definition of assignment problems

Energy is a number that we associate with a system of one or more objects. If a force acts on one of the objects, making it move, then the number changes. After countless experiments, scientists and engineers realised that if the scheme by which we assign these energy numbers is planned ..

Lens Formula - The relationship between distance of the object (u), distance of the image (v) and focal length (f) of the lens is called lens formula or lens equation. This lens formula is applicable to both convex and concave lenses. Note : Points to be remembered while using the lens formula. The..

Trigonometry is a fascinating tool, initially conceived from chords in a Unit-Circle it has wide applications and whenever space is involved Trigonometry is used irrespective of the area of interest. Trigonometry involves the study of concepts like the Sine, Cosine, Tangent and Cotangent. Get best..

Hydrogen combines with non-metals like carbon, silicon, etc. to from covalent compound like halogens. Examples: CH 4 and CCl 4 . Remember : In 1766, Henry Cavendish, an English chemist, discovered hydrogen, by treating iron with dilute sulphuric acid. He also proved that when hydrogen is bur..

It is that characteristic of a musical sound by which a shrill sound can be distinguished from a grave one, even though the two sounds may be of the same intensity. It is also defined as that characteristic of sound by which the ear assigns it a place on a musical scale. When a..

The electrostatic field of an ion is nondirectional.Each positive ion attracts several negative ions around it depending upon its size or radius and vice-versa ,resulting in a three dimensional solid aggregate called an ionic crystal in which oppositely charged ions alternate in regular,continuous..

All elements beyond uranium (Z=92) are synthesized in the laboratories and are known as 'trans uranium elements'. The elements, beyond fermium (Z=100) are known as 'trans fermium elements'. These elements have atomic numbers 101 onwards. Elements like fermium (Z=100), mendelevium (Z=101), nobelium ..

A linear equations in two variables x and y is of the form ax + by + c = 0 ( ) where a, b, c are real numbers. To find a solution for this equation, we can assign any value for one of the variables and find the value of the other variable such that the two sides of the equation are e..

The relationship between distance of the object (u), distance of the image (v) and focal length (f) of the lens is called lens formula or lens equation. -------- Lens formula This lens formula is applicable to both convex and concave lenses. Note: Points to be remembered while using ..

IUPAC Nomenclature for Elements with Z > 100 - All elements beyond uranium (Z=92) are synthesized in the laboratories and are known as 'trans uranium elements'. The elements, beyond fermium (Z=100) are known as 'trans fermium elements'. These elements have atomic numbers 101 onwards. Elements like ..
