Q) The term black hole was coined by ______.
A. C.V. Raman
B. S Chandrasekhar
C. John A. Wheeler
D. H.J. Bhabha
Answer: C. John A. Wheeler
Explanation: The term "black hole" was coined by American physicist John A. Wheeler in 1967. Wheeler is credited with popularizing the term, which refers to a region of spacetime where gravity is so strong that nothing, not even light, can escape from it. This concept emerged from the work of Albert Einstein and his theory of general relativity. While other scientists, including Karl Schwarzschild and Subrahmanyan Chandrasekhar, made significant contributions to the understanding of black holes, it was Wheeler who coined the term itself.
Q) The sound travels in the form of vibrations and has different speeds in different media. The speed of sound will be maximum in __________.
A. Sea water
B. Iron rod
C. Human blood
D. Dry air
Answer: B. Iron rod
Explanation: The speed of sound is influenced by the density and elasticity of the medium through which it travels. Generally, sound travels fastest in solids, followed by liquids, and slowest in gases. Iron, being a solid material, possesses high elasticity, resulting in the transmission of sound waves at a faster rate compared to liquids and gases. Therefore, in the given options, the speed of sound will be maximum in an iron rod.

Q) Read the following statements and select the correct option.
Statement 1: Planet Neptune appears blue.
Statement 2: The presence of methane gas in the atmosphere of Neptune is responsible for the blue colour.
A. Both statements 1 and 2 are correct and statement 2 is the correct explanation of statement 1.
B. Both statements 1 and 2 are correct but statement 2 is not the correct explanation of statement 1.
C. Statement 1 is correct and statement 2 is incorrect.
D. Both statements 1 and 2 are incorrect.
Answer: A. Both statements 1 and 2 are correct and statement 2 is the correct explanation of statement 1.
Explanation: Statement 1 is true as Neptune indeed appears blue. Statement 2 provides the correct explanation for the blue coloration of Neptune. Methane gas in Neptune's atmosphere absorbs red light while reflecting blue light, resulting in the planet's distinctive blue color. Therefore, both statements are correct, and statement 2 accurately explains why Neptune appears blue, making option A the correct choice.

Q) The least difference in the duration between day time and night time will be found in _________.
A. Kanyakumari
B. Ladakh
C. Srinagar
D. Bhopal
Answer: A. Kanyakumari
Explanation: Kanyakumari, situated at the southernmost tip of the Indian subcontinent, experiences minimal variation in the duration between day time and night time throughout the year. This is because of its proximity to the equator, where the length of daylight and darkness remains relatively constant throughout the year. As a result, Kanyakumari has the least difference in the duration between day time and night time compared to the other options provided.

Q) All gases occupy zero volume when the temperature is reduced to ______.
A. 100°C
B. 273°C
C. –273.15°C
D. 0°C
Answer: C. –273.15°C
Explanation: According to the Ideal Gas Law and the concept of absolute zero, all gases theoretically occupy zero volume when the temperature is reduced to –273.15°C, which is also known as absolute zero. At this temperature, the kinetic energy of gas particles theoretically reaches its minimum possible value, causing them to stop moving and occupy zero volume. This temperature is the basis for the Kelvin temperature scale, where 0 K represents absolute zero.
