Difference between Permanent magnet and temporary magnet |
| Answer» \tPermanent magnets have the magnetic properties even if the external field is zero. Temporary magnets have magnetic properties only in the presence of an external magnetic field.\tPermanent magnetism is seen on hard magnetic materials, which fall in to the ferromagnetic material family. Temporary magnetism is seen in soft magnetic materials, paramagnetic materials and diamagnetic materials.\tPermanent magnets are used in devices such as electric motors and generators. Temporary magnets are used in places such as cranes. | |

How do i read and learn physics?? Will you guys please can give me suggestions?? |
|
Answer» When u learn physics always think like a scientist and go deep to every point Try to read first of all the NCERT Science Textbook. Concepts are very necessary for physics hence the textbook will surely help you. Then comes the numericals. For the chapters such as Electricity, Magnetic Effects of Electric Current and Ray Optics it\'s quite important to solve the numericals. First of all solve the basic level of numericals and then when you are perfect in solving them, try to solve the numericals of \'HC Verma Concepts Of Physics\' TEXTBOOK....?I hope u liked it..... Bro try to solve problems and ask doubts to ur teacher Do the revision daily of one one topic Hahaha lol..... You don\'t know to read physics |

Working of A.C. and D.C. generator |
| Answer» Working of Ac generator:\tThe axle is rotated such that it moves in the clockwise directions that is AB moves up and CD moves down.\tAccording to Fleming\'s Right Hand rule, the induced current is setup in the coil along B1-> AB -> BC -> CD -> B2. This means that the external current flows from B2 to B1.\tAfter half a rotation, arm CD starts moves up and AB moves down.\tAccording to Fleming\'s Right Hand rule, the induced current is setup in the coil along B2-> AB -> BC -> CD -> B1. This means that the external current flows from B1 to B2.\tThus after every half rotation of the coil, the current changes direction. This is called an AC current.\tAC current(Alternating current) : Changes its direction after equal intervals of time. It is easier to transmit this current over long distances due to lesser loses and hence this is the current that is supplied to our houses from the electricity department.\t | |

|
Answer» The relationship between the plant kindom and the animal kingdom is called ecosystem Ecosystem is defined as the structural, functional and self-sustaining unit of biosphere, which consists of biotic and abiotic components.Biotic components of ecosystem Producers are the green plants which can prepare food themselves. Green plants can prepare their own food due to the presence of chlorophyll. For e.g.: Sunflower, mango plant.Consumers are the heterotrophs that depend on green plants directly or indirectly for their food. For e.g.: Dog, Lion etc.Decomposers are the saprophytic organisms that feed on dead and decaying organic matters and decompose them into simpler forms. For eg: Bacteria, Fungi etcTypes of ecosystemThere are two types of ecosystemAquatic ecosystem (pond ecosystem)Terrestrial ecosystem (grassland ecosystem) |

Why hydrogen gas is not evolved when a metal react with nitric acid |
|
Answer» When metals react with dilute nitric acid, hydrogen gas is not evolved because nitric acid is a strong oxidising agent. As soon as hydrogen gas is evolved, the nitric acid oxidises it to water and the acid gets reduced to nitrogen oxides. So, metals reacting with nitric acid tend to give oxides of nitrogen rather than hydrogen. But, magnesium and manganese react with nitric acid to give hydrogen gas. Nitric acid is very reactive and itself changes into nitrogen oxide |
