The frequency or the swing rate of a pendulum depends on the length. The longer the length of the pendulum, the slower it swings. Conversely,... View Article
It is considered a rotation if an object revolves around an internal axis (like the Planet turns around its axis). It's called a revolution when... View Article
A coulomb is defined as the volume of electricity transported by a current of one ampere in a single second. It is roughly equal to 6.24 x 1018... View Article
A transformer is an electrical device designed to switch from one voltage to another alternating current. It can be built for voltages of “step... View Article
The ph of HCl is 3.01. They dissociate into H+ ions and Cl- ions as HCl molecules dissolve. HCl is a strong acid and it nearly fully dissociates.... View Article
The aluminium chemical formula is Al. The molar mass is 26.98g/mol. Metallic aluminium is present in its elemental state (the most fundamental... View Article
Energy is acquired through fission by breaking large atoms, such as plutonium, into lighter atoms, such as iodine, caesium, strontium, xenon, and... View Article
When a material is broken up into several parts, entropy grows. The method of dissolving increases entropy and when a solution is produced, the... View Article
Electrophiles are species poor in electrons and can accept an electron pair from species rich in electrons. Carbocations and carbonyl compounds... View Article
The biggest distinction between the ammeter and the voltmeter is that the ammeter tests the current flow, while the emf or voltage is determined... View Article
At the middle, a convex lens is thicker than at the sides. Rays of light are brought closer together by going through the lens (they converge). A... View Article
Polymer, which is part of a class of natural or synthetic compounds consisting of very large molecules, called macromolecules, called monomers,... View Article
Potassium Permanganate is a flexible and potent oxidant which can be used by overt or indirect titration to classify many compounds. A special... View Article
Halogenes with low dissociation energies and high negative electron gain enthalpies are strongly electronegative. They therefore have a high... View Article
As the surface particles of the adsorbent are unstable, adsorption is an exothermic mechanism and as the adsorbate is adsorbed on the surface,... View Article
The SI unit of impulse is the newton second (Nâ‹…s). The impulse applied to an object, often in the same direction, causes an equal vector shift in... View Article
Valency is the strength of an element to blend. Elements have the same valency in the same periodic table group. How many electrons are in the... View Article
As the distance moved by the tip of the screw when turned through one division of the head scale, the least count of the screw is specified. The... View Article
In physics, a force constant is another term for a spring constant, as defined by Hooke's law. It is a proportionality constant, more precisely.... View Article
A magnetic field is a vector field that determines the magnetic effect on electric charges, electric currents, and magnetic materials that shift.... View Article
