Q72. Newton’s second law of motion establishes a relationship between which of the following physical quantities?
Explanation
Newton’s second law of motion quantifies how the motion of an object changes when an external force is applied. It establishes that the net force acting on a body is directly proportional to its mass and the resulting acceleration. This fundamental relationship is often expressed as force equals mass times acceleration, providing a critical framework for calculating the dynamics of physical systems.
Q73. Which of the following tool types is incorrectly associated with the Lower Palaeolithic culture of Rajasthan?
Explanation
The Lower Palaeolithic culture in Rajasthan is defined by heavy stone tools such as handaxes, cleavers, and choppers. These tools were typically made from coarse quartzite using hard hammer techniques. In contrast, geometric microliths are miniature stone tools characteristic of the much later Mesolithic period. Their presence indicates a significant technological shift toward hafting and specialized hunting equipment for small game species.
Q74. Which of the following is cited by scholars like M.R. Sahni and Robert Raikes as a primary physical cause for the decline of Mohenjo-daro?
Explanation
Scholars such as Robert Raikes and M.R. Sahni proposed that geological disturbances played a major role in the decline of the Indus Valley Civilisation. They argued that tectonic upliftment in the lower Indus valley caused the river to be impounded. This resulted in prolonged flooding that submerged Mohenjo-daro, eventually leading to the city’s slow abandonment by its many inhabitants.
Q75. Consider the following statements regarding the Constituent Assembly under the Cabinet Mission Plan:
I. The total strength of the Constituent Assembly was fixed at 389.
II. 296 seats were allotted to British India and 93 seats to the Princely States.
III. Out of 296 seats allotted to British India, 292 members were to be drawn from the eleven governors’ provinces.
IV. Four members were to be drawn from the four chief commissioners’ provinces, one from each.
Which of the above combination of statements is correct?
I. The total strength of the Constituent Assembly was fixed at 389.
II. 296 seats were allotted to British India and 93 seats to the Princely States.
III. Out of 296 seats allotted to British India, 292 members were to be drawn from the eleven governors’ provinces.
IV. Four members were to be drawn from the four chief commissioners’ provinces, one from each.
Which of the above combination of statements is correct?
Explanation
The total strength of the Constituent Assembly was fixed at 389 members under the Cabinet Mission Plan. This total included 296 seats for British India and 93 seats for the princely states. Of the British Indian seats, 292 were drawn from the eleven governors’ provinces, while the remaining four were allocated to the four chief commissioners’ provinces, one from each.
Q76. Which of the following pairs of volcanic mountains and their respective countries is correctly matched?
Explanation
Volcanic mountains are created by the accumulation of lava and pyroclastic materials. Mount Kilimanjaro is the highest peak in Africa, located in Tanzania. Mount Fuji is a famous volcanic cone in Japan, not Indonesia. Mount Vesuvius is located in Italy, while Mount Krakatoa is situated in Indonesia. Understanding these geographic locations is essential for studying global volcanic activity and landforms.
Q77. National Income is strictly equivalent to which of the following macroeconomic aggregates?
Explanation
National Income is technically defined as Net National Product at Factor Cost. It represents the total income earned by the factors of production belonging to a country. Unlike market price measures, it excludes indirect taxes and includes subsidies to reflect the actual costs of production. This aggregate serves as the most accurate indicator of the total economic value generated by citizens.
Q78. The recoil of a gun after firing a bullet is a practical illustration of:
Explanation
Newton’s third law states that for every action, there is an equal and opposite reaction. When a gun fires a bullet, it exerts a forward force on the projectile. Simultaneously, the bullet exerts an equal backward force on the gun. This reaction force causes the firearm to kick back or recoil, demonstrating the reciprocal nature of forces between interacting physical bodies.
Q79. Which of the following best explains the extensive Lower Palaeolithic habitation in the Didwana region despite its current semi-arid climate?
Explanation
Extensive Lower Palaeolithic habitation in the now semi-arid Didwana region was possible because environmental conditions were significantly different during the Pleistocene. Geological evidence suggests that the Thar desert experienced periods of higher rainfall and stable perennial water bodies. These conditions supported diverse flora and fauna, creating a hospitable environment for early human groups to thrive and manufacture various stone tool types.
Q80. The easternmost known site of the mature Indus Valley Civilisation, Alamgirpur, is located in the basin of which river?
Explanation
Alamgirpur, situated in the Meerut district of Uttar Pradesh, represents the easternmost boundary of the mature Harappan civilization. It is located in the basin of the Hindon River, which is a tributary of the Yamuna. The presence of this site demonstrates that the civilization’s influence extended significantly into the upper reaches of the Ganga-Yamuna Doab region during its peak.Answer key for these questions
