Right hand flamin rual |
| Answer» Fleming\'s right hand rule states to hold the forefinger, middle finger and thumb of right hand mutually perpendicular to each other so that the forefinger points in the direction of external magnetic field and thumb points in the direction of motion of conductor. Now the direction in which the middle finger is pointed gives the direction of induced current in the conductor.Fleming\'s right hand rule is used to determined the direction of induced current in the conductor when a conductor moves in a region of magnetic field. | |

Should the resistance of an ammeter be low or high ?give reason |
| Answer» 1. Ammeter is used to measure the current in a circuit and it should always be connected in series.2. Resistance means the obstruction caused to the movements of electrons.3. If resistance is more, current will be less.4. So, if ammeter has a high resistance than the current measured will be quite less as compared to actual current which is undesirable.5. If a ammeter has zero resistance , then we will get exact current in the circuit.6. But such thing is not possible as every material in this world has some internal resistance. | |

How metals and non metals react? |
| Answer» \t1Reaction with OxygenMetal + Oxygen→Metal oxide 4Na(s) + O2(g) →2Na2O(s) 4Al(s) + 3O2(g) →2Al2O3 Metals form basic oxides Zn and Al form amphoteric oxides (they show the properties of both acidic and basic oxides) Most of the metal oxides are insoluble in water Some of them dissolve to form Alkali Na2O(s) + H2O(l) →2NaOH(aq)Non-metal + Oxygen →Non-metal oxide C + O2\xa0→CO2 S + O2\xa0→SO2 Non-metals form acidic oxides CO and HO2O are neutral oxides(they are neither acidic nor basic in nature) Non- metal oxides are soluble in water They dissolve in water to form acids SO2\xa0+ H2O →H2SO32Reaction with waterMetals react with water to form metal oxides or metal hydroxide and H2 gas is released. 2Na(s) + 2H2O(l) →2NaOH + H2(g) + heatNon-metals do not react with water, steam to evolve hydrogen gas. Because Non-metals cannot give electrons to hydrogen in water so that it can be released as H2\xa0gas.3Reaction with dilute AcidsMetal + Acid →Metal salt + HydrogenHCl Mg(s) + 2HCl(aq)→ MgCl2(aq) + H2(g)H2SO4 2Na(s) + H2SO2→ Na2SO4(aq) +H2(g)HNO3 Metal + HNO3→\xa0H2\xa0gas is not displaced.Reason-\xa0HNO3\xa0is strong oxidizing agent.Non-metals do not react with acids to release H2\xa0gas Reason-\xa0Non-metals cannot loose electrons and give it to Hydrogen ions of acids so that the gas is released. Mn + 2HNO3→ Mn(NO3)2\xa0+ H2 H2\xa0gas from HNO34Reaction with salt solutionsWhen metals react with salt solution, more reactive metal will displace a less reactive metal from its salt solution. CuSO4(aq) + n(s)→\xa0ZnSO4(aq) + Cu(s)When non-metals react with salt solution, more reactive non-metal will displace a less reactive non-metal from its salt solution. 2NaBr(aq) + Cl2(g)→ 2NaCl(aq) + Br2(aq)\t | |

Why co2 is not necessary for jumans |
| Answer» Carbon dioxide\xa0is essential for internal respiration in a\xa0human\xa0body. Internal respiration is a process, by which oxygen is transported to body tissues and\xa0carbon dioxide\xa0is carried away from them.\xa0Carbon dioxide\xa0is a guardian of the pH of the blood, which is essential for survival.\xa0The cells in\xa0our bodies need\xa0oxygen to stay alive.\xa0Carbon dioxide\xa0is made in\xa0our bodies\xa0as cells\xa0do\xa0their jobs. The lungs and respiratory system allow oxygen in the air to be taken into the\xa0body, while also letting the\xa0body\xa0get rid of\xa0carbon dioxide\xa0in the air breathed out.\xa0A\xa0low CO2 level\xa0can be a sign of several conditions, including: Kidney disease. Diabetic ketoacidosis, which\xa0happens when\xa0your body\'s blood acid\xa0level\xa0goes up because it doesn\'t have enough insulin to digest sugars. Metabolic acidosis, which means your body makes\xa0too\xa0much acid. | |

What do u mean by sadness (by scientific reason) |
|
Answer» Thanx all of u...... Sadness is also a very active, lively, emotion. This may surprise us but the goal of sadness is actually to help us feel strong, alive and courageous in the face of life\'s adversities. It forces us to stop and focus, and so it is common to feel more tired, slower, and less receptive to everything around us. Sadness is an emotional pain associated with, or characterized by, feelings of disadvantage, loss, despair, grief, helplessness, disappointment and sorrow. An individual experiencing sadness may become quiet or lethargic, and withdraw themselves from others. Decreasing the amount of dopamine |

Write down the preparation method and uses of compound (washing soda). |
| Answer» Washing soda is a whitish, odourless powder. Its\xa0chemical formula is Na2CO3\xa0and is better known as\xa0sodium carbonate. It is hygroscopic in nature that is, it absorbs moisture from the air. It is highly soluble in water and forms strongly alkaline water solution.Washing soda is synthesized through\xa0Solvay’s process.\xa0Solvay’s process involves the reaction of sodium chloride, ammonia and carbon dioxide in water. Carbon dioxide involved is produced through calcium carbonate and the calcium oxide left is used in recovering ammonia from\xa0ammonium chloride.At first, sodium bicarbonate is obtained which is then converted to sodium carbonate on heating. Finally, washing soda is produced by recrystallization of sodium carbonate.\tNaCl\xa0+\xa0NH3\xa0+\xa0CO2\xa0+\xa0H2O →\xa0NaHCO3\xa0+\xa0NH4Cl\t2\xa0NaHCO3\xa0→\xa0Na2CO3\xa0+\xa0H2O\xa0+\xa0CO2\tNa2CO3\xa0+ 10H2O →\xa0Na2CO3.10H2O | |

Differentiate between electrical and chemical coordination |
| Answer» The biggest\xa0difference between\xa0the two is that the\xa0nervous\xa0system uses electrical impulses to send signals through neurones, whereas the\xa0hormonal\xa0system uses\xa0chemical\xa0messengers transported into blood plasma to target cells.\xa0The\xa0main\xa0difference between chemical\xa0synapse and\xa0electrical\xa0synapse is that in a\xa0chemical\xa0synapse,\xa0the\xa0nerve impulse passes chemically by means\xa0of\xa0neurotransmitters whereas an\xa0electrical\xa0synapse is connected through channel proteins. Nerve impulses pass through\xa0the\xa0membrane\xa0of the\xa0axon as an\xa0electrical\xa0signal.\xa0A\xa0chemical synapse\xa0is a gap\xa0between\xa0two neurons where information passes chemically,\xa0in the\xa0form of neurotransmitter molecules. An\xa0electrical synapse\xa0is a gap which has channel proteins connecting the two neurons, so the\xa0electrical\xa0signal can travel straight over the\xa0synapse. | |

How the amount is by urine produced regulated ? |
| Answer» The amount of urine produced depends on the amount of excess water and dissolved wastes that are present in the body. Other factors such as habitat and hormone such as Anti-diuretic hormone (ADH) also regulates the amount of urine produced. When excess water is more in the body, diluted urine is excreted whereas when the excess water is less, the urine is concentrated. | |
