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.

Q5. Who was the first woman to win the Nobel Prize in Physics?
Q5. 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.

Q6. The speed of light is maximum in
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.

Q16. Beyond what distance a normal eye can see objects clearly?
Q16. 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.

Q18. Which is responsible for Earth's magnetic field?
Q18. Which is responsible for Earth's magnetic field?
Answer: (B) Outer Core
Answer: (B) Outer Core
Answer: (B) Outer Core
Outer Core
The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.
