Suppose the difference in rest energy of the neutron and proton were qn = (mn−mp)c 2 = 0.129 mev instead of qn = 1.29 mev with all other parameters unchanged (including the freezeout temperature for neutrinos at the time of big bang nucleosynthesis). estimate the – 2 – maximum possible mass fraction in he. you may assume all helium nuclei have two neutrons and two protons.'

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
