Category Description: Science is a rigorous, systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the world. Modern science is typically divided into three major branches: natural sciences (e.g., physics, chemistry, and biology), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study formal systems, governed by axioms and rules.

Q14. Beyond what distance a normal eye can see objects clearly?
Q14. Beyond what distance a normal eye can see objects clearly?
Answer: (C) 25 cm
Answer: (C) 25 cm
Answer: (C) 25 cm
For a clear vision, the image must be on the retina. The image distance is therefore fixed for clear vision and it equals the distance of retina from eye lens. It is about 25 cm for a grown up person. A person can theoretically have clear vision of an object situated at any large distance from the eye.

Q15. What is the scientific field dedicated to the study of heavenly bodies, celestial objects, and phenomena originating beyond Earth's atmosphere?
Q15. What is the scientific field dedicated to the study of heavenly bodies, celestial objects, and phenomena originating beyond Earth's atmosphere?
Answer: (D) Astronomy
Answer: (D) Astronomy
Answer: (D) Astronomy
Astronomy is a natural science that involves the scientific study of celestial objects (such as stars, planets, comets, galaxies, and nebulae), the universe as a whole, and the phenomena that originate beyond Earth's atmosphere. It uses principles of mathematics, physics, and chemistry to understand their origin, evolution, physical and chemical properties, and behavior. While cosmology is a branch of astronomy that focuses on the universe's origin, evolution, and large-scale structure, astronomy encompasses the broader study of all extraterrestrial objects and phenomena.

Answer: (D) Vaccum
Answer: (D) Vaccum
Answer: (D) Vaccum
The speed of light is maximum in a vacuum. Vacuum is the least dense medium with no obstruction to the path of light. Its refractive index is equal to unity, hence, the speed of light is maximum in a vacuum.

Q17. Who was the first woman to win the Nobel Prize in Physics?
Q17. Who was the first woman to win the Nobel Prize in Physics?
Answer: (A) Marie Curie
Answer: (A) Marie Curie
Answer: (A) Marie Curie
Marie Salomea Skłodowska–Curie
She was the first woman to win a Nobel Prize, the first person to win a Nobel Prize twice, and the only person to win a Nobel Prize in two scientific fields. Marie won her 1st Nobel Prize in 1903 in Physics with her husband for their pioneering work developing the theory of "radioactivity" - a term she coined. Marie won her 2nd Nobel Prize in 1911 in Chemistry for her discovery of the elements polonium and radium, using techniques she invented for isolating radioactive isotopes.
