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 ..

weighing with a spring balance or a pan balance is possible due to damping of the oscillations otherwise it would not have been possible to read the scal..

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..

S.I unit of thrust is Newton (N). Now let us see whether there is a relation between the force applied (thrust) and the area on which it is acting..

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..

Oersted's experiment shows that a current carrying wire exerts a force on a magnetic needle and deflects it from its usual north-south positio..

There were 50 software companies in Smart City Software Park in the year 2000. Subsequently, the number of software companies increased by 20 each year. Write a linear model for the number of software companies. What could be the number in the year 2008? => l = 20 t + 50, 210 or l = 20( t..
