="tblcel">The rod AB gets displaced. The rod AB is connected in series to a battery, a key and a rheostat Switch on the current Procedure Observation Repeat the experiment by changing the direction of flow of current. The rod AB gets displaced in the reverse directio..

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..

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 artefa..

+ so that, sodium rapidly diffuse along the concentration gradient and the electrical gradient. Now sarcolemma becomes electropositive inside and electronegative outside. This new potential difference is called action potential. Such sarcolemma is called depolarised . Action potential stimulates th..

. As the bob is displaced to one end, it gains potential energy and as it is released from rest, it starts gaining kinetic energy till it reaches the mean position. Kinetic energy possessed by the pendulum is maximum at the mean position and zero at the extreme positions, whereas the potential ener..

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 ..

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..

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..

The dates 24, 17, 10, 3, and 31 were Sundays in a month. Arrange the dates in ascending order. => 3, 10, 17, 24, and 31 or 31, 24, 17, 10, and 3 or 10, 17, 24, 3, and 31 or none of these..
