Difference between AC and Dc generator and its workings and uses? |
|
| Answer» | \tAC generator is a mechanical device which converts mechanical energy into AC electrical power.DC generator is a mechanical device which converts mechanical energy into DC electrical power.In an AC generator, the electrical current reverses direction periodically.In a DC generator, the electrical current flows only in one direction.In an AC generator, the coil through which the current flows is fixed while the magnet moves. The construction is simple and costs are less.In a DC generator, the coil through which the current flows rotates in a fixed field. The overall design is very simple but construction is complex due commutators and slip rings.AC generator does not have commutators.DC generators have commutators to make the current flow in one direction only.AC generators have slip-rings.DC generators have split-ring commutators.Since slip-rings have a smooth and uninterrupted surface, they do not wear quickly and are highly efficient.Both brushes and commutators of a DC generator wear out quickly and thus are less efficient.\t | |

Aluminium is reactive metal so why it is use for packing food |
|
Answer» As a layer of oxide is formed on aluminium which prevents from corrosion. Therefore the food indgredeint do not react with aluminium. Aluminium is quite reactive, when it is kept in air or oxygen for some time, the upper surface get converted into its oxide called aluminium oxide (Al2O3), which gets deposited as a thin coating on the surface of the metal. This aluminium oxide is passive which means that it is not reactive. Therefore, this metal is used for packing food articles which do not get spoiled in the foil. |

What is gypsum ? |
|
Answer» Plaster of paris Plaster of Paris, CaSO4.1/2 H2O or (CaSO4)2.H2OIt occurs in nature as gypsum and the anhydrous salt as anhydride. It is prepared by precipitating a solution of calcium chloride or nitrate with dilute sulphuric acid.On heating the monoclinic gypsum is first converted into orthorhombic form without loss of water. When the temperature reaches 120°C, the hemihydrates or plaster of Paris is the product. The latter losses water, becomes anhydrous above 200°C and finally above 400°C, it decomposes into calcium oxide. |

How do cardohydrate protin and fat get digested in human being |
| Answer» Digestion of carbohydrates: Starch is digested in the mouth by salivary amylase. Other forms of carbohydrates are digested in the small intestine.Starch + Salivary Amylase → SucroseMaltose + Maltase → GlucoseLactose + Lactase → Glucose + GalactoseDigestion of Proteins: Partial digestion of protein takes place in the stomach by gastric enzyme pepsin. Further digestion of protein happens in the small intestine.Protein + Pepsin → Peptone + Proteose(Protein + Peptone + Proteose) + (trypsin + chymotrypsin) → DipeptidesDigestion of Fat: Fat is at first emulsified by bile and then its digestion happens in the small intestine.Fat + Lipase → Fatty acids + Glycerol | |

Explain series combination or parrallel combination |
|
Answer» Resistors in Series : A circuit is said to be connected in series when the same amount of current flows through the resistors. In such circuits, the voltage across each resistor is different. In a series connection, if any resistor is broken or a fault occurs, then the entire circuit is turned off. The construction of a series circuit is simpler compared to a parallel circuit.The total resistance of the system is given by the following relation.Rtotal = R1 + R2 + ….. + RnResistors in Parallel: A circuit is said to be connected in parallel when the voltage is same across the resistors. In such circuits, the current is branched out and recombines when branches meet at a common point. A resistor or any other component can be connected or disconnected easily without affecting other elements in a parallel circuit.The total resistance here is given by the following relation. when resistor is connected in series manner in a circuit is called series combinationwhen resistor is connected in parrallel manner in a circuit is called parrallel combination |

5 point on angiosperms |
| Answer» Angiosperms represent the most advanced group of plants and have been of immense importance to humans, more than any other group. They are able to grow in a variety of habitats . They can grow as trees, shrubs, bushes, herbs and small flowering plants.\tThey all have flowers at some stage in their life. The flowers are the reproductive organs for the plant, providing them a means of exchanging genetic information.\tThey have small pollen grains that spread genetic information from flower to flower. These grains are much smaller than the gametophytes or reproductive cells used by non-flowering plants.\tSince the size is small it makes the process of fertilization occur quicker in the flowers of angiosperms and makes them more efficient at reproducing. Also they have much smaller female reproductive parts than non-flowering plants, allowing them to produce seeds more quickly.\tAll angiosperms have stamens. Stamens are the reproductive structures found in flowers that produce the pollen grains that carry male genetic information.\tThey have carpel that encloses developing seeds that may turn into a fruit.\tA great advantage for angiosperms is the production of endosperm. Endosperm is a material that forms after fertilization and serves as a highly nutritional food source for the developing seed and seedling.\xa0 | |

Why force is not exert when we placed current carrying in parallel with magnetic field |
|
Answer» Shukriya Magnetic force on a current-carrying conductor in a magnetic field can be expressed as the followingF=Bil Sin θWhere F is force acting on a current carrying conductor,B is magnetic flux density (magnetic field strength),I is magnitude of current flowing through the conductor,\xa0l\xa0is length of conductor andθ\xa0is angle that conductor makes with the magnetic field.When the conductor is perpendicular to the magnetic field, the force will be maximum. When it is parallel to the magnetic field, the force will be zero.\xa0The Factors affecting the force experienced by a current carrying conductor placed in a uniform magnetic are:B is magnetic flux density (magnetic field strength),I is magnitude of current flowing through the conductor,\xa0l\xa0is length of conductor andθ\xa0is angle that conductor makes with the magnetic field. |

Explain magnetism in human body? |
| Answer» Whenever there is an electric current, there is a magnetic field. Even the extremely weak ion currents that travel along the nerve cells in our body produce magnetic fields. When we try to touch something, our nerves carry an electric impulse to the muscles we need to use. This impulse creates a temporary magnetic field. These fields are about one billionth as weak as the Earth’s field. Two main organs in the human body where the magnetic field produced is significant are heart and brain. | |

What are the ph papers colours and we can know that it is acidic or basic |
| Answer» The acidic solution has value of hydrogen ion concentration less than 7 on pH scale. The basic solution has value of hydrogen ion concentration greater than 7 on pH scale. pH indicator is a chemical that turns different colours in different media. For example, blue litmus turns red in acidic medium, the red litmus turns blue in alkaline medium. | |
