The question asks about the initial constitution year of the National Disaster Management Authority (NDMA) by an executive order. This requires knowledge of the historical timeline of disaster management in India.
Correct Option: A) The National Disaster Management Authority (NDMA) was initially constituted on May 30, 2005, by an executive order, with the Prime Minister of India as its Chairperson. This was a crucial step towards a more structured approach to disaster management in the country.
The question asks to identify the title of a 2025 book by Pankaj Mishra that focuses on Middle Eastern conflicts within a global context. This requires specific knowledge about upcoming literary works by prominent authors.
Correct Option: C) The World After Gaza
The luminous efficacy of monochromatic radiation of frequency 540×1012 Hz, Kcd, is to be ____ when expressed in the unit lumen per watt.
The question asks for the luminous efficacy of monochromatic radiation with a specific frequency, expressed in lumens per watt. This value is a standard constant in photometry, representing the maximum luminous efficacy for a given frequency, which corresponds to green light at 555 nm (or approximately 540 THz).
Identify the given frequency: The frequency of the monochromatic radiation is given as \(540 \times 10^{12}\) Hz, which is \(540\) THz.
Relate frequency to wavelength: The speed of light (\(c\)), frequency (\(\nu\)), and wavelength (\(\lambda\)) are related by the formula \(c = \nu \lambda\). We can calculate the wavelength:
\[ \lambda = \frac{c}{\nu} \]Using the speed of light \(c \approx 3 \times 10^8 \text{ m/s}\):
\[ \lambda = \frac{3 \times 10^8 \text{ m/s}}{540 \times 10^{12} \text{ Hz}} \approx 5.555 \times 10^{-7} \text{ m} \]Converting this to nanometers (nm):
\[ \lambda \approx 5.555 \times 10^{-7} \text{ m} \times \frac{10^9 \text{ nm}}{1 \text{ m}} \approx 555.5 \text{ nm} \]Recognize the significance of the wavelength: A wavelength of approximately 555 nm corresponds to green light, which is the wavelength at which the human eye is most sensitive under photopic (daylight) conditions. The luminous efficacy at this peak sensitivity is defined as the maximum possible luminous efficacy.
Recall the standard value for peak luminous efficacy: The maximum luminous efficacy for monochromatic radiation at 555 nm (or 540 THz) is a defined constant. According to the International System of Units (SI), the candela is defined such that the luminous efficacy of monochromatic radiation of frequency \(540 \times 10^{12}\) Hz is exactly 683 lumens per watt.
D) 683 is the correct value for the luminous efficacy of monochromatic radiation of frequency \(540 \times 10^{12}\) Hz (555 nm) when expressed in lumens per watt. This is the peak luminous efficacy of the human eye under photopic conditions, a fundamental constant in photometry.
The question asks for the specific year when Burhan-ul-Mulk was appointed as the Nazim of Awadh. This requires knowledge of historical facts related to the Mughal Empire and the rise of autonomous regional states in the 18th century.
Correct Option: D) 1722. Burhan-ul-Mulk (Saadat Ali Khan I) was appointed the Nazim (governor) of Awadh in 1722. This appointment marked the beginning of the autonomous state of Awadh, which he established by gradually asserting his independence from the weakening Mughal central authority.
The question asks to identify the correct statement about the Council of Ministers. To answer this, we need to understand the composition and hierarchy within the Council of Ministers in the Indian parliamentary system.
Based on this understanding, let's evaluate the given options.
Correct Option: B) Cabinet Ministers are a smaller group within the Council of Ministers.
This statement is correct. The Council of Ministers is a broad body, and the Cabinet is a core, smaller group of senior ministers who are part of the Council of Ministers.
The question asks about a specific body established by Pitt's India Act of 1784. To answer this, we need to recall the key provisions and administrative changes introduced by this significant Act in British India's history.
Correct Option: C) The Pitt's India Act of 1784 established the Board of Control in Britain. This six-member body was tasked with supervising and directing all operations of the civil and military government or revenues of the British possessions in India. This marked the beginning of the British government's direct control over Indian administration, effectively creating a system of dual government where the Company retained commercial functions, and the Board of Control handled political and administrative functions.
This question tests knowledge about the basic elemental composition of proteins. Proteins are complex macromolecules essential for life, built from amino acids. Understanding the common elements found in organic molecules, especially biological ones, is key.
Correct Option: B) Phosphorus
The question asks about the primary crops that saw increased production during the Green Revolution in India. This requires knowledge of the historical context and agricultural focus of the Green Revolution.
Correct Option: C) Wheat and Rice — The Green Revolution primarily focused on and achieved significant increases in the production of wheat and rice through the introduction of High-Yielding Varieties (HYVs) of seeds, along with better irrigation, fertilizers, and pesticides.
The primary cause for the rise of Jainism and Buddhism was the religious unrest in India in the ______.
6th century BCE
5th century BCE
4th century BCE
7th century BCE
The question asks for the primary period when Jainism and Buddhism emerged due to religious unrest in India. This requires knowledge of the historical timeline of ancient Indian religions and the social/religious conditions that led to the rise of these new faiths.
Correct Option: A) The 6th century BCE is widely recognized as the period when both Jainism and Buddhism emerged as significant religious movements in India, driven by the prevailing religious and social conditions of the time.
The question asks to identify a potential disadvantage of globalisation for developing economies. We need to evaluate each option to determine if it represents a negative outcome.
Correct Option: C) Unequal income distribution
