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

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
