Locust Plague:

A n s w e r :

A dense group of locusts is known as swarm. When these locusts swarms attack the crops and disturb agricultural economy, it is known as locust plague.

A circuit is said to be closed when every part of it is made of a conductor and on plugging in the key or on being complete, current flows through the circuit. The key in the closed circuit represented as (.)

A circuit is said to be open when no current flows through it. It can happen when the key is not plugged in or when any one of its components is not made of a conductor or when the circuit is broken. 

Sub: Requirement for Inter State Cricket Tournament.

Dear Sir,

We have an Inter-State Cricket Tournament the next month. We need some equipment for the same. Below is the required equipment.

1) 6 cricket balls

2) 4 cricket bats

3) 3 sets of wickets

4) 30 sets of safety guards and pads

5) 5 safety helmets.

Request you to please suggest the best suitable brands as always and please do revert with the availability and the price rates of the products.

Thanking you Sir.

Yours Sincerely,

A.P : 121, 117, 113...

a = 121

d =  117- 121= -4

Let an= 0

an = a + (n-1)d

⇒ 0 = 121 + (n-1)(-4)

⇒ 0 = 121 - 4n + 4

⇒4n = 125

⇒ n = 125/4

⇒ n = 31.25

n must be natural number therefore n= 32

Hence, 32nd term is first negative number.

Test for divisibility by 11. Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number.

So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.

Similarly, for 31415, the alternating sum of digits is 3 – 1 + 4 – 1 + 5 = 10. This is not divisible by 11, so neither is 31415.

By Euclid's division algorithm
b = aq + r,0 ≤ r < a [∵ dividend = divisor × quotient + remainder]
⇒ 117 = 65 × 1 + 52
⇒ 65 = 52 × 1 + 13
⇒ 52 = 13 × 4 + 0
∴ HCF (65,117) = 13             ...(i)     
Also, given that, HCF (65,117) = 65m - 117  ...(ii)
From Eqs.(i) and (ii),
65m - 117 = 13
⇒ 65m = 130
⇒ m = 2

1. Gautama Buddha went in search of enlightenment for about seven years before he finally came across a peepal tree and chose to sit under it till he became awakened.  When he finally attained salvation after 7 days, he decided to retitle the tree as the ‘Bodhi tree’ (which means the Tree of Wisdom) and he himself came to be known as ‘Buddha’ (which means The Awakened). 

2. Buddha preached in his sermons that everything that is born will come to its end. Death is inevitable: both young and adult or fools and wise are subject to death. But the people who do not grieve knowing the terms of the world are called wise people. Wise people neither weep nor grieve.

3. When he finally attained salvation after 7 days, he decided to retitle the tree as the ‘Bodhi tree’ (which means the Tree of Wisdom) and he himself came to be known as ‘Buddha’ (which means The Awakened).

4. Gautama Buddha began life as a prince named Siddhartha Gautama, in northern India. At 12, he was sent away for schooling in Hindu sacred scripture and 4 year later he returned home to marry a princess. They had a son and lived for 10 years as befitted royalty . At age of 25,the prince shielded from suffering of the world,while out hunting chanced upon a sick man,aged man,funeral procession and finally a monk begging for alms. these sights moved him that he lead to his enlightenment.

4. The Sermon at Benares throws light upon the early life of Lord Buddha who was originally born as a prince in the royal family. On being exposed to the sufferings of the world which he was earlier shielded from, he left his princehood and went in search of salvation thus leaving all the worldly pleasures behind. Upon attaining spiritual awakening, he gave his first sermon in the city of Benares hereby making a lady named Kisa Gotami realise that men are mortal and a wise person should not grieve at what is bound to happen for it only enhances pain and suffering.

Fundamental Theorem of Arithmetic:

Every composite number can be expressed (factorised ) as a product of primes, and this factorisation is unique, apart from the order in which the prime factors occur.

This theorem also says that the prime factorisation of a natural number is unique, except for the order of its factors.

For example 20 can be expressed as

2×2×5

Using this theorem the LCM and HCF of the given pair of positive integers can be calculated.

Snow rule states that if the current is flowing in an electric circuit from South to North direction

and magnetic compass is placed Over the conducting wire, the needle of the compass deflects in the West direction

The name of the rule is chosen so that to remeber the words :- S for South, N for north, O for over and W for West .

These letters are typed in bold letters in above statement.

Purpose of the rule is to find the direction of magnetic field produced by the current carrying conductor.

When current is flowing in the direction of south to north, magnetic field lines are circling around the conductor and the magnetic field directionabove the coductor  in the circular line is from east to west. Hence the field lines are such that as if a magnetic north pole is placed in the east. Hence the compass needle placed above the conductor shift towrads west.

It is Prudential Reason

Prudential Reasons: First, power sharing is good because it helps to reduce the possibility of conflict between social groups. Since, social conflict often leads to violence and political instability, power sharing is a good way to ensure the stability of political order. Imposing the will of majority community over minority community may look good in the short run but in the long run it undermines the unity of the nation.

Moral Reason: Power sharing is the very spirit of democracy. A democratic rule involves sharing power with those affected by its exercise, and who have to live with its effects. People have a right to be consulted on how they are to be governed. A legitimate government is one where citizens through participation acquire a stake in the system.

Lencho, a farmer, who is the protagonist of the story, writes a letter to God. In the letter, he seeks help from the Almighty as he discovers his entire crop yield has been destroyed by a devastating hailstorm. Although his wishes get fulfilled partially, if not completely, he remains ungrateful in the end.
