Mandal Commission (led by B.P Mandal) was asked to determine the criteria to identify the Socially and Educationally Backward Classes (SEBC) and recommend the steps taken for their advancement. The Commission gave its report in 1980 and one of its recommendation was 27 percent of government job offers to be reserved for SEBC. In the Lok Sabha elections of 1989, Janata Dal promised to implement the Mandal Commission report if it won the elections and unsurprisingly it did. Several devolpments took place after that: • The President of India in his address to the Parliament announced the intention of implementation of the Mandal Commission • On 6th August 1990, the Union Cabinet took a formal decision to implement the recommendations. • The decisions of the Cabinet was sent to the Department of Personel and Training. The Senior Officers of the Department drafted an order.

I really think that the reservtion for OBC,SC and ST should be diminished so that WE the people of GENERAL CATEGORY feel relaxed. Everywhere we have to show 200% potential so that we could join a good Institute.....even for goverment services we have to suffer because OBC,SC and ST ko jaha sirf 80 marks chahiye waha GENERAL CATEGORY ko 90 marks laane hote hai (CTET) .

Side of square field = 20m Perimeter =20*4=80m Time=80sec Means she complete 1 lap in 80 second, therefore 2 laps in 160 sec then half in 40 seconds... So the displacement is the diagonal of square = root side Average velocity is eaual to total time taken upon total distance travelled = 200/200= 1m/s

The Nazis established control over its people by various means: → They used different propganda through posters or films to glorify their behaviour. → Media was carefully used to win support for the regime and popularise it. → Nazism worked on the minds of the people, tapped their emotions and turned their hatred and anger against those marked as ‘undesirable’. → Special surveillance and security forces to control and order society in ways that the Nazis wanted, was created. → The police forces had powers to rule with impunity. Genocide also created an atmosphere of fear and repression which helped them to establish total control over its people.

The aqueous solution of acid contain H+ ions and free ions/electrons are responsible for conducting electricity.And in aqueous state ions can moves freely to conduct electricity

0 Thank You

Jay Rakecha 4 years, 11 months ago (10760175)

Acids undergo dissociation in aqueous solution to form H+ ions. When electricity is passed through an aqueous solution of an acid, the H+ ions reach the cathode and each H+ ion picks up one electron from the cathode to form H2 gas. Because of this reaction, an aqueous solution of acid conducts electricity.

1 Thank You

Khushi 4 years, 11 months ago (9191743)

The aqueous solution of acid conduct electricity because the acid solution have H+ ions and the movement of these ions helps for the flow of electrical current through the solution.
