Can we say that a charged object attracts an uncharged object by first chargingit through induction? Explain your answer. |
| Answer» <p>Yes we can. Actually a charged object always attracts an object which is opposite in charge.</p><p>But if the other object is neutral in nature then the charged object would not be able to attract it.</p><p>So first of all the if an object is positvely charged on all sides of its dimensions then if it is brought near to one side of the uncharged object that side of the uncharged object facing the charged object gets the opposite charges(negative). And the other side which is facing away from the charged object is carrying positve charge.</p><p>So a charged object tries to attract an object by imparting negative charges to one side of the uncharged object and that process of imparting negative charge is calledinduction.</p><p>Another method for imparting opposite charges to an uncharged object would be byconduction,but in that case both( charged and uncharged) should be brought in contact with each other so that the charged body could share the charges with the other and thus imparting a negative charge at the other side of the body. And resulting in repulsion due to like charges of the bodies.</p> <p>what is nutrition </p> <p>For induction process, while the net charge on both sphere is constant, but due to different configuration of arrangement of charges on both sphere due to induction process, there is net force between them </p> | |

explain the working of automatic fire alarm |
| Answer» <p>There are two types of smoke detectors. These are the optical detector and the ionization detector. The optical smoke detector detects smoke by using light sensors (infrared LED). When smoke particles pass through the chamber of the optical detector, it scatters light that triggers the alarm. In the ionization detector, if the smoke particle enters the chamber of the ionization detector it will reduce air ionization inside the chamber of the ionization detector and triggers the alarm.</p> <p>given a simple logic it is good but so long and hard to learn and it is for the big std not for small std</p> <p>wait we will provide you in simple way after editing it.</p> <p>OK</p> <p>In fire alarm there is a wire of low melting point which melts in heat. Then in response a gong attached to it with a mechanism of electronic bell rang. In mechanical fire alarm system, when the hook pilled there is a liver which pushes down and allow the bell to ring.</p> | |

explain the function of automatic fire alarm with the help of a labelled diagram. |
| Answer» <p>Principle of OperationThe primary purpose of a fire indicator panel is to monitor each circuit, zone or point for any condition (alarm signal or other abnormal condition); display the status of that condition and to operate any required output or outputs according to the approved design of the system. These outputs are typically for the purpose of warning occupants on a fire alarm signal, notify the fire brigade, control the spread of heat, smoke or fire; or used for a wide variety of other purposes.</p><p>Before I go any further its important to define a couple of terms used in this article, to provide both context and and explanation of their meaning;</p><p>CircuitA circuit comprises an unbroken path (usually a pair of wires) along which an electric current exists or is intended or able to flow. In fire alarm terms this generally means the wiring connecting one or more detectors to the fire panel.</p><p>Zone</p><p>A zone is a group of one or more detectors, grouped by their common location or in the case of a collective circuit all of the detectors on that circuit. Another way to describe a zone is one of the following;one or more detectors on an single collective circuit or;one or more detectors, in a common location, defined in software on an addressable circuit.Standards also limit the number of detectors a zone may comprise.</p> <p>send phone no. </p> | |

I glowing a crop.I LUVULTA2. How do animals and human beings help in the dispersal of seeds?Think And Answer:E |
| Answer» <p>a)Yes humans helps in dispersal. Humans eat various fruits and vegetables and throw their seeds after eating. These seeds when get adequate condition for germination, grows to become plants. In this way humans help in seed dispersal.</p><p>b) Animals eats seeds along with fruits. The seeds they eat are not digested at all. The seeds come out in the form of faeces(water material of the body). Since animals move from one place to another, the seeds in their stomach also goes. When they excrete, the seeds come out and thus they are dispersed from the original place.</p> <p>as when they Move; the pollengrains move with them and fall on certain place</p> <p>Animal dispersal:There are of multiple ways animals can aid in seed dispersal. Seeds can pass through the digestive tracts of animals, be transported in mud attached to hooves and hide, and sprout from seed caches. Knapweeds seeds and seedheads cling to fur like burrs. The sharp thorns on yellow starthistle seedheads can jab into passing animal hide. Small barbs on cheatgrass and medusahead seeds facilitate being picked up by feathers and fur.</p><p>Human Dispersal:Human play a big part in seeds dispersal today. Seeds stick into socks, shoes, and other clothing. Vehicles and farm machinery can get seeds and plant parts caught underneath. Transported soil, animal feed, and seed can contain weed propagules. We are particularly adept at weed dispersal because we travel both frequently and over long distances.</p> <p>as when they moved,the pollenhrains move with them and fall o certain place</p> | |

Q2.How do leaves of boat plants and assout source of food? Guve sustelesuitable exemple |
| Answer» <p>Green plants make their food themselves. Green leaves make food from Carbon dioxide and water in the presence of sunlight and chlorophyll.</p><p>Leaves have several tiny pore-like structures on the lower surface. Such a pore is called stomata through which leaves absorb carbon dioxide from air. Water is transported to the leaves through hair like pipelines from the roots. These pipelines are present throughout the plant, i.e. from roots to branches and leaves. These pipe-lines are known as Xylem. Xylem is a type of tissue. Chlorophyll, a green pigment, is found in green leaves. Chlorophyll absorbs sunlight and gives energy. Chloroplast is the site of photosynthesis. Carbohydrate is used as food and oxygen is emitted out to atmosphere. This whole process of making food by plants is called photosynthesis.</p> | |

19. What is chloroplast and define its work |
| Answer» <p>Chloroplasts are the food producers of the cell. The organelles are only found inplantcells and some protistssuch as algae. Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast.</p> <p>it traps light energy from sun helpful in making the food for plants</p> | |

EXPLAIN HOW ECOSYSTEM IN A FOREST IS MAINTAINED. |
| Answer» <p>Ecosystems are collections of large numbers of interconnected species, each of which has different needs. This broad diversity of needs ensures that there are enough producers, consumers and decomposers to keep the habitat functioning as it should. As small disturbances occur to the habitat, the relative number of individuals and species varies. Over time, these disturbances tend to disappear, returning the conditions to normal. When this occurs, the number of individuals and species returns to normal.</p><p>For example, if too many oak trees die in a forest, the number of squirrels living in the forest decreases. This means that there are fewer predators eating acorns, and so, after 20 or 30 years, the number of oak trees returns to its previous levels. Now, with more acorns present, the squirrel population rebounds as well.</p><p>While ecosystems often last a long time in the natural world, most evolve just as species do. In some areas, this process takes thousands of years, while other ecosystems may evolve and change over the course of a few years.</p> | |

Light, Shadows andReflections |
| Answer» <p>Light: Light is a form of energy which helps us in seeing objects. When light falls on an object, some of the light gets reflected. The reflected light comes to our eyes and we are able to see an object.Shadow: Shadow is space when the light is blocked by an opaque object. It is just that part where light does not reach. When you stand in the sun, you are able to see your shadow behind you.Reflection:Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water wave</p> | |

Q.9.State any two uses of x-rays.(OR) |
| Answer» <p>answer</p> <p>The most common form of X-ray used is X-ray radiography, which can be used to help detect or diagnose:</p><p>1.Bone fractures</p><p>2.Infections (such aspneumonia)</p><p>3.Dental issue</p> <p>The main use of X-rays is in medicine. A comman application is in the form of X-ray machines, which take photos of a patient’s body. If an arm or leg were broken for example, then this limb would be put in front of the X-ray with a piece of photographic film behind. The X –ray is turned on briefly and goes through to the film. The rays go through the skin and flesh easily, showing up as dark areas on the film, but with more difficulty through bone. They are slowed down and so these areas are much lighter. X-rays can also be used to kill cancer cells, but also kill healthy cells, so must be used with much care.</p><p>Other uses are in industry, at airports to check customers and baggage and by art historians to see if a picture has been painted on top of an older one. X-ray diffraction is also very important in spectroscopy and as a basis for X-ray crystallography. The diffraction of X-rays by a crystal where the wavelength of X-rays is comparable in size to the distances between atoms in most crystals is used to disperse X-rays in a spectrometer and to determine the structure of crystals or molecules.</p> <p>shalini is too shy speak with stranger</p> | |
