At last, Andrew Manson had some sense of satisfaction. He had saved a precious life. He was a young doctor. Being a doctor, it was his duty to save a life. He saved not one but two lives. First of all, he gave a new lease of life to Susan Morgan. He brought her to safety. But his most creditable work was the saving of Susan’s child. The nurse had put the stillborn child into a heap of old newspapers beneath the bed. She had almost considered him dead. The saving of the child from the sure jaws of death was nothing less than a miracle. Doctor Andrew Manson was able to perform that miracle. He

It is given that required number which divides 245 and 1029, the remainder is 5 in each case.
⇒ 245 - 5 = 240 and 1029 - 5 = 1024 are completely divisible by the required number.
Since, it is given that the required number is the largest number.
Therefore, it is the HCF of 240 and 1024.
Now, finding HCF by Euclid’s division algorithm.
Given integers are 240 and 1024.
Clearly 1024 > 240.
Therefore, it is the HCF of 240 and 1024 and 240, we getII. Since, the remainder 64 ≠ 0, we apply division lemma to getIII. We consider the new divisor 64 and remainder 48 and apply division lemma to ge

Physical development: Development of organ systems such as circulatory system, nervous system, muscular system, digestive system etc.
Mental development: Physical activities require alertness of mind, deep concentration and calculated movement. This objective is related to the mental development of an individual.
Social development: This objective is related to the development of social traits, which are essential for better adjustment in life. It is a better source for attaining the qualities like. Co-operation, fair play, sportsmanship, tolerance, and sympathy.

अलवार, नयनार और वीरशैव दक्षिण भारत में उत्पन्न विचारधाराएँ थी। इनमें अलवार, नयनार व तमिलनाडु से सम्बन्ध रखते थे, वही
वीरशैव कर्नाटक से सम्बन्ध रखते थे। इन्होंने जाती प्रथा के बंधनों का अपने-अपने ढंग से विरोध किया.
4. अलवार और नयनार संतों ने जाति प्रथा व ब्राह्मणों की प्रभुता के विरोध में आवाज़ उठाई। यह बात सत्य प्रतीत होती है क्योंकि भक्ति

Number of electrons in N3- = 7+3 = 10Number of electrons in O2- = 8+2 = 10Number of electrons in F- = 9+1 = 10Since, all the three species have each 10 electrons hence they are isoelectronic species.It is considered that, in case of isoelectronic species as the negative charge increase, ionic radii increase and therefore the value of ionic radii areN3- = 1.71 (highest among the three)O2- = 1.40F- = 1.36 (lowest among the three)N3- > O2-> F-

The earth’s surface is covered with water, but only a small proportion of it accounts for freshwater that can be put to use. This freshwater is mainly obtained from surface run off and ground water that is continually being renewed and recharged through the hydrological cycle. All water moves within the hydrological cycle ensuring that water is a renewable resource.

The transport system in highly organised plants consists of two components:(i) Xylem: Consists of vessels, tracheids and other xylem tissues. The interconnected vessels and tracheids form a continuous system of water conducting channels reaching all parts of the plant. Xylem conducts water and dissolved minerals absorbed from the soil.(ii) Phloem: Consists sieve tubes and companion cell which conduct soluble products of photosynthesis from leaves to different parts of the plant body. This transportation of prepared food material through pholem is called translocation.

Seemapuri is still in wilderness but it is no longer empty. In 1971 it was inhabited illegally by more than 10,000 rag-pickers from Bangladesh in 1971. It is on the periphery of Delhi yet it is miles away from it metaphorically. People live in structures of mud, with roofs of tin and tarpaulin. It is devoid of sewage, drainage and running water. They have got ration cards for votes and buying grains. They have no identity. Women move in tattered saris. Survival in Seemapuri means rag-picking.

The difficulties that one would face in classification of animals if common fundamental features are not taken into account are as following:(i) Animal kingdom consists of a large number of organisms. If the common fundamental characteristics are not considered for classification, each organism will have to be placed in a different group. Thus, the study of the organisms would become nearly impossible and it would be very tough.(ii) Without common fundamental features, it would be very difficult to segregate the organisms into groups.(iii) Without segregation into groups, comparing different

i) Underlying principle of a step-up transformer: A transformer which increases the ac voltage is known as a step up transformer.
Working of step-up transformer is based on the principle of mutual inductance and it converts the alternating low voltage to alternating high voltage. The number of turns in the secondary coil is greater than the number of turns in the primary coil.

नवाब साहब ने बहुत नजाकत और सलीके से खीरा काटा, उन पर नमक-मिर्च लगाया। उन नमक-मिर्च लगी खीरे की फाँकों को खाया नहीं अपितु सूँघकर खिड़की से बाहर फेंक दिया था। उनकी इस हरकत का यह कारण होगा कि वे एक नवाब थे, जो दूसरों के सामने खीरे जैसी आम खाद्‌य वस्तु खाने में शर्म भव करते थे। लेखक को अपने डिब्बे में देखकर नवाब को अपनी रईसी याद आने लगी। इसीलिए उन्होंने खीरे को मात्र सूँघकर ही खिड़की से बाहर फेंक दिया।
नवाब साहब के ऐसा करने से ऐसा लगता है कि वे दिखावे की जिंदगी जी रहे हैं। वे दिखावा पसंद इंसान थे। उनके इसी प्रकार के स्वभाव ने लेखक को देखकर खीरा खाना अपमान समझा।

The equation of the line 5x-25 =14-7y =35z can be rewritten asSince the required line is parallel to the given line, so the direction ratio of the required line is proportional to 7,-5,1The vector equation of the required line passing through the point (1,2-1) and having direction ratios proportional to 7,-5 1 is

Crystal Field Splitting Energy: Crystal field theory was given to explain the structure and stability of the coordination complexes. This theory has some assumption like the metal ion is considered to be a point positive charge and the ligands are negative charge. The complexes are formed mainly by the d- block elements due to their variable oxidation states and variable coordination number. The d- subshell has 5 degenerate orbitals. when the ligand approach to the metal ion, the energy of the degenerate orbitals is increased and further splitting of degenerate orbital takes place into t2g an
