In the case of rapid growth, we may choose the exponential growth function: is a positive constant that determines the rate (percentage) of growth.
We may use the exponential growth function in applications involving doubling time, the time it takes for a quantity to double.
Immer wenn ein Lebewesen stirbt, beginnt eine Stoppuhr zu laufen.
Die Wissenschaft kann diese Uhr ablesen und so das Alter eines Fundes ermitteln. Source unknown — possibly das Museum für Vor‑ und Frühgeschichte (the Museum for pre‑ and early history) in Berlin.
Half-life is defined as the amount of time it takes a given quantity to decrease to half of its initial value.
The term is most commonly used in relation to atoms undergoing radioactive decay, but can be used to describe other types of decay, whether exponential or not.
The half-life of carbon-14 is approximately 5,730 years, and it can be reliably used to measure dates up to around 50,000 years ago.
This rare, unstable isotope is produced from ordinary nitrogen 14.
In earth's upper atmosphere, on the edge of what is commonly called outer space, light atomic nuclei from unknown sources outside of our solar system traveling at speeds approaching the speed of light called rain down continuously.
We may use the exponential decay model when we are calculating half-life, or the time it takes for a substance to exponentially decay to half of its original quantity.
We use half-life in applications involving radioactive isotopes.
