Calculate the nuclear magnetic resonance frequency of a single hydrogen atom consisting of a proton and an electron with a magnetic field of 10 Tesla. The gyromagnetic ratio of the proton is 2.675 x 10^8 rad s^-1 T^-1 and the electron is -1.761 x 10^11 rad s^-1 T^-1. Given that the hydrogen atom has a natural frequency of 1.42 x 10^8 Hz, determine the energy required to make the spin-flip transition of the proton to the opposite direction.
