Select the factors that lead to the production of a high-energy bremsstrahlung (brems) x-ray when a filament (projectile) electron interacts with an anode tungsten atom (select the four that apply) A The filament electron passes far away from the nucleus of a tungsten atom. B The filament electron travels close to the nucleus of a tungsten atom. C The nuclear electrostatic field creates a strong force of attraction on the passing filament electron. D The nuclear electrostatic field creates a weak force of attraction on the passing filament electron. E The filament electron arrives at the anode with high kinetic energy. F The filament electron arrives at the anode with low kinetic energy. G The atomic number of the tungsten atom is high. H The atomic number of the tungsten atom is low.
