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.

Q12. Identify the normally radioactive material in the following list.
Q12. 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

Answer: (C) Galileo Galilei
Answer: (C) Galileo Galilei
Answer: (C) Galileo Galilei
Galileo Galilei becomes the first to observe Saturn's rings with his 20-power telescope in 1610. He thought the rings were "handles" or large moons on either side of the planet.

Q14. What is the normal temperature of human body?
Q14. What is the normal temperature of human body?
Answer: (A) 37°C
Answer: (A) 37°C
Answer: (A) 37°C
Normal body temperature is considered to be 37°C (98.6°F); however, a wide variation is seen. Among normal individuals, mean daily temperature can differ by 0.5°C (0.9°F), and daily variations can be as much as 0.25 to 0.5°C.

Answer: (C) Crust
Answer: (C) Crust
Answer: (C) Crust
Crust
The structure of the Earth is divided into four major concentric layers: inner core, outer core, mantle and crust (the outermost layer). The crust is made up of tectonic plates, which are in constant motion.
