The electron is a fundamental subatomic particle that carries a negative electric charge. It is a spin-½ lepton that participates in electromagnetic interactions‚ and its mass is less than one thousandth of that of the smallest atom. Its electric charge is defined by convention to be negative‚ with a value of −1 in atomic units. Together with atomic nuclei‚ electrons make up atoms; their interaction with adjacent nuclei is the main cause of chemical bonding. The name "electron" comes from

In spite of the fact that Julius Caesar is the protagonist of the play‚ Brutus is probably the most important character who has been active more or less through out the play. Shakespeare consciously builds sympathy among the audience right from the point when the character is first introduced by portraying him as a ‘vexed’‚ helpless soul ‘with himself at war’ torn between patriotism and friendship‚ giving the audience an opportunity to relate to such a “head versus heart” conflict and not only sympathize

Diffusion‚ Osmosis‚ Active Transport There are two ways in which substances can enter or leave a cell: 1) Passive a) Simple Diffusion b) Facilitated Diffusion c) Osmosis (water only) 2) Active a) Molecules b) Particles Diffusion Diffusion is the net passive movement of particles (atoms‚ ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. It continues until the concentration of substances is uniform throughout. Some major examples of diffusion

FREE ELECTRON THEORY Classical free electron theory of metals This theory was developed by Drude and Lorentz and hence is also known as Drude-Lorentz theory. According to this theory‚ a metal consists of electrons which are free to move about in the crystal like molecules of a gas in a container. Mutual repulsion between electrons is ignored and hence potential energy is taken as zero. Therefore the total energy of the electron is equal to its kinetic energy. Drift velocity If no electric

The role and value of play All children and young people need to play. Children ’s play is behavior which is freely chosen‚ self-motivated and personally directed‚ and the impulse to play is in all of us. Through play the child explores the world and its creative potential‚ discovering all the while‚ a flexible range of responses to the challenges‚ she or he encounters. By playing‚ the child learns and develops as an individual and as a member of the community – be it at home‚ the street and area

Ques. Explain the Role Play method. As a trainer where would you like to use the method and what terminal objectives would the method achieve? Ans. Role play is a learning activity in which participants play out roles in a simulated situation. Role plays provide a highly motivational climate because participants are actively involved in a realistic situation. The trainer prepares the role – briefs and briefs the role- players about what they would do before the remaining members of the group. Each
