Anegligible amount of this energy goes to the resulting 5726fe atom as kinetic energy. about 90 percent of the time, after the electron-capture process, the 5726fe nucleus emits two successive gamma-ray photons of energies 0.126 mev and 1.40×10−2 mev in decaying to its ground state. the electron-capture process itself emits a massless neutrino, which also carries off kinetic energy. what is the energy of the neutrino emitted in this case?

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
