Does carbon dating work
Thus, the mixture taken as a whole will not decay by halves.
A biological half-life or elimination half-life is the time it takes for a substance (drug, radioactive nuclide, or other) to lose one-half of its pharmacologic, physiologic, or radiological activity.
Consider a mixture of a rapidly decaying element A, with a half-life of 1 second, and a slowly decaying element B, with a half-life of 1 year.
In a couple of minutes, almost all atoms of element A will have decayed after repeated halving of the initial number of atoms, but very few of the atoms of element B will have done so as only a tiny fraction of its half-life has elapsed.
The number at the top is how many half-lives have elapsed.
Is it true that faster aging of the twin who stayed at home happens only when the other twin’s spaceship is accelerating/deceleration (btw, does it matter whether he is accelerating or decelerating? Consequently, do they age at the same rate when the spaceship moves inertially?
The accompanying table shows the reduction of a quantity as a function of the number of half-lives elapsed.
