small group dynamics

Several types of microphones depend for their action upon the voltage induced in a conductor moving in a magnetic field. The dynamic or moving-coil micro- phone contains a small coil attached to a diaphragm, so arranged that when the diaphragm vibrates, the coil moves back and ..

. After this no change in concentration occurs provided the temperature of the reaction mixture is kept constant. Thus at equilibrium the reaction does not stop but the system acquires constant observable properties because of the equal rates of forward and backward reactions. Thus the equilibrium ..

All the genes located on a particular chromosome, form a linkage group. Since the genes present on a particular chromosome have their alleles located on its homologous chromosome, genes on a pair of homologous chromosomes. Hence, the number of linkage groups corresponds to the n..

Similar physical and chemical properties are shown by elements in a group. However the first member of each group differs from its succeeding members (called congeners). This mainly occurs because of, The small size of the atom and its ion. The high ionization en..

The elements helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn) are grouped together in Group 18 of the Periodic Table. All of these are gaseous under ordinary conditions of temperature and pressure. The last number of the group, radon is obtai..

According to the dynamic particle model all states of matter are made up of tiny particles and matter as a result is an aggregation of very small particles. Nevertheless, the state of aggregation of particles is different in different substances. Some characteristic features of..

The elements belonging to this group are more electronegative than elements of group 13. It is because these have a small size. The electronegativity value decreases from top to bottom in the group..

Characteristics of Particles of Matter - According to the dynamic particle model all states of matter are made up of tiny particles and matter as a result is an aggregation of very small particles. Nevertheless, the state of aggregation of particles is different in different sub..

. After fertilisation, the fertilised ovum trickles down into the uterus for implantation. Cleavage is the process which transforms the fertilised ovum into a sphere of closely aggregated cells. The fertilised ovum divides repeatedly in close succession to form blastomeres. Cleavage divisions do no..

The extent to which a solute dissolves in any solvent is termed as its solubility. Different substances have different solubility, some dissolve more and some less. A solution containing the maximum amount of solute at a fixed temperature and pressure is called a saturated solution. A saturated sol..
