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.
Q1. Who discovered the Rings of Saturn?
Q1. Who discovered the Rings of Saturn?
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.

Q3. What is the lower fixed point of fahrenheit scale?
Q3. What is the lower fixed point of fahrenheit scale?
Answer: (B) 32°F
Answer: (B) 32°F
Answer: (B) 32°F
The lower fixed point in Fahrenheit scale is 32 degree and upper fixed point in Fahrenheit scale is 212 degree. The difference between the two is 180, hence number of division is 180.

Q7. What is the Distance between the Earth and the Moon?
Q7. What is the Distance between the Earth and the Moon?
Answer: (C) 384,400 KM
Answer: (C) 384,400 KM
Answer: (C) 384,400 KM
384,400 KM.
The average distance between Earth and the Moon is 384,400 kilometers (238,855 miles). This is about 30 times the diameter of Earth. The Moon’s orbit around Earth is elliptical, so the distance between the two bodies varies slightly.
The semi-major axis has a value of 384,399 km (238,854 mi). The time-averaged distance between the centers of Earth and the Moon is 385,000.6 km (239,228.3 mi). The actual distance varies over the course of the orbit of the Moon, from 356,500 km (221,500 mi) at the perigee to 406,700 km (252,700 mi) at apogee, resulting in a differential range of 50,200 km (31,200 mi).

Answer: (B) 149,597,870 KM
Answer: (B) 149,597,870 KM
Answer: (B) 149,597,870 KM
149,597,870 KM.
The Earth is at 147,100,000 km at perihelion and 152,000,000 km at aphelion.
The Astronomical Unit or AU is based on the average distance of the Earth from the Sun. The AU became a international standard in 2012 and is defined to be exactly 49,597,870.7 km.

Q11. 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.

Q20. Which is responsible for Earth's magnetic field?
Q20. 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.
