1.
Archimedes invented the law of:
Correct Answer
C. Flotation
Explanation
Archimedes invented the law of flotation. This law states that an object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid it displaces. This principle explains why objects float or sink in a fluid, such as water. Archimedes discovered this law while trying to determine if a crown was made of pure gold. He realized that the crown displaced an equal volume of water when submerged, which led him to the principle of flotation.
2.
He is generally considered as the mathematician of:
Correct Answer
D. Antiquity
Explanation
The correct answer is "Antiquity" because the question is asking about the mathematician's era or time period. Antiquity refers to the ancient times or the period before the Middle Ages. Therefore, the mathematician is generally considered to have lived and worked during ancient times.
3.
Archimedes was born in:
Correct Answer
D. 287 BC
Explanation
Archimedes was born in 287 BC. This is because BC (Before Christ) dates count backwards, with the number getting smaller as we go further back in time. Therefore, 287 BC is an earlier date than 289 AD and both dates are BC (Before Christ), so 287 BC is the correct answer.
4.
One of these is not a field Archimedes was involved in:
Correct Answer
A. Biology
Explanation
Archimedes was a renowned mathematician, physicist, and astronomer, but there is no historical evidence or record of his involvement in the field of biology. His notable contributions were primarily in the areas of mathematics, physics, and astronomy. Therefore, the correct answer is Biology.
5.
Archimedes lived for how many years?
Correct Answer
D. 75 years
Explanation
Archimedes lived for 75 years. This is the correct answer because it directly corresponds to the question asking for the number of years he lived.
6.
A machine invented by Archimedes used for transferring water from a low-lying body of water into irrigation ditches is called?
Correct Answer
C. Hydraulic Screw
Explanation
The correct answer is Hydraulic Screw. The machine invented by Archimedes for transferring water from a low-lying body of water into irrigation ditches is called a hydraulic screw. This device consists of a large screw inside a cylinder that is turned by a handle. As the screw turns, it lifts water from a lower level to a higher level, allowing it to be transported to the irrigation ditches. This invention was a significant advancement in ancient engineering and played a crucial role in the development of irrigation systems.
7.
Archimedes died by:
Correct Answer
B. Murder
Explanation
The correct answer is murder. This means that Archimedes was intentionally killed by someone else. The options of suicide, assassination, and poisoning suggest that his death was not natural or accidental. Given the limited information provided, it is unclear who was responsible for the murder or the motive behind it.
8.
Archimedes discovered the Archimedes principle when he was:
Correct Answer
D. Taking his bath
Explanation
Archimedes discovered the Archimedes principle when he was taking his bath. This principle states that when an object is immersed in a fluid, it experiences an upward buoyant force equal to the weight of the fluid it displaces. According to the popular anecdote, Archimedes realized this principle while taking a bath and observing the water level rise as he entered the bathtub. He then made the connection between the water displacement and the buoyant force, leading to his famous exclamation "Eureka!" which means "I have found it" in Greek.
9.
Archimedes was well known as a:
Correct Answer
C. Mathematician
Explanation
Archimedes was well known as a mathematician because he made significant contributions to the field of mathematics. He developed the principles of geometry, including the calculation of pi and the concept of buoyancy. Archimedes also invented various mathematical tools and machines, such as the Archimedes screw and the compound pulley system. His mathematical achievements greatly influenced future mathematicians and scientists, making him renowned in the field of mathematics.

Where was Archimedes born?
Correct Answer
D. Syracuse
Explanation
Archimedes was born in Syracuse.
