a small plane

What is the resultant surface area of a cone, if a small part is cut off at the top by a plane parallel to the base of the cone? => Surface area of the resultant cone is lesser than the surface area of the original cone or Surface area of the resultant cone is greater than the s..

It consists of two dees or D-shaped metal chambers D 1 and D 2 . The dees are separated by a small distance. The two dees are perpendicular to their plane. P is the position where the ion source is placed. The dees are maintained to a potential difference whose polarity altern..

. Any shiny thing in the night sky may be deceptive. Even UFO experts say that majority of the cases reported are cases of mistaken identity. Natural phenomena like shooting stars, unusual electric glow from the planet Venus, rare formation of clouds or even fog or haze can fool people. Something c..

Even though the laws of friction have been understood since a long time, some properties were understood properly, only after the discovery of atoms and molecules. No matter how well polished two surfaces are, at the atomic level they are never plane. Sometimes, when these extremely well..

A Venn diagram is a pictorial representation of sets by set of points in the plane. The universal set U is represented pictorially by interior of a rectangle and the other sets are represented by closed figures viz circles or ellipses or small rectangles or some curved figures l..

Formation of Our Solar System - Many scientists believe that our solar system was formed from a giant, rotating cloud of gas and dust known as the solar nebula. According to this theory, the solar nebula began to collapse because of its own gravity. Some astronomers speculate that a nearby supernov..

The Earth as a Magnet - About AD1600, William Gilbert, who was a court physician of Queen Elizabeth of England, performed certain experiments using spherical lodestones. When he placed small, pivoted magnetic needles at different positions on this sphere, he found that their behavior was ..

. Energy is not transported across any plane. Note : In the above discussions, while dealing with the interference of waves, it has been assumed that the principle of superposition holds good. Not all waves obey this principle. For e.g., large amplitude waves in fluids and solids interact..
