Determine 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

Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance,[1] one arrives at the usual mathematical equation that describes this relationship: where I is the current through the conductor in … Read more
Last Updated: March 19, 2026 at 5:08 pmRefraction is the change in direction of a wave due to a change in speed at the boundary between two media of different density. The Latin word “fract” in refraction means to break. Refraction is the “breaking or bending” of waves as it travels to a different density media. The absolute index of refraction of … Read more
Last Updated: March 19, 2026 at 9:15 pmA vibrating sample magnetometer or VSM is a scientific instrument that measures magnetic properties, invented in 1955 by Simon Foner at Lincoln Laboratory MIT. The paper about his work was published shortly afterward in 1959[1] A sample is placed inside a uniform magnetic field to magnetize the sample. The sample is then physically vibrated sinusoidally, … Read more
Last Updated: March 19, 2026 at 5:08 pmA practical electrical power source which is a linear electric circuit may, according to Thévenin’s theorem, be represented as an ideal voltage source in series with an impedance. This resistance is termed the internal resistance of the source. When the power source delivers current, the measured e.m.f. (voltage output) is lower than the no-load voltage; … Read more
