What are optical fibres? |
|
Answer» Thanks for your answers?✌ An\xa0optical fiber\xa0is a flexible, transparent\xa0fibermade by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. ...\xa0Optical fibers\xa0typically include a core surrounded by a transparent cladding material with a lower index of refraction. Optical fiber is the technology associated with data transmission using light pulses travelling along with a long fiber which is usually made of plastic or glass. Metal wires are preferred for transmission in optical fiber communication as signals travel with fewer damages. Optical fibers are also unaffected by electromagnetic interference. The fiber optical cable uses the application of total internal reflection of light. The fibers are designed such that they facilitate the propagation of light along with the optical fiber depending on the requirement of power and distance of transmission. Single-mode fiber is used for long-distance transmission, while multimode fiber is used for shorter distances. The outer cladding of these fibers needs better protection than metal wires. An optical fiber is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than of a human hair. |

Why is colour of sky blue during day time? |
|
Answer» SKY BLUE KYU HOTE HAI ,OUR ATMOSPHERE IS MADE UP OF VERY TINY PARTICLES , IT CONTAIN 78% OF NITROGEN AND 21% OXYGEN , THE RAY OF SUN WHICH PASSES THROUGH THE ATMOSPHERE WHICH CONTAIN ALL SEVEN COLOUR BUT THE THREE OF THEM(VOILET , INDIGO AND BLUE) ARE SCATTERED ON ATMOSPHERE BECAUSE OF SHORT WAVELENGTH .THE VOILET AND INDIGO HAS SMALLEST WAVE LENGTH , BOTH SCATTER ON THE TOPEST LAYER OF ATMOSPHERE AND ONLY BLUE ARRIVE TO OUR EYES. (VIBGYOR) by this you can refer that vilot, indigo and blue have less wavelength . And sun is nearer to our earth so because of this atmosphere can\'t refract much amount of light in day time. And same happens with sunset and surise time red has greater wavelength than blue and any other colour . That time sun is far from us because of that all colour refract only red color don\'t refract by this you can say that in sunrise and sunset time the sky is red Because, In sky there is small particle present , and blue colour is scattered in small particle . We know that white colour is made up of seven colour VIBGYOR . ;Therefore colour of sky blue during day time. |

Why does corban not form ionic compound? |
|
Answer» Simple reason is it valency is 4. So it requires more energy to donate or take electrons which it can\'t afford. The ionic compound can only perform by donating and gaining of electrons but the carbon (first tetravalent compound in Periodic table) has not sufficient proton (p^+ = 4 ) to stable the 8 electrons( gain 4 and complete octate) and it cannot donate also because it has 4 electrons to donate but due to high intermolecular force it cannot. So it only form covalent compounds by sharing electrons. The electronic configuration of carbon atom is 1s2\xa02s2\xa02px1\xa02py1\xa0and has four valence electrons. In order to form ionic compound, it has to either lose four electrons or gain four electrons. Since very high energy are involved in doing so. Carbon does not form ionic compounds. It completes its octet by sharing of electrons and forms covalent compounds. |

Why Doberniers Triads became failed? |
|
Answer» Drawbacks of Dobereiner\'s classification of elements was that it\xa0failed\xa0to arrange all the then known elements in the form of\xa0triads\xa0of elements having similar chemical properties. ... Dobereiner also\xa0failed\xa0to explain the relation between atomic masses of elements and their chemical properties. Limitations of Dobereiner’s classification of elements was that it failed to arrange all the then known elements in the form of triads of elements having similar chemical properties. His classification was not applicable to all known elements but was limited only to a few elements. For example: nitrogen, Phosphorus and arsenic have similar chemical properties but they do not constituent a Dobereiner’s triad. Dobereiner’s could identify only three triads from the elements known at that time. So his classification of elements was not much successful. Dobereiner also failed to explain the relation between atomic masses of elements and their chemical properties.\xa0 Doberneir traid was got failed because his law was not applicable for all the elements... |

Why should curd and sour substances should not be kept in copper and brass vessels? |
|
Answer» Curd and sour substances are all acidic and Copper &Brass are the most reactive metals. When these substances are kept in contact with reactive metals , they highly react with these metals . This result in the change of taste of sour substances and these metals gets corrode. Copper is a metal which can react with an acid to form metal oxides, the same goes for brass too since it is an alloy of copper and zinc, and since curd contains lactic acid it can react with the metal in copper and brass and can make metal oxide hence that can cause food poisoning.... Similarly since sourness is a property in acids they can also cause food poisoning if kept in any metal container for a very long time. Curd and sour substances contain acids. Acids react with metals to produce salt and hydrogen gas. So, if such substances are kept in copper container, the acid will react and the container will be corroded. |

What are the causes of green house effect? |
|
Answer» Thanks for your answers? ✌ green house is anenclosed region made of glass in whichdelicate plants are kept for growing. Sun\'s rays pass though the glass in the greenhouse. The infra red rays reelected by earth surface inside the greenhouse are not allowed to escape due to the glass walls Thus, air inside the green house becomes warmer. In a similar manner, atmosphere acts like a green house wall for earth. The gases such as co2, methane, ozone, etc. Are green house gases. These allow sun\'s rays to enter the earth\'s atmosphere and reach earth surface. But they prevent the reflected infra red rays from escaping the earth. This is called green house effect.... Global warming refers to the increasing temperature of the Earth’s climate system and its related effects. Scientific evidence has conclusively proven that the Earth’s temperature is in fact rising and has risen by 0.85oC. This has an impact has affected different regions differently. The effects include rising sea levels, retreating glaciers, loss of sea ice in the poles, warming global temperatures, changing precipitation, expansion of deserts, etc.This raises significant threats for humans such as food security from decreasing crop yields, submergence of a low-lying area due to the rising sea. To prevent irreversible damage to the delicate ecosystems on Earth, scientists have decided that global warming should be limited to a maximum of 2.0oC relative to pre-industrial levels. The greenhouse effect plays an important role in the rising temperature. And hence to restrict global warming we need to limit the greenhouse effect and the gaseous emissions that cause the greenhouse effect.Fourteen of the fifteen years in the 21st\xa0century have been the hottest years on record with constant occurrences of extreme weather, cyclones, droughts, floods, etc. All these events are some way or the other have an association with the greenhouse effect and global warming. |

What is lymphatic system? |
|
Answer» Tysm... 1) Lymphatic system consists of lymph capillaries, lymph vessels, lymph nodes and lymph glands.2) To supply nutrients to the cells (tissues), the liquid portion of the blood with nutri¬ents flows out of the capillaries. This is called tissue fluid.3) To transport the tissue fluid into the main blood stream, a separate system called lymphatic system is present.4) Lymph is the vital link between blood and tissues by which essential substances pass from blood to cells and excretory products from cells to blood.5) Lymph is the substance that contains blood without solid particles.6) Tissue fluid is the substance which contains lymph present in the tissues.7) From intercellular spaces, lymph goes into lymphatic capillaries.8) Lymphatic capillaries join to form large lymph vessels which finally open into larger veins.9) Lymph flows only in direction, that is from tissues to heart through veins.Functions of Lymph:a) Lymph carries digested and absorbed fats from small intestine to different tissuesof the body. .b) It helps in removing Waste materials from the cells in the body to drain into blood.c) Lymph protects cells in the tissues from infection. |

What are the functions of brain? |
|
Answer» Thanks for your answer? ✌ The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus . The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons and medulla.Cerebrum:The cerebrum is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebral cortex is divided into four sections, called "lobes": the frontal lobe, parietal lobe, occipital lobe, and temporal lobe.\tFrontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving\tParietal Lobe- associated with movement, orientation, recognition, perception of stimuli\tOccipital Lobe- associated with visual processing\tTemporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speechThalamus-It is a large mass of gray matter deeply situated in the forebrain at the topmost portion of the diencephalon. The structure has sensory and motor functions. Almost all sensory information enters this structure where neurons send that information to the overlying cortex.Hypothalamus-It is a part of the diencephalon, ventral to the thalamus. The structure is involved in functions including homeostasis, emotion, thirst, hunger, circadian rhythms, and control of the autonomic nervous system. It also controls the pituitary.Midbrain-It is involved in functions such as vision, hearing, eyemovement, and body movement.Cerebellum\xa0- The cerebellum has two hemispheres and has a highly folded surface or cortex. This structure is associated with regulation and coordination of movement, posture, and balance.Pons-\xa0It is involved in motor control and sensory analysis. It has parts that are important for the level of consciousness and for sleep.Medulla Oblongata-This structure is present between the pons and spinal cord. It is responsible for maintaining vital body functions, such as breathing and heartrate. |

Explain the mechanism of *** determination in humans.? |
|
Answer» Human beings have XX_XY *** determination system. In this, the males have XY *** chromosomes. They produce two types of gametes having X and Y chromosome. The females have XX chromosome. They produce only one type of gamete having X chromosome. The *** of a child is determined by the type of chromosome he/she receiving from the father. If sperm is having X chromosome, then the child will be a girl. If sperm is having Y chromosome, then the chilld will be a boy. The Y chromosome carries factors responsible for triggering male development. The X chromosome carries factors responsible for triggering female development. *** determination in humans is of XX-XY types. Human has total 23 pairs of chromosomes; 22 pairs of autosomes and one pair of *** chromosomes. In humans, females are homomorphic (XX) and males have heteromorphic *** chromosomes (XY).\xa0During meiosis, all the gametes produced by females contain only the X chromosome (22 A + X), whereas males produce two kinds of gametes, 1/2 gametes with X - and 1/2 with Y-chromosome (22 A + X and 22 A + Y). Fertilization of egg (22 + X) with sperm carrying 22+X chromosomes results in female child (44A + XX). Fertilization of egg (22 + X) with a sperm carrying 22+Y chromosomes results in a male child (44A + XY) |
