A steady current (DC) cannot carry any intelligence. This is because there is no variation in it. However, if it can be changed in some meaningful sequence, then it can be made to carry information (or intelligence). A continuous as wave as such also cannot carry intelligence. This is because it i..

fig.12.1 - Space Models of 2-Butenes Note that the atoms are arranged in two different ways in I and II. The two CH 3 groups lie on the same side in I and on the opposite sides in II. When two similar atoms or groups lie on the same side, the isomerism is called cis isomerism a..

J. J Thomson the discoverer of the electron believed that the atom is a uniform sphere of positive charge with electrons (raisins) embedded in it. This model explained the electrical neutrality of atom, but it failed to explain how these fundamental particles were arranged in..

The atom of an element consists of a small, positively charged nucleus in the centre, which carries almost the entire mass of the atom. The electrons are revolving around the nucleus at high speed. The number of electrons in an atom is equal to the number of protons. Hence it is electr..

It is a double helix with two right handed helical polydeoxy ribonucleotide strands twisted around the same central axis. The two strands are antiparallel. The phosphodiester linkages of one of these strands runs in 5' to 3' direction while the other strand runs in 3' to 5' direction. The base..

(i) Every atom consists of a nucleus containing the entire +ve charge. The whole mass of atom is concentrated at this core. (ii) The size of the nucleus i.e., 10 - 1 5 m is very small compared to the size of the atom (i.e., 10 - 1 0 m). (iii) The atom as a whole is electrically n..

Which of these is best modeled by a sheet of paper? => plane or quadrant or line or point..

. On passing through A, only the vertical vibration of the string appears and these continue to go through B and come out finally. When the slit of board B is placed perpendicular to A, no vibrations appear to come out of B, although vibrations appear in the region between A and B. We therefore say..

It could not explain the line spectrum of multi electron atoms. This model failed to explain the effect of magnetic field on the spectra of atoms (Zeeman effect). The effect of electric field on the spectra could not be explained by Bohr's model (Stark effect)...
