https://doubtsolver.com/ask/649/write-a-debate-on-dynastic-takeover-in-political-parties?show=651#a651
<ul><li>Dynastic dispensation has overrun the body politic, edging out democracy and moral fibre in equal measure.</li><li>According to Article 1 of the Constitution of India, “India, that is Bharat, shall be a Union of States”. The framers of our Constitution could have never imagined that India would slide back to a “Union of Princely States”.</li><li>According to Wikipedia, just before Partition, India was an amalgamation of 567 princely states under British rule. For more than 60 years, since Independence, our government has been the fiefdom of one family. Now, the States are slowly but surely sliding back to becoming fiefdoms of political dynasties.</li><li>From Kanyakumari to Kashmir, politics at the State level is dominated by powerful families. </li><li><strong>In Tamil Nadu</strong>, the baton is about to be handed over to Stalin, son of M Karunanidhi who was chief minister of the State for about 20 years. </li><li><strong>Telangana</strong> is certain to remain the fiefdom of K Chandrashekar Rao’s family for many years to come. His son and daughter are already minister and Member of Parliament respectively; and many members of the extended family hold similar positions. </li><li>The family of NT Rama Rao and YS Rajashekar Reddy dominate politics in erstwhile <strong>Andhra Pradesh</strong>. </li><li>Former prime minister HD Deve Gowda’s family is a force to reckon with in <strong>Karnataka</strong> with the newest entrant to politics being his daughter-in-law who, if not for reservation, would have been conferred president of a zilla panchayat.</li></ul><p><strong>It leads bad to worse</strong></p><ul><li>If it is bad enough in south India, it is a lot worse in the north with both the ruling and opposition parties dominated by dynasties.</li><li><strong>In Kashmir,</strong> the Abduallahs and the Muftis are the dominant force. Soon after the death of Chief Minister Mufti Mohammed Sayeed, the People Democratic Party did not even make a pretence of following democratic processes before handing over the reins to his daughter.</li><li><strong>In Punjab</strong>, the ruling Akali Dal and opposition Congress are dominated by two families. </li><li><strong>In Rajasthan</strong>, the current chief minister is grooming her son to take over the reins of the State. </li><li>And in <strong>Maharashtra</strong>, Pawars and the Thackareys will be a force to reckon with for the foreseeable future. As Amit Shah, president of the BJP, put it succinctly after the 2014 parliamentary election, in Uttar Pradesh, the “seats lost by the BJP and its allies were all won by parivars”.</li><li>The Nehru family is still a dominant force in the State with the bahus and grandchildren of his daughter being <strong>MP</strong>s. Mulayam Singh who anointed his son as chief minister after the last Assembly election, has his bahu and brothers backing him in Parliament. </li><li><strong>In Bihar</strong>, when Lalu Prasad Yadav had to demit office, he did not think twice before handing over the reins to his wife. After the spectacular comeback of his party, two of his sons are ministers and one of them can be safely deemed to be chief minister in waiting. And in Assam, the ex-chief minister is grooming his son who is already an MP, to be the numero uno in the State.</li></ul><p><strong>Creation of fatal flaws</strong></p><ul><li>At the heart of dynastic politics in India, are two fatal flaws — <em><strong>corruption</strong></em> and <em><strong>patronage</strong></em>. The rewards of political office offer much higher returns than occupying the C-suite in corporate India. In the post-liberalisation era, all things government — land, spectrum, mining rights, government contracts — were highly sought after and hence the reward for awarding rights and contracts fetched immense returns to those who occupied political office. As Tarun Das, former head of CII was heard saying on the infamous Radia Tapes, “a minimum of 15 per cent was skimmed” from contracts. Thus in the era of liberalisation there have been more rags to riches story in politics than in business.</li><li>Patronage too has been highly rewarding in Indian democracy. Party high commands act as patrons and hence it pays to be subservient to party bosses. From distribution of tickets in various elections to Rajya Sabha and Vidhan Parishad seats, favours are doled out by political parties to supreme loyalists. And parties occupying the corridors of power in State Assemblies and at the Centre have much more to offer — governorship of States, board Chairmen, directorship in PSUs, and heads of various government institutions.</li><li>To improve governance, our Prime Minister recently mooted simultaneous election to Parliament and the State Assemblies. But the problem in Indian democracy is not about year-round elections. Patronage politics, family-owned political parties and corrupt means of acquiring government assets are much more troubling. While economic reforms and better governance can reduce corruption, political reforms are sine qua non for ending patronage politics. In the long-term interest of the country, Modi and the Government must join hands with the Election Commission to reform politics too</li></ul><p><em>[via: brainly.in]</em></p>https://doubtsolver.com/ask/649/write-a-debate-on-dynastic-takeover-in-political-parties?show=651#a651Mon, 24 Jun 2019 12:11:41 +0000Answered: Who is primeminister of India?

<ul><li>The circumstances which led to the outbreak of revolutionary protest in France were a combination of social, economic, political and Intellectual circumstances.</li><li>These are discussed below <ul><li><strong>Social:</strong> The social order consisted of many inequalities. The privileged classes were the clergy and noblemen, the First and Second Estate respectively. They were exempt from paying taxes. The rest of the citizens belonged to the Third Estate and constituted the majority of the population.They did not have any political rights or social status, but paid all the taxes. So, they were very discontented.</li><li><strong>Economic:</strong> There was a financial crisis as the king's treasury was empty, The king's luxurious style of living and involvement in wars had made France very poor. There was no money to feed the poor when there was a bad crop.</li><li><strong>Political:</strong> The king ruled like an autocrat and the people had no voice in any decisions. The Estates General (French Parliament) had not been convened for many years. The administration was inefficient, corrupt and disorganized.</li><li><strong>Intellectual:</strong> At that time a number of philosophers refuted the theory of the divine right of kings to rule.

https://doubtsolver.com/ask/619/prove-that-root-over2-is-irrational?show=641#a641
<p>Let's suppose √2 is a rational number. Then we can write it √2 = a/b where a, b are whole numbers, b not zero.</p><p>We additionally assume that this a/b is simplified to lowest terms, since that can obviously be done with any fraction. Notice that in order for a/b to be in simplest terms, both of a and b cannot be even. One or both must be odd. Otherwise, we could simplify a/b further.</p><p>From the equality √2 = a/b it follows that 2 = a<sup>2</sup>/b<sup>2</sup>, or a<sup>2</sup> = 2 · b<sup>2</sup>. So the square of a is an even number since it is two times something.</p><p>From this we know that a itself is also an even number. Why? Because it can't be odd; if a itself was odd, then a · a would be odd too. Odd number times odd number is always odd. Check it if you don't believe me!</p><p>Okay, if a itself is an even number, then a is 2 times some other whole number. In symbols, a = 2k where k is this other number. We don't need to know what k is; it won't matter. Soon comes the contradiction.</p><p>If we substitute a = 2k into the original equation 2 = a<sup>2</sup>/b<sup>2</sup>, this is what we get:</p><p>2 = (2k)<sup>2</sup>/b<sup>2</sup></p><p>2 = 4k<sup>2</sup>/b<sup>2</sup></p><p>2*b<sup>2</sup> = 4k<sup>2</sup></p><p>b<sup>2</sup> = 2k<sup>2</sup></p><p>This means that b<sup>2</sup> is even, from which follows again that b itself is even. And that is a contradiction!!!</p><p><strong>WHY is that a contradiction?</strong></p><p>Because we started the whole process assuming that a/b was simplified to lowest terms, and now it turns out that a and b both would be even. We ended at a contradiction; thus our original assumption (that √2 is rational) is not correct. <strong>Therefore √2 cannot be rational.</strong></p><p><em>[based on solution given on homeschoolmath.net] </em></p>https://doubtsolver.com/ask/619/prove-that-root-over2-is-irrational?show=641#a641Sun, 23 Jun 2019 09:37:23 +0000Answered: Why dc current is not used in transformer

SI=160<br />

TIME=2 YEAR<br />
<br />
CI=164<br />
<br />
So,<br />
<br />
SI= PRT/100<br />
<br />
160=PR*2/100<br />
<br />
PR=8000...........(i equation)<br />
<br />
NEXT<br />
<br />
CI=P(1+R/100)^2-P<br />
<br />
TAKE P COMMON<br />
<br />
164=P((1+R/100)^2-1)........(ii equation)<br />
<br />
Divide first equation by second equation<br />
<br />
8000/164=(PR)/P((1+R/100)^2-1)<br />
<br />
2000/41=R/(1+R/100)^2-1<br />
<br />
CROSS MULTIPLICATION<br />
<br />
2000*{(1+R/100)^2-1}= 41R<br />
<br />
Open bracket<br />
<br />
2000*(1+R^2/10000+2R/100-1)=41R<br />
<br />
Gives<br />
<br />
2000*(R^2/10000+2R/100)=41R<br />
<br />
(R^2)/5+40R= 41R<br />
<br />
Cancel one R<br />
<br />
(R/5)+40=41<br />

(a^3-b^3)=(a-b)(a^2+ab+b^2)<br />
<br />
Here a=55, b=25<br />
<br />
55^3-25^3=(55-25)(55^2+55*25+25^2)<br />
<br />

<br />
Now <br />
<br />
55^3-25^3-30^3=30*5025-30^3<br />
<br />
Take 30 common<br />

https://doubtsolver.com/ask/305/if-one-the-zeros-bx-cx-is-the-product-of-then-other-two-zeroes-is?show=551#a551
If X is one of the zero of the equation then<br />
<br />
a*0^3+ b*0^2+c*0+d=0<br />
<br />
(X=0)<br />
<br />
Gives d=0<br />
<br />
So our final equation is<br />
<br />
ax^3+bx^2+cx=0<br />
<br />
Take X common and transpose it<br />
<br />
X(ax^2+bx+c)=0<br />
<br />
ax^2+bx+c=0<br />
<br />
Now sum of the roots will be equal to -b/a<br />

<p>Most time it linked either to misconfigured .htaccess or the defective plugin. The solution is based on <em><strong>trial and erro</strong></em>r method. First, do <em><strong>backup/copy</strong></em> of .htaccess file located to the folder where WordPress site installed. In most case, it's <em><strong>Public_html</strong></em>. If you are not sure about the accuracy of code in .htaccess then temporarily replace it with WordPress's native .htaccess script (see below code).</p><pre># BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress</pre><p>Now try to access the site. If it still keeps diverting toward 127.0.0.1 page then you need to follow the next step.</p><p>Navigate to cPanel or FTP browser and open plugin folder. Normally, located to<em> <strong>public_html/wp-content/plugins. </strong></em>Now find out folders belong to security plugins. Like <em>All in One security, WordFence</em>, etc. Rename the folder one by one with any different name as part of a trial and error method. Remember, in most case, renaming merely All in One Security folder solves the problem. As historically this error linked to All in One WordPress Security Plugin.</p><p>Hope it will help to solve your problem. Once the website started functioning correctly then you can clean the plugin folder. If you believe the plugin is still held importance and want to reinstall then backup everything (folder+database) after that you can install that plugin again.</p>https://doubtsolver.com/ask/538/wordpress-site-127-0-0-1-redirect-on-all-pages?show=539#a539Wed, 06 Mar 2019 13:51:09 +0000The angular speed of a flywheel is 3×22÷7 rad/sec .

https://doubtsolver.com/ask/491/what-leads-to-mutation?show=500#a500
<p><strong>The causes of mutations: </strong>Mutations happen for several reasons.</p><p><img alt="DNA Mutation" src="https://doubtsolver.com/ask/?qa=blob&qa_blobid=9065874087749883011" style="height:180px; width:389px"></p><p><strong>1. DNA fails to copy accurately</strong></p><p>Most of the mutations that we think matter to evolution are "naturally-occurring."<br><em><strong>For example</strong></em>, when a cell divides, it makes a copy of its DNA — and sometimes the copy is not quite perfect. That small difference from the original DNA sequence is a mutation.</p><p><strong>2. External influences can create mutations</strong></p><p>Radioactive signMutations can also be caused by exposure to specific chemicals or radiation. These agents cause the DNA to break down. This is not necessarily unnatural — even in the most isolated and pristine environments, DNA breaks down. Nevertheless, when the cell repairs the DNA, it might not do a perfect job of the repair. So the cell would end up with DNA slightly different than the original DNA and hence, a mutation.</p><p>[Source: <a target="_blank" rel="nofollow" href="https://evolution.berkeley.edu/evolibrary/article/evo_20">Berkeley</a>]</p>https://doubtsolver.com/ask/491/what-leads-to-mutation?show=500#a500Thu, 24 Jan 2019 14:24:20 +0000Answered: The enthalpy change on freezing of 1 mole of water at 5 °C to ice at -5 °C

<ul><li>When the object is removed, the volume that the object occupied will fill with fluid.</li><li>This volume of fluid must be supported by the pressure of the surrounding liquid since fluid cannot support itself.</li><li>When no object is present, the net upward force on this volume of fluid must equal to its weight, i.e. the weight of the fluid displaced.</li><li>When the object is present, this same upward force will act on the object.</li></ul><p> </p><p><a href="https://www.youtube.com/watch?v=2fCVMhCOGWE" rel="nofollow" target="_blank">https://www.youtube.com/watch?v=2fCVMhCOGWE</a><br><br>More info on <a href="https://physics.tutorvista.com/fluid-dynamics/buoyancy.html" rel="nofollow" target="_blank">https://physics.tutorvista.com/fluid-dynamics/buoyancy.html</a></p>https://doubtsolver.com/ask/487/what-is-buoyant-force?show=488#a488Mon, 07 Jan 2019 08:50:05 +0000Answered: What do you understand by lateral inversion and reflection of light
https://doubtsolver.com/ask/480/what-you-understand-lateral-inversion-and-reflection-light?show=481#a481
<p><strong>Lateral inversion </strong>means the apparent reversal of the mirror image's left and right when compared with the object. <em><strong>Lateral </strong></em>just means <em><strong>sideways</strong></em>. ... In a plane mirror, each point on the image is as far behind the mirror plane as the corresponding point on the object is in front.</p><p><a href="https://www.youtube.com/watch?v=BHarXghWrIQ" rel="nofollow" target="_blank">https://www.youtube.com/watch?v=BHarXghWrIQ</a></p>https://doubtsolver.com/ask/480/what-you-understand-lateral-inversion-and-reflection-light?show=481#a481Sat, 29 Dec 2018 11:18:45 +0000Magnification power if the ultimate reflection is in the infinity of a plain microscope
