at the electrodes. But I'm not sure about what will happen with the movement of the ions.
  4. Do you realise that 20 to 30m/s is 72 to 108km/h? I would think that is a little fast to do by hand. Well, you can use EMF(peak) = NBAw to work out the peak voltage produced. Where, N = number of turn of wire (coils) B = magnetic field strength in Tesla A = total internal area of the coils w (which is meant to be a small omega) = angular momentum [ = 2(pi)*frequency] But as you said you don't know the field strength...so, you could use F = BIl to work out an approximate B (field strength), from known force, current and length of wire. This might explain what to do.
  5. The factors that determine if a fuel cell is more efficient, or better for the environment, compared to something else are based upon things like what kind of fuel cell it is, what reactants are used to run it, and where those reactants have come from. You probably should have a read about fuel cells, that will make the argument between you and your friend more understandable.
  6. "change in kinetic energy" doesn't equal 1/2 (m)(v)^2 "kinetic energy" = 1/2 (m)(v)^2 Newton's equation (sum of)F = ma And the fact that "power" means "energy per unit of time" may also be useful
  7. Not all instances of genetic engineering, that I've read about, were aimed at disease protection. Some modifications were designed for plants/crops to be able to survive frost or grow in very cold conditions, while the original plant would have failed in such circumstances. And then there's the possibly over-ambitious ideas of some geneticists to modify vegetables to taste like chocolate, etc.
  8. Well, lets assume a mirror can reflect infrared light. A mirrow reflects light that is shined upon it, so what goes in will be pretty much the same as what comes back out. If you can't see the infrared light going in, will you be able to see the infrared light coming out?
  9. It really depends on what kind of stem cell research you are talking about. There will be different issues associated with embryonic stem cells compared to adult stem cells, etc.
  10. You have to keep in mind that the melting temperature of a substance is dependent on factors such as pressure. At the core of the Earth, I can only imagine that there is a fairly significant amount of pressure against the very hot ball of metal. As for its properties - I have no idea. I'm not well versed in the theory of what ever topic the centre of the Earth would fall under. _____________________________________________________________________________________________ Ahhh, beaten to the punch
  11. I think that would depend on the metabolisms the various bacteria and mysterious entities are using.
  12. Are you intending to theorise about what the imaginary mixture will look/smell/taste like after the above mentioned process? Or whether certain parts of your process are possible (like the "phantom bacteria" idea or even the mysterious entity)?
  13. Just thought I point out that when you looked at the ratio in coloured light you were comparing wavelengths (450 nm and 675 nm) not frequencies like in sound. Anyway, I also agree with swansont. But, it was an interesting idea.
  14. If you have electrochemical cells and the concentrations of your reductant and oxidant are not standard (i.e. not 1M) then the Nernst equation should be what you want to look at. http://en.wikipedia.org/wiki/Nernst_equation
  15. I hope they haven't stopped using iodine in foods/salts, because that would mean a whole lot more people walking around with goitres!
