Why magnesium ribbon be cleaned before the burning in air |
|
Answer» Magnesium ribbon is cleaned before burning it in air in order to remove oxide layer, presence of which slowdowns the oxidation process. So, by cleaning it, the burning process takes place easily. A magnesium ribbon is cleaned to remove the protective layer of basic magnesium carbonate from its suface so that it may readily combine with oxygen of Air on heating Magnesium ribbon is cleaned before burning .....because it forms hard layer of magnesium oxide ....which is not easy to remove that\'s why it would be cleaned before burning... if we don\'t clean it then it will not burn with dazzling flame..... |

Explain the law of independent assortment. |
|
Answer» Mendel was considered as \'Father of Genetics\' as he could explain different facts of inheritance after performing lot of experiments on pea plants. He considered genes as units of heredity. He has prosed a set of laws called as Mendelian laws. One such law is Law of independent assortment.Law of independent assortment states that when two pairs of independent alleles are brought together, they exhibit independent dominant effects. The genes of different characters are independent of one and other during gamete formation.Gene :Gene is a small point on a chromosome representing one character of an individual. Genes are units of inheritance.Alleles: These are two alternate forms of genes present on the same point on the chromosomes forming a homologous pair. Inner nhi inheritance During the inheritance two character factor segregates tontake the form of gamete which are distributed nto form in new offspring it is also known as dihybrid inner |

What is corrosion? Give any 3 example. |
|
Answer» When a metal is attacked by substances around it like moisture it is said to corrode and the process is called corrosion. Eg are reddish brown coating on iron known as rusting and green coating on copper and black coating on silver. When metals or elements are attacked by the atmospheric moisture they gets corrode and this process is known as corrosion. When metal react with air moisture gas other things in surroundings then it make its oxide it is known as corrosion. Ex rusting of iron aluminium silver etc. Corrosion: It is the process of degradation of material on continuous interaction with atmosphere. Because of Corrosion the strength of the material decreases.\xa0Ex: The materials like water pipes which are made up of metal continuously exposed to moist atmosphere will get corrode and over the time water starts leaking.\xa0The bottom layer of the boats or ships get corrode, so for every fixed period of time they will get replaced by new materials.\xa0Rusting of some of the materials in our house items |

Why sky appears blue .......please help |
|
Answer» The atoms or molecules of the gases present in the atmosphere scatter the sunlight . Wavelength of violet colour is most but our eye is more sensitive to blue colour that\'s why clear sky look blue The molecules of air and other fine particles in the atmosphere have smaller size than the wavelength of visible light. These are more effective in scattering light of shorter wavelengths at the blue end than the light of longer wavelength at the red end. Thus, the blue colour is due to the scattering of sunlight through fine particles in air. |

des describe how Ozone Layer is formed |
|
Answer» Answer:\xa0Ozone layer\xa0is naturally found in the upper part of the atmosphere called stratosphere.The atomic oxygen quickly combines with further oxygen molecules to\xa0form ozone.Ozone\xa0absorbs the potentially harmful ultra-violet radiation from the sun which can cause skin cancer and damage vegetation, among other things.Ozone gas is continuously formed by the action of UV rays on molecular oxygen.There should be a balance between production and degradation of ozone in the stratosphere. By combining of 3atoms of oxygen |

Law of flement left hand rule |
|
Answer» Stretch the thumb fore finger andmiddle finger of your left hand such that they are mutually perpendicular If force finger point in the direction of magnetic field. Middle finger in the direction of current then thumb will point on the direction of the motion of force According to Fleming’s left hand rule if we stretch the thumb, the centre finger and the middle finger of our left hand such that they are mutually perpendicular to each other. If the centre finger gives the direction of current and middle finger points in the direction of magnetic field then the thumb points towards the direction of the force or motion of the conductor. Left hand palm is stretched in such a way that fore finger,middle finger and thumb are mutually perpendicular to each other.If fore finger shows the direction of magnetic field, middle finger shows the direction of current then thumb shows the direction of force(motion). |
