    "Provided our consumption does not exceed its natural level of production, the burning of biomass should generate no more heat and create no more carbon dioxide than would have been formed in any case by natural processes." What do you think about this in terms of long-term wood burning to heat homes in rural areas? Specifically under what circumstances would you consider this acceptable or unacceptable?

    Under usual conditions a particular drug is known to have a pH that is normally distributed with mean 9 and variance 0.25. If pH of drug is either lower or upper 15% distribution, it is not acceptable.In a random sample of 36 different drugs, approximate the probability that more than 30 of them have acceptable pH level.

    18. Every electron in the universe is the same as any other electron. It is a symmetry of physics, that if you interchange any pair of electrons, the Schrödinger equation is invariant. Consider one pair of electrons which we call electron-1 and electron-2. Define the interchange operator P12 to simple interchange the two electrons. H4142 = EU142 HP120142 = EP120102 a) Use the above equations to show that the P12 operator commutes with the Hamiltonian. b) Use that fact that...

    What is the minimum uncertainty in position, in nm, of an electron whose velocity is known to be between 2.94×105 m/s and 3.88×105 m/s ? You may have used the reduced Planck constant in the uncertainty principle. Note that in statements of the uncertainty principle the right side could have different meanings (just h or it could contain various factors of PI), but we have h/2 *******THE ANSWER IS NOT .615, .616, .617******** Please Help
