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 in this question we have a sample of charcoal that is 55 grams and it decates at a rate of 0.8 to the back so foom, for example, 3.4. We know that the activity of carbon in the atmosphere the present day is 0.255 back program. So because of toffies 57 sidier. So if this is a rate, what we'll say that we will expect that 55 gram we'll have to it in present day? If this is a great per gram and we have 55 gram, we will expect a rate of 14, but so this is the same sample of charcoal present day. It will have a decay radio 14, but right now we only have 0.877 so 0.877 over 14. It'S around 116 point, so it's decaying at 1 d, 16 of the rate that it's supposed to be, and we all really see that the decay rate- actually it decreases exponentially. So after each half life, the decay rate has happened, and now, if this decay rate is 116, that is, it has gone through 4 half life. So the time it has experienced is 4 times half life, which is 4 times 5730 years, which is 2.29 times 10. To the force years, so the canticle is that to ride it has case 4 times some half rate as a half life.
