Draw a labelled diagram to explain the formation of rainbow in the sky . Class 10 |
|
Answer» When a beam of white light enters a prism, it gets refracted and splits into its seven constituent colours. This splitting of the light ray occurs because of the different angles of bending for each colour. Hence, each colour while passing through the prism bends at different angles with respect to the incident beam. This gives rise to the formation of the colour spectrum. Rainbow is formed after three phases first internal reflec5ion refraction dispersion Rainbow is formed by water droplet . |

Why safranin is used in staining sections of plants? |
|
Answer» safranin is used as a counterstain in some staning protocols,colouring all cell nucli red. Safranin is a dye which can be taken up by a cell and it gives a pink colour. The cell as well as the background is transparent and it is difficult to visualise the cells as such. Staining imparts colour the cell or its components and enhances its contrast and makes it easier to see the structure of the cells. |

Golden rule of chemistry |
|
Answer» 6. Steric interactions (atoms bumping into each other) can prevent reactions by keeping the reactive atoms away from each other.7. Pi electrons prefer to be delocalized over as many adjacent sp2 hybridized atoms (or sp1 hybridized atoms in some cases) as possible, and aromaticity is the most stable form of pi electron delocalization. Pi electrons cannot delocalize onto or through sp3 hybridized atoms since an sp3 atom has no 2p orbital available 7 Golden Rules will allow you to develop an intuitive feel for organic chemistry, and things will make sense! (Warning: this means you will start thinking like a chemist, but, of course, no one needs to know if you don\'t want them to know.)1. Atoms prefer filled valence shells. This rule explains why atoms make bonds, and the type of bonds created. A corollary is that centers of electron density (bonds and lone pairs of electrons) repel each other so they stay as far apart as possible. This latter rule, the basis for the so-called VSEPR model, explains 3-dimensional molecular structure.2. The most important question in chemistry is "Where are the electrons?" The answer is that electrons are generally in higher amounts around the more electronegative atoms (e.g. F, Cl, O, N). The electronegative atoms pull electron density away from the less electronegative atoms (e.g. C, H) to which they are bonded. Thus, understanding electronegativities provides a simple method of deciding which portions of a molecule have a relatively high electron density, and which portions have a relatively low electron density.3. Nature hates unpaired electrons. If a molecule must have an unpaired electron (a.k.a. radical), it is better to have the unpaired electron distributed over as many atoms as possible through resonance, inductive effects, and hyperconjugation.4. Nature hates localized charges. If a molecule must have a charge, it is better to have the charge distributed over as many atoms as possible through resonance, inductive effects, and hyperconjugation. In addition, when given the choice, it is better to have more negative charge on a more electronegative atom (e.g. O), and more positive charge on a less electronegative atom (e.g. C).5. Most reactions involve nucleophiles (molecules with a location of particularly high electron density) attacking electrophiles (molecules with a location of particularly low electron density). When in doubt, transfer a proton! Thus, simply understanding where electrons are provides you with the best way of analyzing new molecules so that you will be able to PREDICT how they will react. |

Why is red coloured light is used in traffic signals to indicate vehicles to stop? Explain |
|
Answer» becouse lemda red is greater than lamda blue. Beacuse red colour light has high wavelength so it can not be scaterd in atmospheric presure Red coloured lights is used in traffic signals because it has more frequency than other colours Because Red light has high wavelength and it can be seen from far distances....... Cause it is least scatttered and can be seen from far distance easily Bcaus RED light has least deviation property. |

What is Ohm\'s law? Derive an equation for Ohm\'s law? |
|
Answer» At a constant temperature ,the current passed through a wire id directly proportional to potential difference. When a I current is flowing through a semiconducter across its terminals of different potential difference V at constant heat.Then current I is directly proportional to V. V is proportinal to I Where sign of proportionality replaced by RSo, V = IR |

What is law of :- (1.)Segregation, (2.) Independent assorment and (3.) Dominace |
|
Answer» 1) The principles that govern heredity were discovered by a monk named Gregor Mendel in the 1860s. One of these principles, now called Mendel\'s Law of Segregation, states that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization. 2) Mendel\'s Law of Dominance can also be simply stated as: “In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype.”3) Mendel\'s law of independent assortment states that the alleles of two (or more) different genes get sorted into gametes independently of one another. In other words, the allele a gamete receives for one gene does not influence the allele received for another gene. Law of dominance:the gene factor always work in pair . They together control a trait. The dominant gene always shows its effect irrespective of the other gene. |

What are binary fission and multiple fission |
|
Answer» Binary fission is a type of asexual reproduction in which parent cell spilts into two daughter cells. Amoeba reproduces by this method of asexual reproduction,this is a binary fission.whereas, In multiple fission many daughter cells are produced from a single parent cell. For example- plasmodium this is known as a multiple fission. The asexual reproduction in which organisms are divided into two new organisms are called binary fission.ex Amoeba.The asexual reproduction in which organisms are divided into two or more organisms are called multiple fission.ex malarial parasites. |

What is mean by soil profile |
|
Answer» A soil profile is a vertical section through different layers of soil. Each layer has different texture, colour and chemical composition. These layers are termed horizons. The soil consists of three horizons: Horizon A, Horizon B and Horizon C. A soil profile is define as a vertical section of the soil that is expond by a soil pit. A soil pit is a hole that is dug from the surface of the soil to under laying bedrock. Hii sachin hi guys?? |

Please help me to understand the concept of electrical motor and generator |
|
Answer» yes Anushka and isha both are ryt. Electric motor consists of 1. Armateur- Rectangular coil ABCD insulated of copper wire. 2.Commutator- They r actually 2 split rings P&Q3. 2 brushes- Made up of carbon or metal X&Y4.Battery- Acts as source of energy5. Magnet- Armateur coil placed between 2 concave magnets•Principle of electric motor is to change electrical energy into mechanical energy. •When current flows into coil. From brush X&Y it flows to A to B then from C to D.This electric current produces magnetic field which is at right angle to plain of coil & also perpendicular to magnet. •The arm AB & CD experiences a force. According to Flemings left hand rule coil AB moves up & CD moves down; here couple force is produced which produces momentum. •Once the coil rotates 90 degree it becomes parallel to magnetic field thus no force act on it & it tend to stops but; due to momentum it covers another 90 degree. •Once the armateur completes 180 degree; the arms exchange their position; the current start flowing from Y in opposite direction DCBA. The device which convert electrical energy into mechanical energy is called as electric motor.The device which is converted from mechanical energy into electrical energy inthe form of alternating current is know as generator. First practise the diagram thoroughly It is very easy understand it with diagrametically |

What is the role of apprendix in our digestive system? |
|
Answer» Tq..bro ☺?? at previous time the apprendix work as a digestion of grass or unboiled food like unboiled fish and snake and other things which our grand to grands eated as a aadimanav , but now its working zero. The function of the appendix is unknown. One theory is that the appendix acts as a storehouse for good bacteria, “rebooting” the digestive system after diarrheal illnesses. Other experts believe the appendix is just a useless remnant from our evolutionary past. Surgical removal of the appendix causes no observable health problems...?? |
