explain how human ear work? |
|
Answer» the outer ear or pinna helps to collect sound and passes to the middle ear. In the middle ear, the ear canal passes the sound to the ear drum. The ear drum vibrates and vibrates as the sound is emitted by the source and passes the vibration to hammer. Hammer passes the vibration to anvil and anvil passes the vibration to stirrup. Stirrup passes it to cochlea which passes it to auditory nerves which changes these vibrations into electric signal and passes it to the brain. The brain interprets these vibrations into sound. Working of Human Ear\tSound waves are collected by the pinna and then are directed through ear canal sound waves on striking the eardrum make it vibrate exactly the same way as the given sound emitting object.\tThe bones in thge middle ear start vibrating when eardrum vibrates. It helps in magnifying the vibrations. When the magnified vibrations reach the cochlea in the inner ear, the fluid in it starts vibrating.\tThese vibrationsare picked up by sensory receptors and are converted into electrical signals.\tThese electrical signals then travel to the brain which interprets sound. |

What are the advantages of inter-cropping and crop rotation? |
|
Answer» Inter-cropping and crop rotation are used to obtain maximum benefit. Inter-cropping helps in preventing pests and diseases to spread throughout the field. It also increases soil fertility, whereas crop rotation prevents soil depletion, increases soil fertility, and reduces soil erosion. Both these methods reduce the need for fertilizers. It also helps in controlling weeds and controls the growth of pathogens and pests in crops. Ytfrr7erhffsfet |

Newton\'s Three law of motion |
| Answer» Newton first law of motion according to Newton first law of motion a body continues to be in state of rest or in a state of motion until unless some external unbalance force is appliedaccording to Newton\'s second law of motion the law of change of Linear Momentum of a body is directly proportional to force and this change always take place in the direction of the force. F=maaccording to Newton\'s third law of motion every force has equal and opposite reaction that is force of action and reaction are always equal and never cancel each other and this force act on two different bodies.Fab=-fbaforce applied on a to b is equal to minus force applied on b2a | |

Absolute charge on electron?? |
| Answer» Electron is a negatively charged particle having an absolute charge of - 1.6 x 10-19\xa0coulombs. Since this is the smallest negative charge carried by a particle, so this is taken as the unit of negative charge, and we say that the relative charge of an electron is - 1. The charge of an electron is equal in magnitude but opposite in sign to the charge of a proton. A normal atom has an equal number of protons and electrons and since a proton and an electron have equal and opposite charge, an atom on the whole is electrically neutral. Electron is the lightest of the three atomic particles. | |

Why we don\'t hear sound whose frequency is more than 20,000 hertz? |
| Answer» In general terms, the frequency range for human hearing is about 20 Hz - 20,000 Hz (at least in “normal hearing young adults”). The response of the ear is governed, in part, by the mass and elasticity of the eardrum, muscles and ligaments, bones, and fluid and structures in the inner ear. Elasticity opposes low frequency sounds, while mass opposition increases as frequency increases. So both mass and elasticity set limits for frequency range. As an interesting aside, an object will resonate at a frequency where elastic opposition has decreased and mass opposition isn’t too high. For human ears, its about 2000–4000 Hz. So those frequencies are amplified for us…important, because that’s the range where speech sounds are heard to maximize understanding of speech. | |

State the significance of membrane biognesis |
| Answer» The process of formation of the biological membranes is called membrane biogenesis. The endoplasmic reticulum is responsible for the synthesis of these membranes.Membrane biogenesis involves the synthesis of cell membrane with the help of proteins and lipids. Endoplasmic reticulum is responsible for the synthesis of these membranes.Membranes synthesised by this process of membrane biogenesis help in dividing the cell into structural and functional compartments. Membranes of the cell altogether are called as endomembrane system. The endomembrane system includes different membranes suspended in the cytoplasm and the plasma membrane. | |

Explain gaseous exerts pressure on the wall of the container. |
|
Answer» Gas exert pressure on the walls of the container because when container is heat up the particles of gas strike against the walls of the container therefore they exert some force per unit area which is equal to the pressure Because the gas have high knetic energy and negligible force of attraction so they strik the wall with the certain firce impart momentum to them tge monentum is respinsible for the pressure |

Write down the mathematical derivation of both potential and kinetic energy |
| Answer» Let the work done on the object against gravity = WWork done, W = force ×\xa0displacementWork done, W = mg\xa0×\xa0hWork done, W = mghSince workdone on the object is equal to mgh, an energy equal to mgh units is gained by the object . This is the potential energy (Ep) of the object.\xa0Ep = mghDerivation for the equation of Kinetic Energy:The relation connecting the initial velocity (u) and final velocity (v) of an object moving with a uniform acceleration a, and the displacement, S is\xa0\xa0v2 - u2 = 2aSThis gives \xa0S = (v 2 - u 2)/ 2aWe know F = ma. Thus using above equations, we can write the workdone by the force, F as W = ma ×{ v 2 - u 2/ 2a} or\xa0W = 1 /2 m( v 2 - u 2 )If object is starting from its stationary position, that is, u = 0, thenW = 1/2 m v 2It is clear that the work done is equal to the change in the kinetic energy of an object.If u = 0, the work done will be W = 1/2 m v 2 .Thus, the kinetic energy possessed by an object of mass, m and moving with a uniform velocity, v is Ek = ½ mv2 | |

Difference between soft sounds and loud sound |
| Answer» Greater the amplitude of the sound, the louder is the sound. Whereas soft sound refers to sounds having low amplitude.Normally if we see the difference between sound and loud sound is the intensity of sound. If we look at its application the sound of a DJ may sound nice from a distance but when we go closer it becomes noise. The sound we enjoy becomes music, but that we do not enjoy becomes noise.\xa0 | |
