Application radioactivity carbon dating

Describe radioactivity and its characteristics such as half life and decay rate 3.

Apply and solve day life problem regarding to half life and rate of decay of radioactive source 4.

For example, in 1991, two hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain.

Later called Ötzi the Iceman, small samples from his body were carbon dated by scientists.

Thus, the nuclear decay is independent of the past history of a sample.

ii) Component deflected leftward is the positively charged particles (α) iii) Component deflected rightward is the negatively charged particles (β-).

After three half-lives, half of before have decayed and N0/8 are left.

In general, after n half-lives, the number of radioactive nuclei remaining is N0/2n.

    Last year, Leigh Bush dropped his mixtape taking people by storm showing that Sammie (at the time) is one of the best R&B artist out.
