What is squamus epithelium |
|
Answer» Squamous Epithelium – These are thin, flat cells that are closely packed. The squamous epithelial cells line the cavities of the mouth, oesophagus, alveoli, and blood vessels. This tissue gives protection against mechanical injury and also blocks the entry of germs. If the squamous epithelium is arranged in many layers, it is a compound squamous tissue called the stratified squamous epithelium. We find these kinds of tissues in the skin and also the lining of the oesophagus. It is the type of skin tissue which is present ob ur skin |

Define biogeochemical cycles |
| Answer» The cycling of chemicals between the biological and the geological world is called biogeochemical cycle.The biotic and abiotic components of the biosphere constantly interact through biogeochemical cycles. During these interactions, there is a transfer of nutrients between living organisms and the non-living environment.The four important biogeochemical cycles are water cycle, nitrogen cycle, carbon cycle and oxygen cycle. | |

Why black colour absorbs more heat than white colour |
| Answer» A black object absorbs all wavelengths of light and converts them into heat, so the object gets warm. A white object reflects all wavelengths of light, so the light is not converted into heat and the temperature of the object does not increase. | |

What is Composite Farming |
|
Answer» Fish culture is sometimes done in combination with a rice crop, so that fish are grown in the water in the paddy field. More intensive fish farming can be done in composite fish culture systems. In such a system, a combination of five or six fish species is used in a single fishpond. These species are selected so that they do not compete for food among them having different types of food habits.

In such a system, a combination of five or six fish species is used in a single fishpond. These species are selected so that they do not compete for food among them having different types of food habits. Composite fish culture is advantageous and economical. It yields about 8-9 times more production than monoculture. All the species of fish live in distinct zone inside the pond and have distinct feeding habits. |

Describe rutherford experiment? |
| Answer» Rutherford’s Scattering Experiment:\xa0Rutherford selected a gold foil as he wanted a very thin layer. The gold foil used by Rutherford was 0.004 millimetres in thickness. That is, the foil was about 1000 atoms thick. In his experiment, fast moving α-particles (alpha particles) were made to fall on a thin gold foil. The α-particles are helium ions with a+2 charge. Their atomic mass is 4 u. Hence, a high velocity beam of α-particles has a lot of energy. These particles were studied by means of flashes of light they produced on striking a zinc sulphide screen. The α-particles are much heavier than the sub-atomic particles present in gold atoms.\xa0Hence, he expected the α-particles to pass through the gold foil with little deflection and strike the fluorescent screen. But the observations he made were quite unexpected. | |

Why are longitudinal waves called pressure waves? |
|
Answer» because longitudinal wave are those wave in which the particles of the medium vibrate parallel to the direction of the propagation of the wave which involves a process of compression and rarefactionAs we know that in compression there is high pressure area and in refraction there is low pressure area this is the reason that the longitudinal wave are also called pressure waves Sound waves travels in the form of compressions and rarefactions,which involves change in pressure and volume of the air.thus they are called pressure waves...?? |

Give the different between atoms and molecules |
|
Answer» 1. Atoms are the smallest particles of an element whereas molecules are not the smallest part of an element.2. Atoms can not be seen even through a powerful microscope whereas molecules can be seen by a powerful microscope. 3. One atom contains the particles of only one element for eg(H) Hydrogen atom, (He) Helium atom while molecules can contain not only particles of only one element but also of more than one element for eg H2O (water) molecule, (O2) Oxygen molecule Atoms are the smallest particle of an element that can take part in a chemical reaction.

derive the eqation of law of conservation of energy |
|
Answer» Law of conservation of energy states that energy can neither be created nor it can be destroyed but it can be converted from one type to another type. Proof for Law of Conservation of Energy:Considering the potential energy at the surface of the earth to be zero. Let us see an example of a fruit falling from a tree.Consider a point A, which is at some height ‘H’ from the ground on the tree, the velocity of the fruit is zero hence potential energy is maximum there.E = mgH ———- (1)When the fruit is falling, its potential energy is decreasing and kinetic energy is increasing.At point B, which is near the bottom of the tree, the fruit is falling freely under gravity and is at a height X from the ground, and it has a speed as it reaches point B. So, at this point it will have both kinetic and potential energy.E = K.E + P.EP.E = mgX ——— (2)According to third equation of motion,v2=2g(H–X)⇒12mv2=12m.2g(H–X)⇒K.E=12m.2g(H–X)⇒K.E=mg(H–X)K.E=mg(H-X)——– (3)Using (1), (2) and (3)E = mg(H – X) + mgXE = mg(H – X + X)E = mgHSimilarly, if we see the energy at point C which is at the bottom of the tree, it will come out to be mgH. K.E = P.E=> P.E = K.E = E2 ——– (4)E2 is the new energyWhere, E = mgH2H2 is the new height.As the body is at height X from the ground,P.E = mgX ——— (5)Using (4) and (5) we get,mgX=mgH2⇒X=H2H2 is referred to the new height \tProof for Law of Conservation of Energy:Considering the potential energy at the surface of the earth to be zero. Let us see an example of a fruit falling from a tree.Consider a point A, which is at some height ‘H’ from the ground on the tree, the velocity of the fruit is zero hence potential energy is maximum there.E = mgH ———- (1)When the fruit is falling, its potential energy is decreasing and kinetic energy is increasing.At point B, which is near the bottom of the tree, the fruit is falling freely under gravity and is at a height X from the ground, and it has a speed as it reaches point B. So, at this point it will have both kinetic and potential energy.E = K.E + P.EP.E = mgX ——— (2)According to third equation of motion,v2=2g(H–X)⇒12mv2=12m.2g(H–X)⇒K.E=12m.2g(H–X)⇒K.E=mg(H–X)K.E=mg(H-X)——– (3)Using (1), (2) and (3)E = mg(H – X) + mgXE = mg(H – X + X)E = mgHSimilarly, if we see the energy at point C which is at the bottom of the tree, it will come out to be mgH. We can see as the fruit is falling to the bottom and here, potential energy is getting converted into kinetic energy. So there must be a point where kinetic energy becomes equal to potential energy. Suppose we need to find that height ‘x’ from the ground. We know that at that point,K.E = P.E=> P.E = K.E =\xa0E2\xa0——– (4)E2 is the new energyWhere, E = mgH2H2 is the new height.As the body is at height X from the ground,P.E = mgX ——— (5)Using (4) and (5) we get,mgX=mgH2⇒X=H2H2 is referred to the new height\t\xa0 It neither be created nore be destroied. It convert into another type of energy |

Explain Newton 3 law of motion with example? |
|
Answer» Third low of motion: To every action there is an equal and opposite reaction and they act on two different bodies. Example,when air rushes out of a balloon,the opposite reaction is that the balloon flies up. It states that every action has an equal and opposite reaction It states thatEvery action has equal and opposite reaction . For example :- when a sailor jumps from a boat. As the sailor jumps forward, the boat moves backward |

What are 3 laws of motion |
|
Answer» First law. If the object is in motion or rest it will continue in the same state unless any externalforce is provided Second law. Force directly change in momentum upon time taken. Third law. Every action has equal and opposite reaction 3rd law :- it states that every action has an equal and opposite reaction First law-:every object stays in state of rest or uniform motion until or unless some external force Is applied on objectSecond law -:the rate of change of momentum is directly proportional to unbalanced force applied over an object and the object moves in direction of unbalanced force acting over an object Third law -:on any object action and reaction are two equal and opposite forces First law: an object will continue to be in the state of rest or in uniform motion until and unless and unbalanced force is applied on it it is now also known as Law of InertiaSecond law: the rate of change of momentum is directly proportional to the force applied in the direction of forceThird law: to every action there is an equal and opposite reaction |
