Main characteristic of series circuit and parallel circuit |
| Answer» Characteristics of series circuits: \tcurrent is the same everywhere (ammeter operation)IT = I1 = I2 =I3\tvoltage is different across different resistancesVT = V1 + V2 + V3 (voltmeter operation)\ttotal resistance is equal to the sum of the resistancesR = R1 + R2 + R3\ta break in the circuit stops all currentCharacteristics of parallel circuits:\xa0\tcurrent is different in different resistances, but the total current is equal to the sum of the currents in all the branchesIT = I1 + I2 + I3\tvoltage is the same across all resistancesVT = V1 = V2 =V3\ttotal resistance is less than the sum of the individual resistancesVT/RT = V1/R1 +V2/R2 + V3/R31/RT = 1/R1 + 1/R2 + 1/R3\ta break in the circuit only stops current in the branch where the break occurs | |

Explain the structure of eye |
| Answer» Eye is the most important organ of our body. It consists of a tough fibrous membrane called sclera that protects the internal parts of the eye. Cornea is the membrane covering the front of the eye that is bulged out and is responsible for the maximum refraction of the light that enters the eye. Behind it lies aqueous humour that enables the eye to cope up with the atmospheric changes. Iris forms the coloured part of the eye. It adjusts the size of the pupil, thereby controls the amount of light entering the eye. Behind it lies the crystalline lens, a biconvex structure that helps in fine adjustment to the refracted light so that it is focused on the screen of the eye, which is referred to as retina. Ciliary muscle helps in adjusting the focal length of the lens by contraction or relaxing. Behind the lens lies vitreous humour which is a dense, clear, jelly like fluid which helps to maintain the shape of the eye and focus the image clearly on the retina.Retina is actually a canopy of the nerve endings of the optical nerve through which images are converted into electrical impulses and transferred to the brain for realization of the image. The eye can focus near objects as well distant objects and this is accommodation of the eye. The minimum distance of the object at which an eye can focus clearly is the near point the maximum is called the far point. If an eye is unable to focus the nearby objects and is able to view clearly the far off objects, the defect is called hypermetropia or long sightedness and can be corrected by a suitable convex lens. On the other hand if a person is able to view the nearby objects clearly and unable to view the distant objects the defect is myopia or short sightedness and can be corrected by a suitable concave lens. The power of the corrective lens is calculated by using lens formula and is measured in dioptre. | |

Why current flow from+ve to -ve ?Its right question and science is depend on why. |
|
Answer» It is generally depends on p and s type semiconductor The flow of electrons is termed electron current. Electrons flow from the negative terminal to thepositive. Conventional current or simply current, behaves as if positive charge carriers cause currentflow. Conventional current flows from the positive terminal to the negative. Perhaps the clearestway to think about this is to pretend as if movement of positive charge carriers constituted currentflow.It is important to realize that the difference between conventional current flow and electron flowin no way effects any real-world behavior or computational results. In general, analyzing anelectrical circuit yields results that are independent of the assumed direction of current flow. Con-ventional current flow is the standard that most all of the world follows. |

Write the chemical equestion of ranciditiy |
| Answer» When fats and oils are oxidised, they become rancid and their smell and taste is changed. This is called Rancidity. Usually substances which prevent oxidation (antioxidants like Nitrogen, B.H.T.) are added to foods containing fats and oil. Keeping food in air tight containers helps to slow down oxidation or Rancidity.There Is No Reaction Of Rancidity It Is Just A Process Of Spoiling. | |

What is photo respiration |
| Answer» Photorespiration is the process where oxygen is consumed, food is oxidized and carbondioxide is liberated, but no energy is produced.

What would be the consequences of deficiency of haemoglobin in our bodies? |
| Answer» \xa0Haemoglobin is the respiratory pigment that transports oxygen to the body cells for cellular respiration. Therefore, deficiency of haemoglobin in blood can affect the oxygen supplying capacity of blood which leads to deficiency of oxygen in the body cells. It can also lead to a disease called anaemia. | |

Why magnetic field line are uniform. |
|
Answer» Ye to pta h ...... but tedha medha kuy nhi nikle skta . Matlb ek magnet bnao , then jo north pole se field line niklega use tedha -medha bnao or south me le jao. When magnetic field lines are parallel then magnetic force experienced by an object is same at all points in that field and such a field is called uniform magnetic field. For example a bar magnet\'s strength is greater at its poles[non uniform] however inside a solenoid the magnetic field lines are parallel.??? Give me reason. Ye thedha medha bhi to ho skta h. |
