A 4 ohm resistence wire is doubled on it then calculate the new resistence |
|
Answer» 4×2=8 Hence the new resistence is 8ohm Let the original length of wire be -l And area of cross section be -A Since given resistance -4ohm We know R=pl/A. (1)(we know v=Al therefore A=V/l) (2) Now substituting (2) in (1) R=pl/V/l Therefore R=pl*2(l square) /V (3) Let new resistance be R\' And new length = 2l So R\'= p2l/A. (4) Substituting (2) in (4) R\'=p(2l)*2 (2l square) /vR\'=p4l*2/vR\'=4pl*2/v Therefore R\'=4RR\'=16ohm |

What is gestation period in human? Explain. |
| Answer» The time period from fertilization to childbirth is called the gestation period.\tThe time from fertilization to parturition is termed as gestation-period. Rabbit has gestation-period of 28-30 days. In one time 4-6 young-ones are born in rabbit (Maximum = 8). The group of young-ones born the at same time are called Litter. At the time of birth the young ones of rabbit are blind, deaf and uncovered with fur.\tThey become normal in next 4-5 days. The young-ones of Hare are normal at the time of birth. In humans actual gestation period is 9 months –7 days.\tIn human expected date of delivery (EDD) = Ist day of last menstrual cycle plus 9 months + 7 days. | |

why is carbon not used for reducing aluminium from aluminium oxide? |
| Answer» Carbon isn\'t utilized for diminishing aluminum oxide since aluminum is more responsive than carbon. Thus, carbon can\'t uproot aluminum from its oxide. Aluminum oxide is exceptionally steady and Carbon is less responsive than aluminum, hence it can\'t be utilized to diminish aluminum oxide to aluminum metal. | |

Why are some food items stored in cold stores while others are stored in normal places |
| Answer» Some food items are stored in cold stores while others are stored in normal places; because perishable food items like fruits, vegetables, fresh meats, etc deteriorate easily in the normal temperature. If they are stored in low temperatures then the growth of the micro-organisms slows down along with the rate of chemical reactions in the food. Some other food items do not get spoiled at normal temperatures and hence kept at normal places. | |

Tissu culture |
| Answer» Tissue culture is the process of culturing single line cells under sterile, controlled conditions, in vitro by exposing them to nutrients, hormones and specific amount of sunlight. There are different steps involved in the tissue culture process.Step 1: Material is selected and sterilized for propagation of cells, in vitro initiating the process of culturing the cells.Step 2: The plant material is re-divided and placed in separate plates with medium rich in plant growth regulators. These growth regulators induce shoot formation. This process can be repeated till the desired number of plants is obtained.Step 3: The hormones which induce the formation of root are introduced into the medium. Now, complete plantlets are formed. These plantlets are transferred from lab into the green house for further growth. | |

Why carbon does not make C4+ and C4- |
| Answer» Atomic number of carbon is six. This means that it has four electrons in its outermost shell and it needs four more electrons to attain noble gas electronic configuration. The removal of four valence electrons will require a huge amount of energy and so it does not form C4+ cation, as the removal of four valence electrons will require a huge amount of energy. The cation formed will have six protons and two electrons. This makes it highly unstable. Carbon is unable to form C4- anion as its nucleus with six protons will not be able to hold ten electrons. Thus, carbon achieves noble gas electronic configuration by sharing its four electrons with other elements, i.e. it forms covalent compounds. | |
