A hydrogen atom in a state having a binding energy (the energy required to remove an electron) of 0.544 eV makes a transition to a state with anexcitation energy (the difference between the energy of the state and that of the ground state) of 12.750 eV. What is the energy of the photon emitted as a result of the transition? Use -13.60 eV as the binding energy of an electron in the ground state.
assume the current in the coaxial cable, see the figure , is not uniformly distributed, but instead the current density varies linearly with distance from the center: for the inner conductor and for the outer conductor. Each conductor still carrie..
