Energy conservation in hydro power plant |
|
Answer» The power station where electricity is produced by using the energy of flowing water to drive generators is called hydro power plant or hydroelectric power station.The energy conservation that take place in hydro power plant are as follows:1.The water is collected in a large reservoir or manmade Lake behind the dam. In this process the kinetic energy of flowing water gets transformed into potential energy of water stored behind the dam.2. The water falls from a high level of the dam it flows at a very high speed. The potential energy of water gets converted into kinetic energy.3. The kinetic energy of flowing water rotates the Blades of the turbine. Here the kinetic energy of flowing water is converted into mechanical energy of the turbine.4. The moving armature of the generator in the magnetic field generate electricity. Here the mechanical energy of the turbine is converted into electrical energy in the generator.Read more on Brainly.in - https://brainly.in/question/2962233#readmore ?????

Plz tell me how fossils help in tracing the process of organic evolution ? |
|
Answer» The fossils provide evidence of evolution. For example, a fossil bird called Archaeopteryx looks like a bird but it has many features which are found in reptiles. This is because Archaeopteryx has feathered wings like those of birds but teeth and tail like those of reptiles. Therefore, Archaeopteryx is a connecting link between the reptiles and birds and suggests that birds have evolved from reptiles. Thus, fossils provide evidence that the present plants and animals have originated from the previously existing ones through the process of continuous evolution. Thnx Because organic evolution includes living organism They give clues that the present-day organisms are originated from the ancestors through the process of evolution. Because the characters inherited from the parents to the offspring remain the same |

List two differences between acquired and inherited traits |
|
Answer» Acquired Traits Inherited Traits1. These are somatic variations.These are genetic variations.2. Acquired traits develop due to the effects of environmental factors, use and disuse of organs and special (conscious) efforts.Inherited traits develop due to reshuffling of genetic material and mutations.3. These traits develop throughout the lifetime of an individual, and die with the death of that individual.These traits are transferred (inherited) by the parents to their offspring. They do not die and are passed on to the next generation.4. Example-Learning of dance, music, etc., and muscular body of a wrestler.Example — Attached or free earlobe and curly hair. Acquired trait:in which the organism develope itself from the enviroment like cycling , runing , boxing , driving etc.Inherited traits:the trait in which charcterstics of parents passing throw by genes like ear lobe , hair colour , eye colour ,and body colour etc i hope this help you all the best for sci exam |

Three differences between the process of galvanisation and alloying? |
| Answer» \tGalvanisation is a method of protecting steel and iron from rusting by coating them with a thin layer of zinc. \tAlloying: An alloy is a homogeneous mixture of two or more metals or a metal and a non-metal in a definite proportion. The resultant metals, called alloys do not corrode easily.For example: Brass (copper and zinc), Bronze (copper and tin) and stainless steel (iron, nickel, chromium and carbon). | |

Answer» Pta nhi mai to gussa nhi hu us se sowndu smarkee kha h Yhi hu bolo Hii kaha gaya thu Frustum of a cone:Cut a right circular cone with a plane parallel to the base of the cone, then the solid shape between the plane and the base of the cone is called the frustum of a cone.e.g. Flower pots have a shape as the frustum of a cone.The surface area and the volume of the frustum of a cone can be calculated using standard formulae.CSA of the frustum of a cone =\xa0πl( r1\xa0+ r2).where r1\xa0= radius of the larger circular face of the frustum, r2\xa0= radius of the smaller circular face of the frustum, and l = slant height of the frustum.l =\xa0h2+(r1-r2)2h2+(r1-r2)2 and h is the height of the frustum.TSA of a frustum of a cone = πl(r1\xa0+ r2) + πr12\xa0+ πr22Volume of the frustum of a cone = (1/3) πh (r12\xa0+ r22\xa0+ r1\xa0r2) Hi |

List 3 character feature of electric current |
| Answer» \tWe know that electric current is the result of the flow of electrons. The work done in moving the electron stream is known as electrical energy. The electrical energy can be converted into other forms of energy such as heat energy, light energy, etc. For example, in an iron box, electric energy is converted to heat energy. Likewise, the electric energy in a bulb is converted into light energy.\tThere are two types of electric current known as alternating current (AC) and direct current (DC). The direct current can flow only in one direction, whereas the alternating direction flows in two directions. Direct current is seldom used as a primary energy source in industries. It mostly used in low voltage applications such as charging batteries, aircraft applications, etc. Alternating current is used to operate appliances for both household and industrial and commercial use.\tThe electric current is measured in ampere. One ampere of current represents one coulomb of electric charge moving past a specific point in one second.\t1 ampere = 1 coulomb / 1 second\tThe conventional direction of an electric current is the direction in which a positive charge would move. Henceforth, the current flowing in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. | |

Uniform and nonuniform composition |
| Answer» The difference between uniform and non-uniform mixtures is the degree at which the materials are mixed and the sameness of their composition throughout the mixture.Another word for a uniform mixture is a homogeneous mixture. Homogeneous mixtures have the same composition throughout (home = the same). There is only one phase (state of matter) observed in a uniform, homogeneous mixture. By definition, solutions are uniform/homogeneous mixtures. Examples would be Kool-Aid, fruit punch, salt water, vinegar, vodka, etc.On the other hand, non-uniform mixtures are also called heterogeneous mixtures. Heterogeneous mixtures are not the same throughout (hetero = different). Trail mixes and salads are great examples of non-uniform, heterogeneous mixtures. Every handful that is grabbed or bite that is taken is slightly different. | |
