Question 3

A school principal wants to implement a system where students' progress is continuously monitored through various methods like projects, presentations, and observations, rather than just a single annual exam. Which principle of NCF 2005 would most strongly support this initiative?

Accepted Answer

D. Making examinations more flexible and integrated with classroom life. — NCF 2005 advocates for making examinations more flexible and integrated into classroom life, moving away from high-stakes, year-end exams to continuous and comprehensive evaluation. This principle directly supports a system of varied assessment methods for ongoing student progress monitoring, rather than relying solely on a single annual exam.

Answer

A. Connecting knowledge to life outside the school.

Answer

B. Ensuring that learning shifts away from rote methods.

Answer

C. Enriching the curriculum so that it goes beyond textbooks.

Question 4

A worker pushes a heavy crate across a horizontal floor at a constant speed. The worker applies a constant force 'F' over a distance 'd'. Which of the following statements accurately describes the energy transformations and work done in this scenario?

Accepted Answer

B. The work done by the worker is Fd, and the work done by friction converts mechanical energy into heat. — Since the crate moves at a constant speed, its kinetic energy remains unchanged, meaning the net work done on it is zero according to the Work-Energy Theorem. The worker does positive work (Fd), and this work is entirely balanced by the negative work done by friction (-Fd), which converts the mechanical energy into thermal energy (heat). Therefore, option B is correct. Option A is incorrect because net work is zero and kinetic energy is constant. Option C is incorrect because mechanical energy is not conserved due to the presence of friction. Option D is incorrect because the work done is diss

Answer

A. The net work done on the crate is Fd, and its kinetic energy increases.

Answer

C. The total mechanical energy of the crate remains constant, as it moves at a constant speed.

Answer

D. The work done by the worker is entirely converted into the kinetic energy of the crate.

Question 9

NEP 2020 proposes significant reforms in the assessment system, moving towards a holistic, 360-degree assessment of student progress. Which of the following national initiatives has been established to set norms, standards, and guidelines for student assessment and evaluation, as adopted by SCERT Kerala?

Accepted Answer

D. PARAKH (Performance Assessment, Review, and Analysis of Knowledge for Holistic Development) — PARAKH (Performance Assessment, Review, and Analysis of Knowledge for Holistic Development) is the national assessment centre established under NEP 2020.
