Determination of Young’s modulus with vernier method. To determine Young’s Modulus for copper, two pieces of copper wire seven or eight meters in length are hung from the same support one wire carries a scale of millimeters fixed to it so that the length of the scale is parallel to the wire. A vernier is … Read more

Comparison of masses of two substances using spring balance. Mass is the quantity of matter in a body. More specifically, it is the measurement of the inertia or sluggishness that a body, in the absence of friction, exhibits in response to any effort made to start it, stop it or change in any way from … Read more

Determine the radius of curvature of a convex or concave spherical surface by a spherometer The 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 … Read more
Last Updated: March 19, 2026 at 9:38 pmDetermine the volume of a solid cylinder by slide calipers and screw gauge Volume is the quantity of three-dimensional space enclosed by some closed boundary, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre. … 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
