What do you mean by restivity? How they role in current carrying conductor |
| Answer» \tThe resistivity of a material is the resistance of a wire of that material of unit length and unit cross-sectional area. The unit for resistivity is the ohm-metre.\tThe resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size.\tA good conductor has less resistivity, whereas a bad conductor or insulator has high resistivity.\tThe resistivity of semi-conductors lies between that of conductors and insulators. The resistivity of a metallic conductor increases with an increase in its temperature, whereas the resistivity of a semi-conductor decreases with an increase in its temperature. | |

Explain 10℅law |
|
Answer» Ten percent law means when plant take 100joule energy from the sun and you obtained nutrition from the plant the you get only ten percent energy about 10joule 10% energy transfer law in the food chain is put forth by Lindeman. A pyramid of energy depicts the energy flow form one trophic level to another trophic level in the food chain. According to 10 percent law, 90% of the energy captured from the previous trophic level is lost as heat to the environment and only 10 percent is made available to the next trophic level. Energy flow is from environmental sunlight to producers, producers to primary consumers, primary consumers to secondary consumers and so on. In this consumer take 1percent of energy and other consumer take 10percent of energy |

Explain me the fleming\'s right hand rule & left hand rule?? |
|
Answer» Fleming’s left hand rule:It is used to identify force on a wire carrying current in a magnetic field. Stretch the first three fingers of the left hand mutually perpendicular to each other such that the forefinger points in the direction of magnetic field, the middle finger points in the direction current, then the thumb will indicate the direction of force experienced by the conductorFleming’s right hand rule:Fleming’s right hand rule states that if we stretch the thumb, middle finger and the forefinger of our right hand mutually perpendicular to each other, if the forefinger indicates the direction of the magnetic field and the thumb indicates the direction of motion of conductor, then the (central) middle finger indicates the direction of induced current in conductor coil placed in the magnetic field. U see in yoir hand .this is easiet way |

Hwo is oxygen and carbon dioxide is transport in human beings?? |
|
Answer» Yogita ji ka to kya khana ..har sawal ka jawab h inke pass Exchange of gases takes place between the alveoli of lungs and the surrounding blood capillaries. The two main gases exchanged are oxygen and carbon-dioxide. Oxygen is absorbed by the blood capillaries from the lungs alveoli by diffusion while carbon-dioxide is absorbed by the lungs alveoli from blood capillaries by diffusion.\xa0Transport of oxygen and carbon-dioxide occurs with the help of respiratory pigment called hemoglobin.Hemoglobin, the iron containing respiratory pigment is a red colored pigment of blood, which has a very high affinity for oxygen. Hemoglobin though is purple colored but oxy-hemoglobin is of bright red color. Oxygen is transported from lungs to the body cells in the form of oxy-hemoglobin.Carbon-dioxide is transported from the body cell to the lungs in the forms of carboxy-hemoglobin, carbonic acid, bicarbonates of sodium and potassium. Through the process of breathing |

Why rings of cartilage is present in throat ?? |
|
Answer» Rings of cartilage are present in the throat as it helps the throat from collapsing when there is a low amount of air present. It also helps them to expand when food or water passes through it. Thus it plays an important role in supporting the throat during air blockage and helps in smooth air flow.\xa0 to prevent the walls of trachea to collapse |

What are the reason that m.gandhi started non coorporation movement |
| Answer» Gandhi and the Congress, in their attempt to make common cause with the Muslim League, had supported the Khilafat movement. Gandhi was even elected as the head of the All India Khilafat Committee and advised the Khilafat leaders to practice non-cooperation in order to achieve their objectives. The British government had passed the Rowlatt Act in 1919 which authorised the British government to arrest and imprison any person without trial and convict him in a court. Also, the Act implied severe restrictions on movements of individuals and suspension of the Right of Habeas Corpus. This was seen as a major breach of trust by Indians who were expecting the British to deliver on their promise of providing self-government after the conclusion of the First World War. On top of this, the Jalianwala Bagh massacre happened and the subsequent British reaction to it hardened the Congress resolve to attain self government. As a result of all these developments, Gandhi launched the Non-Cooperation Movement. | |

Why does the container become hot when water is added to calcium oxide |
|
Answer» Because when we add water to calcium oxide it releases a lot of energy. It is a highly exotermic reaction. Bacause lot of heat is produced in this reaction .it is a exothermic reaction When calcium oxide is added to water it forms calciun hydroxide Called slaked lime.\xa0CaO +H2O → Ca(OH)2The reaction between water and CaO is an exothermic reaction. Heat is released during exothermic reaction ,rise in temperature is observed.So the container become hot when water is added to calcium oxide. |

Why carbon has always covelent bond? |
|
Answer» Because of its valency and its valency is 4 Atomic number of carbon is 6.\xa0Electronic configuration of carbon - 2, 4.From the electronic configuration of carbon, it is clear that it has to either gain or lose four electrons, to attain noble gas configuration.Carbon overcomes this difficulty by sharing its electrons with other atoms of carbon or with atoms of other elements. sharing of electrons results in a covalent bond and the shared electrons belong to either of the atoms, this sharing helps in achieving noble gas configuration. Because its valency is 4 |

What is holozoic nutition? |
|
Answer» Holozoic nutrition is the process of obtaining nourishment by the ingestion of complex organic material, which is then digested and absorbed.In this nutrition,\xa0parts of plants or animals or an organism as a whole is ingested and then\xa0digested. Here, animals take the energy containing organic materials, called food, into the gut. After digestion, this food can be absorbed into the body. When this food is decomposed in oxidation reactions, it can release energy to supply for daily uses. It is a nutrition process in which organisms take in hole substances and break it down inside the body. For ex: Amoeba It is that type of nutrition in which animals obtain their food |

Explain:use of synthetic detergent causes pollution of water. |
|
Answer» Detergents contain 20% active ingredients and remaining are sodium sulphate, inorganic phosphates, foaming agents. Phosphates from detergents assist algae and weeds to grow in water, which deplete d oxygen for sea animals. Hence, detergents cause water pollution. as detergent does not mix with water and produces foam which pollutes the river water |

How are types of chromosomes |
|
Answer» In male 23 chromosomes and in female also 23 chromosome total is 46 in a nucleus . For ex. Dioploid etc and like humans who have 22 different ty4of autosomes These tables give the total number of chromosomes (including *** chromosomes) in a cell nucleus. For example, most eukaryotes are diploid, like humans who have 22 different types of autosomes, each present as two homologous pairs, and two *** chromosomes. This gives 46 chromosomes in total. |
