RAS Prelims MCQ Practice

Explanation

Under Maharana Kumbha, Mewar checked the expansion of the Malwa and Gujarat sultanates, so Statement I is correct. Samarangana Sutradhara was written by Bhoja and Manasollasa by Someshvara III, not by Kumbha, so Statement II is incorrect.

Explanation

The Central Government has the power to remove the chairperson or members for reasons like insolvency or conviction. However, according to the principles of natural justice, no person can be removed from office unless they have been given a reasonable opportunity of being heard, ensuring that the removal process is fair and transparent. This legal safeguard prevents arbitrary dismissals and ensures that the members can carry out their duties without fear of sudden removal for political reasons. The requirement for a fair hearing upholds the rule of law and protects the institutional integrity of the commission as an independent protector of child rights.

Explanation

According to the Saha equation, increasing the temperature of a gas provides more energy for ionization, thereby increasing the degree of ionization. However, an increase in electron pressure actually drives the reaction in the opposite direction, promoting the recombination of ions and electrons into neutral atoms. Therefore, higher electron pressure leads to a lower degree of ionization in a stellar atmosphere.

Explanation

Vidyadhar Bhattacharya was the chief architect of Jaipur city, which he designed on a grid plan for Sawai Jai Singh II. He did not build the Vijay Stambh, Hawa Mahal or Kumbhalgarh.

Explanation

Kumbha built many forts, notably Kumbhalgarh, wrote works on music such as Sangita Raj and raised the Vijay Stambha at Chittorgarh. He did not ally with the Delhi Sultanate to defeat Gujarat, so III is incorrect.

Explanation

The Right to Education Act significantly expanded the commission’s mandate by designating it as the primary agency to monitor the implementation of free and compulsory education. It is empowered to examine and review the safeguards provided under the Act and to inquire into complaints regarding the violation of a child’s right to education. This monitoring role is crucial for the success of the RTE Act. By investigating complaints about school admissions, infrastructure, and quality of education, the commission ensures that the government and schools are held accountable, making the right to education a practical reality for millions of children across the country.

Explanation

The Saha equation is primarily used to understand the physical conditions of stellar surfaces. It is essential for spectral classification, determining photospheric temperatures, and analyzing the composition of the solar chromosphere. The Hubble constant, however, relates to the rate of expansion of the universe and large-scale cosmic distances, which is a field of cosmology independent of stellar ionization physics.

Explanation

The order of reign is Rana Hammir, Maharana Kumbha, Maharana Sanga and Maharana Pratap.

Explanation

During inquiries, the commission can summon individuals and enforce their attendance. It also has the power to forward cases to a Magistrate if the evidence suggests a criminal offense has been committed. However, it does not have the constitutional authority to strike down state laws, which is a power reserved for the judiciary. These powers allow the commission to function as an effective investigative body.

Explanation

Before Saha’s work, stellar spectroscopy was largely a tool for cataloging stars without understanding the underlying physics. His interpretation of spectral lines allowed scientists to calculate the actual temperature and pressure of stellar gases. This shift enabled astronomers to build physical models of stars, marking the birth of modern astrophysics where observations are linked to fundamental thermodynamic and atomic principles.
