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.

Q7. The weight of an object on the moon is equal to ___ of its weight on the earth.
Answer: (D) 1/6
Answer: (D) 1/6
Answer: (D) 1/6
1/6th
The moon's gravitational force is only about 16.6 % of Earth's gravity which means an object would weigh six times less on the moon than they do on Earth.

Q11. 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.

Q15. Identify the normally radioactive material in the following list.
Q15. Identify the normally radioactive material in the following list.
Answer: (A) Plutonium
Answer: (A) Plutonium
Answer: (A) Plutonium
Plutonium is the only radioactive element in the list.
Plutonium is a radioactive, silvery-gray, metallic element with the symbol Pu and atomic number 94. It has a high surface tension and viscosity compared to other metals, and tarnishes when exposed to air. Plutonium is created in a reactor when uranium atoms absorb neutrons, and is a by-product of nuclear power plants. It is the main fuel in fast neutron reactors, and more than one-third of the energy produced in most nuclear power plants comes from plutonium. Plutonium has five common isotopes, each with a different half-life, which is the time it takes to lose half of its radioactivity
