Image formation by spherical mirror and their conclusion |
| Answer» Spherical mirrors are of two types:\tConvex mirrors or diverging mirrors in which the reflecting surface is curved outwards.\tConcave mirrors or converging mirrors in which the reflecting surface is curved inwards. Some terms related to spherical mirrors:1. The centre of curvature (C) of a spherical mirror is the centre of the hollow sphere of glass, of which the spherical mirror is a part.\tThe radius of curvature (R) of a spherical mirror is the radius of the hollow sphere of glass, of which the spherical mirror is a part.\tThe pole (P) of a spherical mirror is the centre of the mirror.\tThe principal axis of a spherical mirror is a straight line passing through the centre of curvature C and pole P of the spherical mirror.\tThe principal focus (F) of a concave mirror is a point on the principal axis at which the rays of light incident on the mirror, in a direction parallel to the principal axis, actually meet after reflection from the mirror.\tThe principal focus (F) of a convex mirror is a point on the principal axis from which the rays of light incident on the mirror, in a direction parallel to the principal axis, appear to diverge after reflection from the mirror.\tThe focal length (f) of a mirror is the distance between its pole (P) and principal focus (F).\t\tFor spherical mirrors of small aperture, R = 2f.\tImage formation by Spherical Mirrors:The nature, position and size of the image formed by a concave mirror depends on the position of the object in relation to points P, F and C. The image formed is real for some positions of the object. It is found to be a virtual image for a certain other position. The image is either magnified, reduced or has the same size, depending on the position of the object.\t | |

Why inhalation is called active process and exhalation is called passive process??? |
| Answer» Inhalation\xa0is an\xa0active process\xa0because it requires energy and work. Expiration is typically a passive process that happens from the relaxation of the diaphragm muscle (that contracted during inspiration). The primary reason that expiration is passive is due to the elastic recoil of the lungs.\xa0Exhalation begins when inhalation ends.\xa0The process of\xa0inhalation\xa0occurs due to an increase in the lung volume (diaphragm contraction and chest wall expansion) which results in a decrease in lung pressure in comparison to the atmosphere; thus, air rushes in the airway. There is no contraction of muscles during\xa0exhalation; it is considered a\xa0passive\xa0process. | |

Describe long form of periodic table? |
| Answer» The modern or\xa0long form\xa0of the\xa0periodic table\xa0is based on the modern\xa0periodic\xa0law. The\xa0table\xa0is the arrangement of elements in increasing order of their atomic numbers. The modern\xa0periodic table\xa0is the present\xa0form\xa0of the\xa0periodic table. And it consists of 18 vertical columns and 7 horizontal rows.Main features of long form of periodic table:\tGroups. The vertical columns in the periodic table are known as groups. ...\tPeriods. There are 7 periods in the long form of periodic table. ...\tLanthanoids. Group of 14 elements in the sixth period. ...\tActinides. Group of 14 elements in the seventh period after actinium. | |

Anyone know about impulse? ? |
|
Answer» A sudden strong wish to do something.. a sudden desire to do something without thinking about the results Less * amount A sudden effect which having a great amount of electrical energy applying on our veins and machine wire it is called Impulse. Impulse\xa0is a vector, so a negative\xa0impulse\xa0means the net force is in the negative direction.\xa0Air bags in cars are designed with\xa0impulse, or momentum change principles. When a driver gets into an accident their momentum carries them forward into the steering wheel. By putting an airbag in the car, a smaller force is exerted over a longer period of time to change the momentum of the driver to a stop. |

How do we study the color of flame in Bunsen burner by regulating the flow of air ?????????? |
| Answer» A Bunsen burner flame produces energy from burning gas. If the air hole is open the flame burns in plenty of oxygen. Combustion is complete and a\xa0blue flame\xa0is seen.\xa0Increasing the\xa0amount of fuel gas\xa0flow through the tube by opening the needle valve will increase the size of the\xa0flame. However, unless the airflow is adjusted as well, the\xa0flame\xa0temperature will decrease because an increased\xa0amount of gas\xa0is now mixed with the same\xa0amount\xa0of\xa0air, starving the\xa0flame\xa0of oxygen. | |

Why does a compass needle gets deflected when brought near a bar magnet❓❓☺️☺️ |
|
Answer» Thank you raman...... It\'s my pleasure ( yes , i am sad ) Compass needle get deflected when brought near a bar magnet because compass neddle is made up of a magnet. As we know magnet follow property of repulsion that is why compass needle gets deflected. Thanks neha....(what happened neha i think you are sad)? The needle of a compass is a small magnet. That\'s why when a compass needle is brought near a bar magnet, its magnetic field lines interact with that of the bar magnet. Hence, a compass needle gets deflected. |

How can the direction of magnetic field lines at a place be determine❓☺️☺️ |
|
Answer» Hi ishika ❤️? Thank you** Thanks you both of you........(hi avi...)☺️ The direction of magnetic field lines at a place can be determined by using a compass needle. A compass needle placed near a magnet gets deflected due to the magnetic force exerted by the magnet. The north end of the needle of the compass indicates the direction of magnetic field at the point where it is placed ?❤️☺️☺️ The direction of a magnetic field at a point is determined by placing a small compass needle. The N - pole of compass indicates the direction of magnetic field at that point. |

Difference between motion and inertia. |
|
Answer» Inertia is that property of a body which can restist is the state of motion \tINERTIA OF MOTIONINERTIA OF REST(1) The inherent property of a body by virtue of which it cannot change its state of motion, is called inertia of motion . (2)It is due to inertia of motion that a rotating fan continues to rotate for some time even after it is switched off or a person falls when he jumps from a moving bus.(1) The inherent property of a body by virtue of which it cannot change its position of rest, is called inertia of rest . (2) It is due to inertia of rest that passengers in a vehicle get a backward jerk when the vehicle starts suddenly or fruits hanging from a branch fall down when the branch is shaken\t Thanks We say any object in motion it takes change their place with respect to time. But inertia haiving opposite to them it whould be cal. By formula . |

Define inertia? |
|
Answer» Intertia is that property whis can restist in the state if motion. An object cannot change its state of rest or state of uniform motion in a straight line by itself. In other words, all objects resist a change in their state of rest or motion.This tendency of objects to resist or oppose change in their state of rest or motion is called inertia.Mass of an object is the measure of its inertia. Most wlcm....... Thanks Inertia is the tendency of an object to oppose change in its state of rest or motion. |

Differentiate between photosynthesis and respiration |
|
Answer» \thotosynthesisRespirationIt takes place only in the presence of sunlight.It continues throughout day and night, in sun and darkness.It occurs only in the green cells of the plant.It occurs in all the cells of an organism.It is an endothermic reaction as it absorbs sunlight.It is an exothermic reaction, as it gives out energy.It utilises carbon dioxide and water.It evolves carbon dioxide and water.It builds up complex compounds such as carbohydrates from simple inorganic compounds. So, it is an anabolic process.It breaks complex substances into simple substances. So, it is a catbolic process.It converts light energy into chemical energy.It releases potential or chemical energy which is used variously in the body.Carbon dioxide and water are raw materials for photosynthesis.Sugars and oxygen are raw materials for respiration.It produces ATP by harvesting light energy.It forms ATP from energy liberated during oxidation of food.Hydrogen of water is used in the synthesis of NADPH.Hydrogen of food is used in the formation of NADP, NADPH and\xa0FADH2\u200b.ATP and NADPH are used in the synthesis of organic compounds.ATP and reduced coenzymes are made available to cells for various metabolic activities.\t Respiration is a catabolic reaction while photosynthesis is an anabolic reaction. Both are vice versa to each other |

why does distilled water not conduct electricity , whereas rain water does |
| Answer» The availability of ions is very important to conduct electricity. Distilled water is a pure type of water which does not contain any ions in it. Whereas rainwater contains dissolved gasses such as SO2, CO2. These gases dissolve in water to form some kind of acids like carbonic acids which dissociates to give ions. Thus rainwater is conducting electricity while distilled water is not conducting electricity. | |
