This question tests the fundamental understanding of scalar and vector quantities in physics. A scalar quantity has only magnitude, while a vector quantity has both magnitude and direction.
Correct Option: D) Velocity
Velocity is defined as the rate of change of displacement. Since displacement is a vector quantity (it has both magnitude and direction), velocity also has both magnitude and direction. For example, a car moving at \(60 \, \text{km/h}\) to the East has a velocity, where \(60 \, \text{km/h}\) is the magnitude and "East" is the direction.
The question asks to identify an example of chemical weathering. Chemical weathering involves the alteration of the chemical composition of rocks, leading to their breakdown. We need to evaluate each option to determine if it describes a chemical process.
D) Oxidation — Oxidation is a chemical process where minerals in rocks react with oxygen, leading to the formation of new compounds and the weakening of the rock structure. This directly alters the chemical composition of the rock, fitting the definition of chemical weathering.
The question asks about the proposed location of India's first Quantum Computing Village, specifically mentioning a state government meeting in April 2025 under the Real-Time Governance Society (RTGS). This requires knowledge of recent developments and proposals related to quantum computing initiatives in Indian states.
Correct Option: C) Amaravati, Andhra Pradesh
The Andhra Pradesh government, through its Real-Time Governance Society (RTGS), has indeed been proactive in proposing advanced technology hubs. The proposal for India's first Quantum Computing Village in Amaravati aligns with the state's vision for technological advancement and innovation. This initiative aims to foster research, development, and application of quantum computing technologies.
The question asks to identify the urban feature of Indus Valley cities that demonstrates advanced planning, specifically mentioning streets intersecting at right angles and covered drains. We need to evaluate each option based on historical knowledge of the Indus Valley Civilization.
Correct Option: A) Grid-pattern layout — The Indus Valley Civilization is renowned for its highly organized urban planning, with cities like Mohenjo-Daro and Harappa exhibiting a remarkable grid-pattern layout. Streets were laid out in a precise grid, intersecting at right angles, dividing the city into rectangular blocks. This systematic arrangement, combined with an elaborate system of covered drains and sanitation, is a clear indicator of advanced urban planning and engineering skills.
The question asks for the specific year of the Street Vendors (Protection of Livelihood and Regulation of Street Vending) Act, which is a prerequisite for States/UTs to implement the PM SVANidhi scheme. This requires knowledge of the relevant legislation.
C) 2014 — The Street Vendors (Protection of Livelihood and Regulation of Street Vending) Act was enacted in 2014. The PM SVANidhi scheme is available only in those States/UTs that have notified rules and a scheme under this specific Act.
The question asks to identify the correctly matched pair among the given options, considering both the abbreviation and its function in the context of computer hardware.
Correct Option: A) ROM – Read Only Memory – Stores boot instructions needed when the computer is powered on
The question asks to identify the state whose physiography is largely defined by the Indo-Gangetic Plain. This requires knowledge of the geographical distribution of major physiographic divisions of India, specifically the Indo-Gangetic Plain, and the states located within it.
Correct Option: B) Uttar Pradesh. Uttar Pradesh is almost entirely situated within the fertile Indo-Gangetic Plain, making its physiography largely defined by this geological feature. The state's flat topography, rich alluvial soil, and extensive river network are characteristic of the plain.
The question asks to identify the specific location where Aruna Asaf Ali hoisted the Indian National flag during the Quit India Movement in 1942. This requires knowledge of key events and figures associated with India's freedom struggle.
Correct Option: D) Gowalia Tank Maidan, Bombay
The question asks to identify the tribunal specifically established to handle service-related disputes of public servants. We need to evaluate each option based on its primary jurisdiction.
Correct Option: D) Central Administrative Tribunal
The Central Administrative Tribunal (CAT) was established under Article 323-A of the Constitution of India, specifically to adjudicate disputes and complaints with respect to recruitment and conditions of service of persons appointed to public services and posts in connection with the affairs of the Union. It provides a specialized forum for resolving service-related grievances of central government employees.
The ampere magnitude is determined by setting the numerical value of the elementary charge equal to _______ .
1.624432754 x 10-17 C
1.655908436 x 10-18 C
1.602176634 x 10-19 C
1.611547243 x 10-19 C
This question tests knowledge of the fundamental constants in physics, specifically the defined value of the elementary charge, which is crucial for the modern definition of the ampere.
The ampere, the SI unit of electric current, was historically defined based on the force between two current-carrying conductors. However, since May 20, 2019, the SI units, including the ampere, have been redefined based on fixed numerical values of fundamental physical constants.
According to the redefinition, the ampere is now defined by setting the numerical value of the elementary charge (\(e\)) to a fixed value when expressed in the unit coulomb (C). This means that one ampere is the current corresponding to the flow of \(1/(1.602176634 \times 10^{-19})\) elementary charges per second.
The exact fixed numerical value of the elementary charge, \(e\), adopted by the International Bureau of Weights and Measures (BIPM) for the redefinition of the SI base units, is \(1.602176634 \times 10^{-19}\) coulombs (C).
Therefore, to determine the ampere magnitude based on the elementary charge, this specific value is used.
C) The ampere magnitude is determined by setting the numerical value of the elementary charge equal to \(1.602176634 \times 10^{-19}\) C. This is the internationally accepted and defined value of the elementary charge as per the 2019 redefinition of SI units.
