According to Swami Vivekananda every improvement in India require first of all an upheaval in religion. In his travels, he found that for the uplift of nation it was necessary to energize the masses which could be achieved only by religion, rejuvenated and revitalized by infusing Vedantic ideas. “In religion,” he said, “lies the vitality of India and so long as the Hindu race do not forget the great inheritance of their forefathers, there is no power on earth to destroy them.” He wanted a religion which would “give us faith in ourselves, a national self-respect and the power to feed and educate the poor and relieve the misery around us. According to him the problems of India are more complicated, more momentous than the problems in any other country. Swamiji’s plan for the elevation of the masses was to give them secular education and to prepare them to work for a better standard of life. But in his view this secular education was to be imparted through religion, for it was only through religion that even ideas of social and political advancement take root in India. “Keep the motto before you,” he said, “elevation of the masses without injuring religion.” Religion was getting confined to don’t touchism, the kitchen and the cooking pot, and Swami Vivekananda wanted to reinstate, pristine Upanishadic religion.” His beautiful summing up of what religion means deserves’ thoughtful consideration. “Each soul is potentially divine. The goal is to manifest this Divinity within by controlling Nature, external and internal. Do this either by work or worship, or psychic control or philosophy—by one or more or all of these and be free. This is the whole of religion. Doctrines or dogmas or rituals or books or temples or forms are but secondary details.”1. What, according to Vivekananda, does cause upheaval in religion in India?2.

The first characteristic of Bharatiya culture is that it looks upon life as an integrated whole. It has an integrated viewpoint. To think of parts may be proper for a specialist, but it is not useful from the practical standpoint. The confusion in the West arises primarily from its tendency to think of life in sections and then to attempt to put them together by patch-work. We do admit that there is diversity and plurality in life, but we have always attempted to discover the unity behind them. This attempt is thoroughly scientific. The scientists always attempt to discover the unity behind them. This attempt is thoroughly scientific. The scientists always attempt to discover order in the apparent disorder in the universe, to find out the principles governing the universe and frame practical rules on the basis of these principles. Chemists discovered that a few elements comprise the entire physical world. Physicists went one step further and showed that even these elements pulsate with energy. Today we know that the entire universe is only a form of energy.Philosophers are also basically scientists. The western philosophers reached up to the principle of duality; Hegel put forward the principle of thesis, anti-thesis and synthesis.Karl Marx used this principle as a basis and presented his analysis of history and economics. Darwin considered the principle of survival of the fittest as the sole basis of life. But we, in this country, perceived the basic unity of all life. Even the dualists have believed nature and spirit to be complementary to each other than contradictory. The diversity in life is merely an expression of the internal unity. There is complementarity underlying the diversity. The unity in seed finds expression in various forms—the roots, the trunk, the branches, the leaves, the flowers and the fruits of the tree. All these have different forms and colours and even to some extend different properties. Still we recognise their relation of unity with each other through the seed.1. How does Bharatiya culture look upon life?2. How does the West look upon life?3. What do the scientists always attempt to discover?4. What did the Chemists and the Physicist discover?5. Which principles about life was given by Darwin?6. In what forms does the unity in seed find expression?7. What have even the dualists believed?8. Locate from the passage the words that have the following—(i) obvious(ii) variety. |

In how many ways can three numbers be chosen from the set {1,2,3,...,12} such that their sum is divisible by3 ? |
|
Answer» Let A = {1, 2, 3, ......, 12}. Let's define a new set B, where B[n] = A[n] mod 3 Then B = {1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0} For the sake of clarity, I'm going to lebel each number with a subscript letter. (like 4 mod 3 = (1 x 3 + 1) mod 3 = lb and 7 mod 3 = (2 x 3 + 1) mod 3 = 1) Then B = {1a, 2a, 0a, 1b, 2b, 0b, 1c, 2c, 0c, 1d, 2d, 0d}. There are 4 zeroes, 4 ones and 4 twos. Case I : 0 + 0 + 0 = 0 (mod 3) Total possibilities of that case are \(4_{c_3}\) = 4 Case II : 0 + 1 + 2 = 3 mod 3 = 0 Total possibilities of that case are \(4_{c_1}\times4_{c_1}\times4_{c_1}\) = 4 x 4 x 4 = 64 Case III : 1 + 1 + 1 = 3 mod 3 = 0 Total possibilities of that case are \(4_{c_3}\) = 4 Case IV : 2 + 2 + 2 = 6 mod 3 = 0 Total possibilities of that case are \(4_{c_3}\) = 4 Therefore, total ways to selecting 3 numbers from set {1, 2, 3 ..... 12} whose sum is divisible by 3 = 4 + 64 + 4 + 4 = 76 |

What do you understand by voltage stabilization? How is it achieved? |
|
Answer» Voltage stabilization is a method of stabilizing the voltage against voltage fluctuations. This is achieved using voltage stabilizer. It is an electrical appliance that feeds constant voltage to a load during over and under voltage conditions. This device detects these voltage conditions and correspondingly brings the voltage to desired range. Voltage stabilizers provide a means to regulate the supply voltage to the load. The voltage regulation is required for two distinct purposes; over voltage and under voltage conditions. The process of increasing voltage from under voltage condition is called as boost operation, whereas reducing the voltage from overvoltage condition is called as buck operations. These two main operations are essential in each and every voltage stabilizer. |

Describe Schafer’s Method of artificial respiration. |
|
Answer» The subject is laid in prone position and a small pillow is placed underneath the chest and epigastrium. The head is turned to one side. The operator kneels down by the side of the subject facing towards his head. Two hands are placed on the two sides of the lower part of the chest and then the operator slowly puts his body weight leaning forwards and pressing upon the loins of the subject. Intra-abdominal pressure rises, the diaphragm is pushed up and air is forced out of the lungs. After this the operator releases the pressure and comes back to his original erect position. The abdominal pressure falls, diaphragm descends and air is drawn in. These movements are repeated about twelve times a minute. |

Explain Nelson’s Arm method of artificial respiration. |
|
Answer» The purpose of artificial ventilation is to provide a method of air exchange until natural breathing is established. Artificial ventilation should be given only when natural breathing has stopped; BACK PRESSURE ARM LIFT.—This method is an alternate technique used when other methods are not possible. Place the victim on the stomach, face to one side, neck hypo-extended, with hands under the head. Quickly clear the mouth of any foreign matter. Kneel at the victim's head and place your hands on the victim's back so that the heels of the hands lie just below a line between the armpits, with thumbs touching and fingers extending downward and outward. Rock forward, keeping your arms straight, and exert pressure almost directly downward on the victim's back, forcing air out of the lungs. Then rock backward, releasing the pressure and grasping the arms just above the elbows. Continue to rock backward, pulling the arms upward and inward (toward the head) until resistance and tension in the victim's shoulders are noted. This expands the chest, causing active intake of air (inspiration). Rock forward and release the victim's arms. This causes passive exiting of air (expiration). Repeat the cycle of press, release, lift, and release 10 to 12 times a minute until the victim can breathe naturally. |
