Carbon-4 is an isotope of carbon thát is formed when radiation from the sun strikes ordinary carbon dioxide in the atmosphere. Plants such as trees, which get their carbon dioxide from the atmosphere, therefore contain a small amount of carbon-14. Once a particular part of a plant has been formed, no more new carbon 14 is taken in. The carbon 14 in that part of the plant decays slowly. Let P be the percent of carbon-14 remaining in a part of a tree that grew t years ago (so t years ago, there was 100 percent of the carbon-14 existing in that part of the tree). a.) Write the particular equation expressing P in terms of t. You may assume that the half-life of carbon-14 is 5730 years. A piece of wood some believe to have come from Noah's Ark has 47.93% of its carbon-14 remaining. The Great Flood was supposed to have occurred in 4004 B.C. Is this piece of b.) wood old enouah to have come from Noah's Ark? Iustify vour answer
Radioactive decay
The emission of energy to produce ionizing radiation is known as radioactive decay. Alpha, beta particles, and gamma rays are examples of ionizing radiation that could be released. Radioactive decay happens in radionuclides, which are imbalanced atoms. This periodic table's elements come in a variety of shapes and sizes. Several of these kinds are stable like nitrogen-14, hydrogen-2, and potassium-40, whereas others are not like uranium-238. In nature, one of the most stable phases of an element is usually the most prevalent. Every element, meanwhile, has an unstable state. Unstable variants are radioactive and release ionizing radiation. Certain elements, including uranium, have no stable forms and are constantly radioactive. Radionuclides are elements that release ionizing radiation.
Artificial Radioactivity
The radioactivity can be simply referred to as particle emission from nuclei due to the nuclear instability. There are different types of radiation such as alpha, beta and gamma radiation. Along with these there are different types of decay as well.
