Salt Satyagraha-1930:

On 12 March 1930, Gandhi started the Dandi march from Sabarmati Ashram towards the small coastal village of Dandi. He marched against the state monopoly in manufacturing and selling of salt. Gandhi chose salt because it was used in every Indian household, yet people were not allowed to make salt even for domestic use. This march was 370 Kms which included many small and large regions. Gandhiji told “I shall die the death of crow and dog, but I will not return to this Ashram without attaining Poorna Swaraj”. Gandhi after reaching dandi broke the salt laws by manufacturing salt. It led to the beginning of the Civil Disobedience Movement.
Jawaharlal Nehru:

Jawaharlal Nehru was born into an affluent Kashmiri Brahman family in Allahabad on November 14, 1889. Tutored at home until the age of 15, Nehru subsequently attended Harrow in England and, later, Trinity College, Cambridge. After studying law at London’s Inner Temple, he returned to India at the age of 22 where he practiced law with his father and prominent barrister, Motilal Nehru.

Upon learning of esteemed theosophist Annie Besant’s arrest in 1917, Nehru was moved to join the All India Home Rule League, an organization devoted to obtaining self-government within the British Empire. In April 1919, British troops opened fire on thousands of unarmed civilians who had been protesting recently passed legislation that permitted the detainment of suspected political foes without trial. The Massacre of Amritsar, in which 379 Indians were killed and more than a thousand others were wounded, outraged Nehru and further solidified his resolve to win India’s independence.

On August 15, 1947, India finally gained its independence and Nehru became the nation’s first prime minister. Amid the celebration of newly acquired freedom, there was also considerable turmoil. The mass displacement that followed partition into the separate nations of Pakistan and India, along with disputes over control of Kashmir, resulted in the loss of property and lives for several hundred thousand Muslims and Hindus.

Throughout his 17-year leadership, Nehru advocated democratic socialism and secularism and encouraged India’s industrialization beginning with the implementation of the first of his five-year plans in 1951, which emphasized the importance of increasing agricultural production. He also promoted scientific and technological advancements through the establishment of higher learning, and instituted various social reforms such as free public education and meals for Indian children, legal rights for women—including the ability to inherit property and divorce their husbands—and laws to prohibit discrimination based on caste.

During the Cold War, Nehru adopted a policy of non-alignment in which he professed neutrality, but was criticized when he refused to condemn the Soviet invasion of Hungary in 1956 and later requested foreign aid after China invaded India’s northern border in 1962. The conflict, known as the Sino-Indian War, had a deleterious effect on Nehru’s health, resulting in a severe stroke in January of 1964 and his death a few months later on May 27, 1964.

Interesting Facts

Why does a bird not get electrocuted on sitting on a live wire?

Birds, animals, and human beings can withstand flow of a certain amount of electric current through their bodies and excess flow of current will cause immediate death.

A bird sitting on a live wire will get electrocuted only if electric current passes through its body. We can compare flow of electricity through a body to flow of water through a pipe. Water will always flow from a higher level to a lower level. Similarly, electric current will always flow from a higher potential or voltage level to a lower potential level. We can see two wires running on poles through a street. One wire which we call live will be at a potential of 230 volts which is called the phase wire and the other one which we call the neutral wire will be at a potential of zero volts. Immediately on sitting on the live wire, the bird's potential will also be raised to 230 volts and if by an accident it comes in contact with the neutral wire or touches it, current will pass through its body from the live wire which is at a higher potential to the neutral wire which is at zero potential.

In the present case the flow of current through the bird's body will be enormous and the bird will be electrocuted.

If two crows, one sitting on the live wire and the other sitting on the neutral wire, happen to touch each other, both will be electrocuted and get burnt to death. But if both the birds sit on the live wire side by side and touch each other nothing will happen as both the crows will be at the same voltage level of 230 volts and there will be no flow of current through their bodies.

Why is the earthing pin in 3 pin electrical plugs bigger than the other two pins?

The earth wire starts from the metal body of the appliance and ends in the earth so it should never come into contact with live wire. In case the earth pin is connected wrongly with the live socket, the user touching the appliance might receive an electrical shock. The earthing pin being thicker in diameter compared to the other pins, can never enter the live or neutral sockets. Thus, the appliance can get connected only in a proper electrical position.

Secondly, the earthing pin is made longer than the other pins, so it gets connected to the earth terminal first before the other pins (live and neutral) make the contact in their respective sockets. This ensures safety of the user. In case there is a short circuit, due to loose contact, weak insulation or electric leak, as soon as the appliance is plugged in, the current from the electrical appliance flows to earth without harming the user. Hence it is always safe to install thick high-tension wires for earthing.

ANSWER FOR LAST WEEK QUESTIONS

1)Answer: Option(A) 16

Solution:

Volume of hemisphere = 2/3(πr³)

So, 2/3(πr³) = n*4*2/3(πr³)

2/3{π(8)³} = n*4*2/3{π(2)³}

Therefore, n = 16

2)Answer: Option(A) 35m East

Solution:

Rohit's distance from the starting point A would be

AE = AD + DE = 20 + 15 = 35m East

3) Answer: Option(A) 18 years

Solution:

Let the present age of the person be X years.

Then, 3(X + 3) - 3(X - 3) = X

3X+9-3X+9 = X

So, X = 18

4)Answer: Option(B) Ounce

Solution:

Yard is larger than inch (1 yard = 36 inches). In the same way, 1 quart = 32 ounces. i.e. quart is larger than ounce.

5)Answer: Option(D) Ruby

Solution:

As Diamond is the most valuable variety of the Carbon mineral, Ruby is the most valuable variety of the Corundum mineral.
