Precipitation that comes down to the earth in the liquid form is called rain. Most of the ground water comes from rain. Plants help in preserving water. A rain gauge measures the amount of rainfall.  

1. Using Exponent

<textarea data-settings="" readonly="readonly" wrap="soft"></textarea>

Output:

enter a number: 64
square root: 8.0

In above program, first we’re taking a number from user as input and the entered value will be converted to int from string and will store into variable called number. Then we are using  exponent (**) sign, which is used to find out the power of a number. But we know that if a number have power ½ or 0.5 then it will represent to the square root of that number. That’s why we are using 0.5 as power here. So the number**0.5 will give us square root of that number and will be stored in variable named as sqrt. In last line we’re just printing the square root of the number.

2. Using math.sqrt() Method

<textarea data-settings="" readonly="readonly" wrap="soft"></textarea>

sqrt() is the predefined method used to find square root in python. But we have to import math module to use the sqrt() method. In first line, we’re importing math module, then in next line, taking input from user. After that we’re finding the square root of the number using sqrt() method and result will be stored into sqrt variable. In last line, just printing the square root as in first program.

3. Using math.pow() Method

<textarea data-settings="" readonly="readonly" wrap="soft"></textarea>

pow() is also a predefined method to find out power of a number, it takes two arguments as input, first is the number itself and second one is power of that number. The program is same as first program where we’re using (**) sign to find out the square root but only different is this that here we’re using a predefined method pow() instead of  (**) sign to get the power of that number.

If you’ve any problem related with article or have any other possible way to find square root in python then please let us know in comments.

Cell: Cell is the basic structural and functional unit of living organism. Just as bricks is unit structure of house.

Each cell is capable of performing a basic function of life. Such as reproduction, respiration, excretion, growth, and so on.

The combined views of Schleiden and Schwann led to the formulation of the cell theory.

    The cell theory is also known as the cell doctrine or cell principle. It state:
1.All living organisms’ are made up of cells and their products.

2. All cells arise from pre- existing cell.

3. Cells are the structural and functional unit of all living organisms.

4. Cell is hereditary cells.

5. All cells are basically alike in chemical composition and metabolic activities.

6. Life passes from one generation to other generation in the form of a living cell.

• The name Methane determines that the hydrocarbon is having only one carbon atom in its compound.

• If a hydrocarbon has only one carbon atom it is impossible to form double or triple bonds in that hydrocarbon.

• To form double bondage or triple bondage in the hydrocarbon there must be 2 carbon atoms in that hydrocarbon of least.

• But we can have only one carbon in the hydrocarbons.

• So there will be no Methene or Methyne existing on nature even if we alter or manipulate the compounds.

Let given cubic polynomial be

p(x) = 3x³ - 5x² - 11x - 3

i ) If x = 3 , then

p(3) = 3(3)³ - 5(3)² - 11(3) - 3

= 81 - 45 - 33 - 3

= 81 - 81

= 0

ii ) If x = -1 , then

p(-1) = 3(-1)³ - 5(-1)² - 11(-1) - 3

= -3 - 5 + 11 - 3

= -11 + 11

= 0

iii ) If x = -1/3 , then

p(-1/3) = 3(-1/3)³ - 5(-1/3)² - 11(-1/3) - 3

= -3/27 - 5/9 + 11/3 - 3

= -1/9 - 5/9 + 11/3 - 3

= ( -1 - 5 + 33 - 27 )/9

= ( -33 + 33 )/9

= 0

Therefore ,

p(3) = p(-1) = p(-1/3) = 0 .

So, 3 , -1 , -1/3 are zeroes of given

cubic polynomial 3x³ - 5x² - 11x - 3 .

Compare the coefficients of given

cubic polynomial 3x³ - 5x² - 11x - 3

with ax³ + bx² + cx + d , we get

a = 3 , b = -5 , c = -11 , d = -3

Let the zeroes of the given cubic

polynomial p(x) are p =3 , q=-1, r=-1/3

Now ,

p+q+r = 3 - 1 - 1/3

= 2 - 1/3

= ( 6 - 1 )/3

= 5/3

= -b/a

pq+qr+rp

= 3(-1)+(-1)(-1/3)+(-1/3)(3)

= -3 + 1/3 - 1

= -4 + 1/3

= ( -12 + 1 )/3

= -11/3

= c/a

pqr = 3 × ( -1 ) × ( -1/3 )

= 1

=- d/a

With these words, Aparna Bidasaria conveys her response to the bargad or the banyan tree, the main theme of her acrylic on canvas works that were on display in the Capital recently. Cool, calm, relaxing — this is how it felt as one stepped into the Shridharani Art Gallery to see her show, titled Time and Being.

The Indore-based artist captures the beauty of the banyan tree using a fine blend of two styles of painting — pointillism and impressionism. She shows how breathtakingly beautiful and calming the banyan appears at different times of the day, if only we stop to see and learn.

The bargad also known as vata in Hindi and aal in Tamil is a unique tree, for it can grow up to 30 metres or more in height.

Owing to its aerial roots known as jatas, which grow on its branches and fall to the ground, giving it support and allowing it to grow more branches, the banyan can cover an area of around 10,000 metres, making a canopy of some 19,000 metres — this is the dimension of the world’s largest banyan tree in Anantapur district of Andhra Pradesh.

It was the British who gave this indigenous tree species its name ‘banyan’, for they would often see baniyas, traders, gather in its shade to conduct their business, write Nanditha Krishna and M Amrithalingam in Sacred Plants Of India.

Interestingly, the banyan was never high on the list of trees that horticulturists in the 1910s had made to line the avenues of the newly developed Lutyen’s Delhi. They thought it was ‘too overpowering’, ‘too big, too blocky’. The tree that is invoked by Hindus as the male consort of the peepul, seemed to them right only for large roundabouts, writes Pradip Kishen in Trees Of Delhi

But, it is because of these very reasons — its expanse and grand presence — that this evergreen, drought-resistant, long-lived tree, which is native to the Indian peninsula, has never gone out of public recall and can be spotted standing big and tall in parks or on roadsides, offering shade and succour to passersby.

“Trees give you life, a reason to be happy. The banyan just took root in me; it just grew on me. I find it very rejuvenating and so have been painting it for the last five years,” says Aparna. “There are many banyan trees in my city; there is a whole grove in the outskirts, in the Mhow Cantonment area, which is said to be more than 500 years old.”

The beauty of a tree is that you can look at the topmost part, its rustling leaves, and go down to the depths of its roots which have an infinite reach and see a being which nurtures, gives shelter and sustenance to so many forms of life around it. You are also looking at a tree that stands like a solitary sentinel, like all the greatest com-posers, philosophers, artists, and greatest individuals in the world, who have made solitary journeys.”

Did painting the banyan change Aparna’s perspective on trees? “Yes, now I observe them more keenly, how the light is falling on them, how more lyrical and beautiful they are becoming…,” says Aparna. She has begun to care for them.

I have now spotted a banyan right next to my office. Do I care what happens to it? I think I do. The tree, too, has begun to tell me how to just ‘be’. Standing amidst all the traffic and noise, it continues to look stately and calm, doing what comes to it naturally — give shade, oxygen, food and shelter to animals and birds around — a real mahayogi. The magic of the banyan is beginning to grow on me.

Rain bears a subtle link with all aspects of life. It serves as a powerful narrative tool in the poet’s life. It has added a layer of depth and fullness to the situation where the poet is concerned. It delivers an effective voice which communicates the apt moment of time and space as well as the emotions of the protagonist in a more poignant manner than mere words would do.

The role of Alluri Sitaram Raju in Andra Pradesh during the 1920s:

Alluri Sitarama Raju was an Indian rebellious who fight against the atrocities of British Raj. A tribal revolt was led by him against the exploitation of forest resources by Britishers which were important for tribal people for their survival. He led an armed revolt against the Britishers in the area of Madras Presidency. Finally, he was trapped in the jungle of Chintapalle and then executed.

Tyranny refers to dictatorial and opressive rule. 

Tamil Eelam is a proposed independent state that Tamils in Sri Lanka and the Sri Lankan Tamil diaspora aspire to create in the north and east of Sri Lanka. It has no official status or recognition by world states.
