R.H.T rules |
| Answer» Fleming\'s right-hand rule (for generators) shows the direction of induced current when a conductor moves in a magnetic field. It can be used to determine the direction of current in a generator\'s windings.When a conductor such as a wire attached to a circuit moves through a magnetic field, an electric current is induced in the wire due to Faraday\'s law of induction. The current in the wire can have two possible directions. Fleming\'s right-hand rule gives which direction the current flowsThe right hand is held with the thumb, first finger and second finger mutually perpendicular to each other (at right angles).· The thumb is pointed in the direction of motion of the conductor.· The first finger is pointed in the direction of the magnetic field. (north to south)· Then the second finger represents the direction of the induced or generated current (the direction of the induced current will be the direction of conventional current; from positive to negative) | |

How fossil is formed? |
| Answer» Fossils are formed in the following way:Usually, when the organisms die, their bodies decompose and be lost. But sometimes the body or at least some parts may be trapped in an environment that does not let it decompose completely and eventually harden and retain the impression of the body parts. All such preserved traces of living organisms form fossils.The age of the fossil can be determined:i. By determining the layer in which the fossil is found. The deeper the layer the older the fossil.\xa0ii. Other method to determine the age of Radio-carbon dating. | |

Classifications and evolution are interlinked |
|
Answer» Organisms differ in their form, structure and mode of living. Hence, based on their similarities they should be grouped. The grouping of related organisms helps us in studying their evolutionary relationships. Classification is the division of organisms on the basis of characteristics into groups and sub-groups. A characteristic may be a particular form or function.For example, classification of animals can be done based on some criteria.Criteria for classification:\xa0Animals are classified on the basis of different features.*Cellular or tissue level of body organisation.*Body symmetry.*Type of body cavity called as coelom.*Presence or absence of segmentation.*Presence or absence of a backbone.Evolution:\xa0It is the sequence of gradual changes over millions of years in which new species are produced. Classification of species is done by knowing the characteristics which evolved over a long period of time. Evolution are the slow nd gradual changes which lead to the formation of new species. To study it more conveniently v classify the species on different basis.. So as to know more about their origin becomes easy.. |

Electrolytic refining ??? |
|
Answer» In an appratus impure metal is made as anode And the pure metal of thin strip made the cathode when we start passing current through appratus the pure metal from anode goes into the solution (the solution Is made up of the salt of impure metal for eg CuSo4) slowly and steadily the metal stick on pure strip and the impure thing from anode goes into electrolyte the slouble thunder dissolve in solution while the insoluble metal settles down. Known as anode mud In this a metal is refined from its ore by taking impure metal as anode and a peice of pure metal as cathode Nd then putting this circuit in the solution of same metal. Thus it is refined from its ore and gets collected in the piece of metal on the cathode Electrolytic refining is the process of refining impure metals by using electricity.In this process , impure metal is made anode and a strip of pure metal is made cathode.A solution of a soluble salt of the same metal is taken as the electrolyte. |

Explain corrosion |
| Answer» Rusting is known as corrosion , when a metal comes in contact with moisture and air present in atmosphere gains a coating on iron called rust, like brown coating on iron and black coating on silver , green coating on copper.it is because metals react with sulpher present in air and forms a sulphide coating. Like silver sulphide, iron sulphide etc. | |

What are the merits and demerits of mendeleev\'s periodic table ?? |
|
Answer» Merits are as follows:-\xa01. There was a regular gradation in physical and chemical properties of elements.\xa02. The group number of an element indicates highest oxidation state that it can attain.\xa03. There were many vacant spaces in Mendeleev\'s periodic table for the elements to be discovered. He named them Eka-Boron, Eka-Aluminium and Eka-silicone He also predicted the properties of these undiscovered elements including atomic masses. These elements were discovered as Sc ,Ga and Ge with\xa0same features as he predicted.\xa04. Mendeleev’s arrangement helped to correct atomic masses of a number of elements.Demerits are as follows:-\xa01. The elements, if arranged according to their atomic weights show an evident periodicity of properties.\xa0\xa02. Elements which are similar as regards their chemical properties have atomic weights which are either nearly the same value or which increase regularly.\xa0\xa03. The arrangement of the elements or of groups of elements in the order of their atomic weights, corresponds with their so called valencies.\xa0 Ans is i don\'t know |

Differences between mendeleev\'s periodic table and modern periodic table |
| Answer» Mendeleev was not able to explain:-1) the position of isotopes. 2) in his table sometime element with similar Property are far while element with different property are near. 3) sometime element with greater weight come first than element with less weight. But modern periodic table remove all these problems. | |
