Determine the radius of curvature of a convex or concave spherical surface by spherometer Radius of curvature: The distance from the center of a circle or sphere to its surface is its radius. For other curved lines or surfaces, the radius of curvature at a given point is the radius of a circle that mathematically … Read more
Last Updated: March 19, 2026 at 5:07 pmDetermine the volume of a solid cylinder by using Archimedes principle Archimedes: When we think of the great scientists and mathematicians of the ancient world, who have contributed greatly to today’s inventions and researches, who could forget Archimedes. In the hearts and minds of scientists Archimedes occupies the same respectable position as Newton and Gauss. … Read more
Last Updated: March 19, 2026 at 5:08 pmDetermine the specific gravity of Alum by Hydrostatic balance Alum is both a specific chemical compound and a class of chemical compounds. The specific compound is the hydrated potassium aluminium sulfate (potassium alum) with the formula KAl(SO4)2·12H2O. More widely, alums are double sulphate salts, with the formula AM(SO4)2·12H2O, where A is a monovalent cation such … Read more
Last Updated: March 19, 2026 at 5:07 pmDetermine specific gravity of Kerosene by specific gravity bottle Two methods are commonly used for determining the specific gravities of liquids. One method uses the hydrometer, an instrument that gives a specific gravity reading directly. A second method, called the bottle method, uses a “specific-gravity bottle,” i.e., a flask made to hold a known volume … Read more
Last Updated: March 19, 2026 at 11:54 pmDetermination of g by Simple Pendulam In physics, gravitational acceleration is the acceleration on an object caused by gravity. Neglecting friction such as air resistance, all small bodies accelerate in a gravitational field at the same rate relative to the center of mass. This equality is true regardless of the masses or compositions of the … Read more
Last Updated: March 19, 2026 at 5:08 pmThe speed of sound is the distance travelled during a unit of time by a sound wave propagating through an elastic medium. In dry air at 20 °C (68 °F), the speed of sound is 343.2 metres per second (1,126 ft/s). This is 1,236 kilometres per hour (768 mph), or about one kilometer in three … Read more
