Question 8

The 'Pothuvidyabhyasa Samrakshana Yanjam' (Public Education Rejuvenation Mission) is a flagship initiative of the Kerala government. Which of the following best describes its overarching objective?

Accepted Answer

C. To transform government schools into centers of excellence and bring back students from private institutions. — The Public Education Rejuvenation Mission's core aim is to enhance the quality and infrastructure of government schools, making them attractive alternatives to private schools. This initiative seeks to improve educational standards and increase enrollment by fostering public confidence in government institutions. Options A, B, and D represent either existing provisions, specific sub-components, or objectives not central to this particular mission's overarching goal.

Answer

A. To provide free education up to the university level for all students.

Answer

B. To establish new government schools in every panchayat across the state.

Answer

D. To introduce a uniform curriculum and grading system for all public and private schools.

Question 9

The proposed development of National Waterway 3 (NW3) in Kerala, running from Kollam to Kottapuram, is expected to significantly impact the state's logistics and economy. Beyond reducing road congestion, which of the following represents the MOST significant *environmental* advantage of promoting inland water transport over road transport for cargo movement?

Accepted Answer

A. Lower carbon emissions per ton-kilometer of freight. — Inland water transport is widely recognized for its superior energy efficiency compared to road transport, leading to significantly lower fuel consumption and, consequently, reduced carbon dioxide emissions per unit of freight moved. This makes it a crucial strategy in mitigating climate change impacts. While reduced noise pollution and less land acquisition are also benefits, the reduction in greenhouse gas emissions offers the most significant environmental advantage on a broader scale.

Answer

B. Reduced noise pollution in urban areas.

Answer

C. Preservation of biodiversity along riverine ecosystems.

Answer

D. Minimized land acquisition requirements compared to new highways.

Question 10

A monochromatic light source illuminates a metal surface, causing photoelectrons to be emitted. If the intensity of the light is doubled while keeping its frequency constant, what would be the observed change in the photoelectric current and the maximum kinetic energy of the emitted photoelectrons?

Accepted Answer

A. Photoelectric current doubles, maximum kinetic energy remains constant. — Doubling the intensity of light, while keeping its frequency constant, increases the number of photons incident on the metal surface per unit time. This leads to a proportional increase in the number of emitted photoelectrons, hence doubling the photoelectric current. However, the maximum kinetic energy of the emitted photoelectrons depends solely on the frequency of the incident light and the work function of the metal, remaining unaffected by changes in intensity.

Answer

B. Photoelectric current remains constant, maximum kinetic energy doubles.

Answer

C. Both photoelectric current and maximum kinetic energy double.

Answer

D. Both photoelectric current and maximum kinetic energy remain constant.
