Differential equation for carbon dating Free date for sex with no sign up
An alpha particle has the same composition as a helium nucleus. There are two protons in the helium nucleus and two neutrons. Since there are two protons, the charge of an alpha particle is two plus.So for representing an alpha particle in our nuclear equation, since an alpha particle has the same composition as a helium nucleus, we put an He in here, and it has two positive charges, so we put a two down here, and then a total of four nucleons, so we put a four here.The rate of metabolism of most drugs follows the rule of first-order kinetics and is independent of the dose.

The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.
