Atomic physics is the field of physics that studies atoms as an isolated system of electrons and an atomic nucleus. It is primarily concerned with the arrangement of electrons around the nucleus and the processes by which these arrangements change. The theory of quantum mechanics, a set of mathematical rules that describe the behaviour of matter and its interactions, provides a good model for the description of atomic structure and properties.

In physics, nuclear physics is the field of physics that studies the constituents and interactions of atomic nuclei. The most commonly known applications of nuclear physics are nuclear power generation and nuclear weapons technology, but the research has provided application in many fields, including those in nuclear medicine and magnetic resonance imaging, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology.

so it was a passage. But there is this reaction in which, in electron and a positron collide with each other, they then they animates and invent. So photos savior to put us and CeCe my questions questions is speed ain't asked us what is energy of each other's photos. So when we have an electoral deposit chul, it's a condition energy. We have ISS two times in E. C Square. So this is the energy due to the mass ofthe electoral enters posture. See, question was a passage told us that the speed is pretty much yes across the passage. For us, that's a natural functions. Obelix slowly certainly is. We do not need to consider it circulated energy and so in. But it is a choice, Lay it says half empty school were B is the speed of posture. So we are neglecting that here and because if we look at it with mechanic energies and evey square and will be a small and obvious more already, this is gonna be so much smaller than says, because C is huge. So is this Louis's of energy? But we also have two daughters, so, to Emily C. Square will be distributed evenly over city photos, so energy for each photo will be any C square in which is choice d.
