Appriciate the role of subhas Chandra Bose

Answer»
. Subhash Chandra Bose looked at the opportunity made available by the difficulties of the British. He said that India's independence was of utmost importance and we should take the help of the Japanese to throw out the British. He went secretly to Germany and then to Japan and raised an army of Indian soldiers in 1942. In the beginning they were soldiers in the British army and had been captured by the Japanese when the British were defeated in Burma and Malaya. They were POWS (prisoners of war). Bose recruited them in his army which he called the Indian National Army (INA). Later, other indians also joined the army including many women. However, Gandhi did not agree with the plans of Bose and felt that the Japanese cannot be the liberators of India. But Subhash persisted in his chosen path and led an army of Indian soldiers to fight alongside the Imperial Army of Japan against the British for almost three years.
Bose was sent to prison in Mandalay for nationalist activities in 1925. He was released in 1927 and became the INC’s general secretary.
He worked with Jawaharlal Nehru (Born on November 14 – 1889) and the two became the Congress Party’s young leaders gaining popularity among the people.
He advocated complete Swaraj and was in favour of the use of force to gain it.
He had differences with Gandhi and he wasn’t keen on non-violence

Netaji Subhas Chandra Bose set up the Azad Hind government on October 21, 1943. Where?

Answer»

Cathay Cinema House in Singapore

20.

Read the passage carefully: 1. Subhas Chandra Bose fulfilled a promise to his father that he would sit for the Indian Civil Service examination in London. He secured the fourth position in 1920 but then went on to fulfill his own wish. He resigned from the coveted service the following year, saying “only on the soil of sacrifice and suffering can we raise our national edifice”. Returning to India, he plunged into the national struggle and by 1923, was secretary of the Bengal State Congress and President of All India Youth Congress. 2. By 1927, he emerged, along with Jawaharlal Nehru, as leader of the new youth movement, which came into its own by playing a major role in the anti-Simon Commission agitation which swept India that year. He was also the chief organizer of the Calcutta session of the Indian National Congress (INC) in December 1928, which demanded that the goal of the congress be changed to ‘PurnaSwaraj’ or ‘Complete Independence’. 3. Imprisonment in the Civil Disobedience movement followed by bad health in 1932 took him to Europe where he observed European politics, particularly Fascism under Mussolini and Communism in the Soviet Union. He was impressed by both and believed that authoritarian rule was essential for achieving radical social goals. 4. In fact, it is in this period that political views of Nehru and Bose begin to diverge sharply, especially on the issue of Fascism and Nazism. Nehru was so vehemently opposed to Fascism that he refused to meet Mussolini even when the latter sought him out, whereas Bose not only met Mussolini but was impressed by him. Nehru was sharply critical of the growing danger to the world from the rise of Hitler. Bose, on the other hand, never expressed that kind of aversion to Fascism, and was quite willing to seek the support of Germany and later Japan against Britain. However, he was not happy with the German attack on Soviet Union in 1941, and that was one reason why he left Germany for Japan. For Bose, Socialism and Fascism were not polar opposites, as they were for Nehru. 5. In 1938, Bose was unanimously elected, with the full support of Gandhiji, as Congress president for the Haripura session. But the next year, he decided to stand again, this time as a representative of militant and radical groups. An election ensued which Bose won by 1,580 to 1,377 votes, but the battle lines were drawn. The challenge he threw by calling Gandhian leaders rightists who were working for a compromise with the British government was answered by 12 members of the working committee resigning and asking Bose to choose his own committee. Nehru did not resign with other members but he was unhappy with Bose’s casting of aspersions on senior leaders. He tried his best to mediate and persuade Bose not to resign. 6. The crisis came to a head at Tripuri in March 1939, with Bose refusing to nominate a new working Committee and ultimately resigning. The clash was of policy and tactics. Bose wanted an immediate struggle led by Gandhiji, whereas Gandiji felt the time was not ripe for struggle. 7. Having burnt his boats with the Congress. Bose went and then to Japan in 1943 to seek help in the struggle against their common enemy, Britain. He finally went to Singapore to take charge of the Indian National Army (INA) which had been formed by Mohan Singh in 1941 from Indian prisoners of war captured by the Japanese. The INA was clear that it would go into action only on the invitation of the INC; it was not set up as a rival Centre of power. Bose made this more explicit when on July 6, 1944, in a broadcast on Azad Hind Radio addressed to Gandhiji, he said, “Father of our Nation! In this holy war of India’s liberation, we ask for your blessing and good wishes”.On the basis of your understanding of the passage answer the following questions with the help of the given options :(a) Subhas Chandra Bose was secretary of the (i) Bengal State Congress (ii) All India Youth Congress (iii) Central India Youth C(b) In which year Subhas Chandra Bose was imprisoned in the Civil Disobedience Movement (i) 1928 (ii) 1930 (iii) 1932 (iv) 1934(c) Subhas Chandra Bose was not happy with the (i) Soviet Union attack on German in 1941 (ii) German attack on Soviet Union in 1941 (iii) Soviet Union attack on Japan in 1941 (iv) Japan attack on Soviet Union in 1941(d) Indian National Army (INA) was formed by (i) Mohan Singh (ii) Subhash Chandra Bose (iii) Jawaharlal Nehru (iv) Mahatma GandhiAnswer the following question briefly:(e) Why did Subhash Chandra Bose resign from the Indian Civil Services?(f) Who all played a major role in the Anti-Simon Commission agitation?(g) What was the demand of Indian National Congress in December 1928?(h) What were the issues which lead to differences in political views of Nehru and Bose?(i) When was Subhash Chandra Bose elected as Congress President and with whose support?(j) What was the address by Bose to Gandhiji on Azad Hind Radio?(k) Find words from the passage which means the same as:(i) to be in jail (Para 3) (ii) to elect a leader

Which of the following statement is NOT Correct?If an object sinks in water, it means that:1. The upper thrust of water on the object is less than the weight of the object.2. The density of object is less than the density of the water.3. The density of an object is greater than the density of water.4. The overhead of water on an object is greater than the weight of the object.

Answer» Correct Answer - Option 2 : The density of object is less than the density of the water.

The correct answer is The density of the object is less than the density of the water.

The incorrect statement is The density of the object is less than the density of the water.

  • If an object sinks in water, it means that the upper thrust of water on the object is greater than the weight of the object.
  • Whether an object will float or sink in another substance is decided by the density of an object.
  • If an object is less dense than the liquid, then the object will float in that liquid.

  • The characteristic property of an object is density.
  • Density does not depend on the amount of substance.
  • Density measures how heavy something is as compared to its size.
  • The size, shape, or type of material does not decide that if the substance will flow or sink in the liquid.
  • Some trapped air is contained by all objects that float in the liquid.
  • Archimedes principle:The principle of Archimedes states “When a body is immersed in a liquid, an upward thrust, equal to the weight of the liquid displaced, acts on it.”

  • Do not get confused in this question, as the question is asking an INCORRECT statement. 
  • If an object sinks in water then it is due to its higher density as compared to water, therefore the density of an object is greater than the density of water is a correct statement.
  • And the density of an object is less than the density of water is clearly a false statement.

The heat of combustion of ethanol into carbon dioxides and water is –327 kcal at constant pressure. The heat evolved (in cal) at constant volume and 27°C (if all gases behave ideally) is (R = 2 cal mol–1 K–1)

Answer»

C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l)

Δng = 2 – 3 = –1

ΔcH = ΔcU + (Δng) RT

ΔcH = ΔcU – RT

ΔcU = ΔcH + RT

= –327 × 103 + 2 × 300

= –326400 cal.

Heat evolved

= 326400 cal.

State the function of placenta in humans. List the hormone secreted by it

Answer»

The placenta is the highly specialised organ of pregnancy that supports the normal growth and development of the fetus. Growth and function of the placenta are precisely regulated and coordinated to ensure the exchange of nutrients and waste products between the maternal and fetal circulatory systems operates at maximal efficiency. The main functional units of the placenta are the chorionic villi within which fetal blood is separated by only three or four cell layers (placental membrane) from maternal blood in the surrounding intervillous space. After implantation, trophoblast cells proliferate and differentiate along two pathways described as villous and extravillous. Non-migratory, villous cytotrophoblast cells fuse to form the multinucleated syncytiotrophoblast, which forms the outer epithelial layer of the chorionic villi. It is at the terminal branches of the chorionic villi that the majority of fetal/maternal exchange occurs. Extravillous trophoblast cells migrate into the decidua and remodel uterine arteries. This facilitates blood flow to the placenta via dilated, compliant vessels, unresponsive to maternal vasomotor control. The placenta acts to provide oxygen and nutrients to the fetus, whilst removing carbon dioxide and other waste products. It metabolises a number of substances and can release metabolic products into maternal and/or fetal circulations. The placenta can help to protect the fetus against certain xenobiotic molecules, infections and maternal diseases. In addition, it releases hormones into both the maternal and fetal circulations to affect pregnancy, metabolism, fetal growth, parturition and other functions. Many placental functional changes occur that accommodate the increasing metabolic demands of the developing fetus throughout gestation.

Placenta is the temporary endocrine organ formed during pregnancy. It connects foetus to the utrine wall through umbilical cord. It is the organ by which nutritive, excretory functions are fullfilled .
