All radioactive decays follow first order kinetics. Therefore, the half-life of a radioactive element is independent of the amount of sample. With the help of half-life values of a suitable radioisotope of an element, which is present in a rock, or in an artefact, the age of the rock and the ..

The age of fossils of plant or animal origin can be determined by carbon dating technique developed by Willard Libby in 1949. The radioactive isotope of carbon ( 6 C 1 4 ) is used to determine the date at which an animal or plant had died. Carbon Dating The metho..

Radiocarbon dating of historical wooden - derived objects is based on the knowledge that the cosmic ray intensity (responsible for 1 4 C production) has been practically constant for thousands of years. 1 4 C is formed in the upper atmosphere by the action of cosmic radiation ..

Radio Carbon Dating - Radiocarbon The 1 4 C so produced is eventually converted into CO 2 , which in turn is incorporated into plants and trees by the process of photosynthesis and then finds way into animals, which eat pla..

Radiocarbon The 1 4 C so produced is eventually converted into CO 2 , which in turn is incorporated into plants and trees by the process of photosynthesis and then finds way into animals, which eat plants. As there is a natural plant-animal cycle, an equilibrium is set up and all living matter cont..

Use the calendar shown to find the date on the first Monday of the month. => 1 st or 14 th or 7 th or 21 st..

There are a small number of radioisotopes of low proton number, which occur naturally. They are produced by bombardment by radiation from outer space (cosmic rays). The most well known of these is radioactive carbon-14, which is produced when nitrogen is bombarded by neutron..

Whose score is twice the score of John? => Edd or Bob or Mathew or John..
