Paraphrasing 1. What is paraphrasing? - A (more or less) free rewording of an expression or text‚ as an explanation‚ clarification and translation. “Paraphrasing‚ or translation with latitude‚ where the author is kept in view…but his words are not as strictly followed as his sense” (John Dryen‚ preface to his translation of Ovid‚ 1680) - An act or result of rewording (Ex. Simplified version of a legal document) - To make a paraphrase: to translate or define loosely

The Progress of the Atomic structure Different theories about the atomic structure were introduced over time. These theories changed as a result of development of different experiments. Leucippus was the first to introduce the theory of atomism‚ however he didn’t write about his theories in detail. However‚ Democritus‚ his student wrote about the theory of atoms in detail. He theorised that everything was composed of atoms and that atoms are solid and indestructible. He also had a theory that

two small charged spheres having charges of 2 × 10−7 C and 3 × 10−7 C placed 30 cm apart in air? Answer Repulsive force of magnitude 6 × 10−3 N Charge on the first sphere‚ q1 = 2 × 10−7 C Charge on the second sphere‚ q2 = 3 × 10−7 C econd Distance between the spheres‚ r = 30 cm = 0.3 m Electrostatic force between the spheres is given by the relation‚ Where‚ ∈0 = Permittivity of free space Hence‚ force between the two small charged spheres is 6 × 10−3 N. The charges are of same nature. Hence‚ force

Kelvin dropper Theory A normal uncharged piece of matter has equal numbers of positive and negative electric charges in each part of it‚ located close together‚ so no part of it has a net electric charge. The positive charges are the atoms’ nuclei which are bound into the structure of matter and are not free to move. The negative charges are the atoms’ electrons. In electrically conductive objects such as metals‚ some of the electrons are able to move freely about in the object. When a charged
