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.

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.

Q10. Beyond what distance a normal eye can see objects clearly?
Q10. 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.

Q12. Why the sky appears blue?
Q12. Why the sky appears blue?
Answer: (C) Dispersion of light
Answer: (C) Dispersion of light
Answer: (C) Dispersion of light
Blue colour of the sky is due to dispersion or scattering of light. The two most common types of matter present in the atmosphere are gaseous nitrogen and oxygen. These particles are most effective in scattering the higher frequency and shorter wavelength portions of the visible light spectrum.
