Aprimary cause of dephasing during nuclear precession comes from local variations in the magnetic field, ab. the mechanism can be characterized by the relationship connecting the actual spin-spin relaxation rate (1/t2) to the apparent spin-spin relaxation rate by 1/な-1/t2 + γδb here ? is the gyromagnetic ratio, which is related to the resonance condition by fo o first assume that the average frequency of precession in a sample is fo 15.24 mhz, due to an average magnetic field of b0-3.579 kg. you measure an apparent spin-spin relaxation time of = 768 μ s. the resulting range of magnetic fields is ab-g. hint: you may ignore t2 because it is much larger than t2

Which describe reflection? check all that apply. light bounces off a boundary.

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback
