What is Rayleigh elastic scattering? |
| Answer» Rayleigh scattering\xa0is the elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the light. Elastic scattering means that incident wavelength and scattered wavelength are the same.\xa0Rayleigh scattering is inversely proportional to the fourth power of wavelength, which means that the shorter wavelength of blue light will scatter more than the longer wavelengths of green and red light. This gives the sky a blue appearance. | |

What are Einstein\'s field equations |
|
Answer» Didi your answer was excellent but I am sorry to say that the answer posted by you didn\'t satisfy me as I want to know what are the equations but not the history of the equations The Einstein Field Equation (EFE) are also known as Einstein’s equation. There are the set of ten equations extracted from Albert Einstein’s General Theory of Relativity. The EFE describes basic interaction of gravitation. The equations were first published in 1915 by Albert Einstein as a tensor equation.The Einstein field equation are determined by the spacetime geometry with the presence of energy-mass and linear momentum. This is similar to the Maxwell’s equation where, the electromagnetic fields are identified by currents and charges. |

How the current flows in a wirw |
|
Answer» Current flow in wire due to flow of electron. CurrentFlows in a wire through a closed circuit.this is as follow when switch is on current starts flowing from positive terminal to negative terminal and electron flows from negative terminal to positive terminal this way whole the circuit complete this process goes on and while flowing when the electron meets with a resistance ie fan,bulb and so on then the energy of electron get converted in different and work is done . Free electron are the carrier of charge.not all electron |

Defination working of human eye |
| Answer» The human eye is a spherical structure which fits in the eye socket in the skull bone. There are following main parts in the human eye.\tPupil: Pupil is the round black spot in front of eye. It regulates the amount of light entering the eyes. Pupil works like aperture of a camera. In case of dim light pupil dilate to allow more light to enter the eyes. In case of strong light pupil constrict allowing less light to enter.\tIrish: Irish is made of muscles. They control the size of opening of pupil.\tLens: Lens lies just behind the pupil. Lens becomes thin to increase its focal length. This enables us to see distant objects clearly. To focus on nearer objects, lens becomes thick to decrease its focal length. But there is a limit. The minimum distance of clear vision is 25 cm. Below this distance, we cannot see things clearly.\tRetina: Retina works like a screen or camera film. Retina is full of light and colour sensitive cells. These cells, upon receiving image send electrical signals to the brain, which processes these information to make a mental image of what we see. The photoreceptor cells in the eye are of two types, viz. rod cells and cone cells. The rod cells are sensitive to dim light. The cone cells are sensitive to bright light and colour. | |

Why is voltmeter connected in parallel. |
|
Answer» It has high resistance when it is connected in parallel then equivalent resistance willbe very low ie a voltmeter of resistance 2000ohm when we calculate the equivalent resistance then 1/2000=very low in decimal as you can assume if it is connected in series the equivalent resistance be 2000ohm which is very high Becoz having high resistence To over come frome it Voltmeter connected in parallel because for measurning voltage Because it has high resistance. Sorry bro, i don\'t know |

Types of kingdom |
|
Answer» In 1859s Robert Whittaker gave 5 kingdoms namely:-• Monera.• Protista.• Fungi.• Plantae.• Animalia. Kingdoms are divided into subgroups at various levels. The following flowchart shows the hierarchy of classification.Kingdom → Phylum → Class → Order → Family\xa0→ Genus → SpeciesKingdom Monera: These organisms are prokaryotic and unicellular. They do not have a well-defined nucleus and also lack cell organelles. Some organisms show the presence of cell wall while there are others without a cell wall.Kingdom Protista: Organisms grouped under Kingdom Protista are all unicellular, but eukaryotic organisms. These are the simplest forms of eukaryotes that exhibit either autotrophic or heterotrophic mode of nutrition.Kingdom Fungi: Heterotrophic, Multicellular and Eukaryotic organisms are grouped under Kingdom Fungi. Their mode of nutrition is saprophytic as they use decaying organic matter as food.Kingdom Plantae:These are Eukaryotic, Multicellular organisms with a cell wall that is made up of cellulose. They are autotrophs and synthesize their own food through the process of photosynthesis. This kingdom includes all plants.Kingdom Animalia: This Kingdom includes organisms that are Multicellular, Eukaryotic, without the presence of cell wall. They have a heterotrophic mode of nutrition.\xa0 |

How do elements occur in nature |
|
Answer» Some few elements occur naturally in their elemental form: examples include carbon (as coal or as diamond) as well as elemental gold in nuggets. Gases found in the atmosphere occur as an elemental mixture: mostly dinitrogen and dioxygen, which we are breathing right now. Of course, most elements are found as constituents in chemical compounds: for instance as carbon dioxide in the atmosphere, or as silicates in the soil - oxygen compounds are very common.

Define the term Bio diversity hotspotWater harvesting Sustainable management |
| Answer» \tBiodiversity is the diversity of plant and animal life found in a particular area. It also deals with the inter-relationship and interaction with their environment. Food chains are maintained in order to maintain continuity of life.\tBiodiversity is the various kinds of species of organisms and their range found in a particular area. Forests, wetlands, coral reefs, etc. have a rich biodiversity and are therefore considered as biodiversity hotspots.\tRainwater harvesting is a technique used for collecting, storing, and using rainwater for landscape irrigation and other uses. The rainwater is collected from various hard surfaces such as roof tops and/or other types of manmade above ground hard surfaces.\tSustainable development means the development which does not harm the environment and the recent development does not overlook the needs and requirement of the future generations. | |
