How the title is appropriate in the chapter A letter to God

Posted by Ambika Chowdhury 4 years, 8 months ago

CBSE > Class 10 > English Language and Literature

1 answers

Sia ? 4 years, 8 months ago

A letter to God’ is a story of extreme faith in god. The story is all about how a poor farmer wrote to God asking for money and a postmaster helped him instead.
When the farmer found that the money was less than he had asked for, he wrote to God again, asking for more but not to send it via post because they were thieves.
The title is justified because it is all about faith and how God works in strange ways. There is also a slight irony in the fact that a human helped out but the faith was so strong that the farmer continued to believe that it was God.

Show that root 2 is an irrational number.

Posted by Utaav Mehta 4 years, 8 months ago

CBSE > Class 10 > Mathematics

2 answers

Sia ? 4 years, 8 months ago

Let us assume that {tex}\sqrt2{/tex} is a rational number.
So it can be expressed in the form p/q where p, q are co-prime integers and q {tex}\ne{/tex} 0
{tex}\sqrt2{/tex} = p/q
Here p and q are coprime numbers and q {tex}\ne{/tex} 0
Solving
{tex}\sqrt2{/tex} = p/q
On squaring both the side we get,
{tex}\Rightarrow{/tex} 2 = (p/q)²
{tex}\Rightarrow{/tex} 2q² = p² .. (1)
p²/2 = q²
So 2 divides p and p is a multiple of 2.
{tex}\Rightarrow{/tex} p = 2m
{tex}\Rightarrow{/tex} p² = 4m² ..(2)
From equations (1) and (2), we get,
2q² = 4m²
{tex}\Rightarrow{/tex} q² = 2m²
{tex}\Rightarrow{/tex} q² is a multiple of 2
{tex}\Rightarrow{/tex} q is a multiple of 2
Hence, p, q have a common factor 2. This contradicts our assumption that they are co-primes. Therefore, p/q is not a rational number
{tex}\sqrt2{/tex} is an irrational number.

√5 is a irrational

Posted by Abhinav Jha 4 years, 8 months ago

CBSE > Class 10 > Mathematics

5 answers

Anuradha Chaudhary 4 years, 8 months ago

We prove by contradiction method. Let assume that √5 is rational. √5=p/q ---eq......1 P and q are co prime integer with common factor 1. Squaring both side equation 1 5=p²/q² :. q²=p²/5 eq...2 It means p² have factor 5 so p would also have sector 5. p=5x squaring both side p²=25x² Puting this value of p² in equation 2 q²=25x²/5 q²=5x² q²/5=x² This means q² have factor 5. But our assumption says p and q have common factor 1. So our assumption was wrong √5 is irrational number.

Mamta ... 4 years, 8 months ago

yes √ 5 is an irrational no.

1Thank You

Ayan Patel 4 years, 8 months ago

Let 5 be a rational number. then it must be in form of qp where, q=0 ( p and q are co-prime) 5=qp 5×q=p Suaring on both sides, 5q2=p2 --------------(1) p2 is divisible by 5. So, p is divisible by 5. p=5c Suaring on both sides, p2=25c2 --------------(2) Put p2 in eqn.(1) 5q2=25(c)2 q2=5c2 So, q is divisible by 5. . Thus p and q have a common factor of 5. So, there is a contradiction as per our assumption. We have assumed p and q are co-prime but here they a common factor of 5. The above statement contradicts our assumption. Therefore, 5 is an irrational number.

How equality before law is different from universal adult franchise? What do you mean destiny of the society

Posted by Ambika Chowdhury 4 years, 8 months ago

CBSE > Class 10 > Social Science

2 answers

Anuradha Chaudhary 4 years, 8 months ago

Equality before law means everyone should be treated in the same way And universal adult franchise allow everyone to vote so these are two different topics

1Thank You

Aziz Fatima 4 years, 8 months ago

During the 18th century, people were inspired by the ideas of nationalism and liberalism and demanded equality before the law. At the same time, the right to vote and to get elected was granted exclusively to the property owning men. The remaining men and women were classified as passive citizens. For example , Only under the Jacobins period, all adult men enjoyed right to vote in France. However the Napoleonic code went back to the limited suffrage, and reduced the women to the status of a minor-- subject to the authorities of fathers and husbands. However, the universal adult franchise means the right to vote for every person. In this way , equality before the law was different from universal adult franchise.
