1.
Where was Archimedes born?
Correct Answer
A. Syracuse, Greece
Explanation
Archimedes was born in Syracuse, Greece. This is a historical fact that is widely known and documented. Syracuse was an ancient Greek city located on the eastern coast of Sicily, which was a part of Greece during Archimedes' time. He was a renowned mathematician, physicist, engineer, and inventor who made significant contributions to various fields of science and mathematics.
2.
Where did Archimedes die?
Correct Answer
B. Syracuse, Greece. He was killed by a Roman soldier.
Explanation
Archimedes died in Syracuse, Greece, as he was killed by a Roman soldier.
3.
When did Archimedes discover buoyancy?
Correct Answer
B. While taking a bath.
Explanation
Archimedes discovered buoyancy while taking a bath. This is because while he was in the bath, he noticed the water level rising and realized that the upward force exerted by the water was equal to the weight of the water displaced by his body. This led him to the principle of buoyancy, which states that an object immersed in a fluid experiences an upward force equal to the weight of the fluid it displaces.
4.
Which is NOT an example of one of his contributions?
Correct Answer
C. Airplane
Explanation
The question asks for an example of something that is NOT one of his contributions. The options given are Submarine, Hot Air Balloon, and Airplane. The correct answer is Airplane because it is not one of his contributions. This suggests that the person being referred to in the question has made contributions in the fields of Submarine and Hot Air Balloon, but not in the field of Airplane.

"The Archimedes Principle" states that:
Correct Answer
B. When an object floats into the fluid, it displaces the fluids of its own weight.
Explanation
The correct answer is: When an object floats into the fluid, it displaces the fluids of its own weight.
This answer accurately describes the Archimedes Principle, which states that the buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. When an object floats, it displaces an amount of fluid equal to its own weight, resulting in a balance between the upward buoyant force and the downward force of gravity. This principle explains why objects that are less dense than the fluid they are placed in will float.
6.
Which equation can be used to find the buoyant force?
Correct Answer
A. The apparent weight of the object = The original weight – the buoyant force exerted.
Explanation
The equation "The apparent weight of the object = The original weight – the buoyant force exerted" can be used to find the buoyant force. This equation states that the apparent weight of an object (the weight it seems to have when submerged in a fluid) is equal to the original weight of the object minus the buoyant force exerted on it by the fluid. This equation is derived from Archimedes' principle, which states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.
7.
Fishes are examples of the Archimedes Principle.
Correct Answer
A. True
Explanation
The statement is true because the Archimedes Principle states that an object immersed in a fluid experiences an upward buoyant force equal to the weight of the fluid it displaces. Fishes are able to float and swim in water due to this principle, as their bodies are less dense than water, causing them to experience an upward buoyant force that allows them to stay afloat. Therefore, fishes are indeed examples of the Archimedes Principle.
8.
Buoyancy is:
Correct Answer
A. The weight of the fluid displaced by the object.
Explanation
Buoyancy refers to the upward force exerted on an object submerged in a fluid, which is equal to the weight of the fluid displaced by the object. This force allows objects to float or sink in a fluid based on their density. It is a fundamental principle in physics and is used to explain various phenomena, such as why ships float and why helium balloons rise in the air.
9.
Archimedes had his formal education in:
Correct Answer
A. Alexandria, Egypt
Explanation
Archimedes had his formal education in Alexandria, Egypt. Alexandria was a renowned center of learning and knowledge during that time, attracting scholars from various parts of the world. Archimedes likely studied under the guidance of prominent mathematicians and philosophers in Alexandria, which contributed to his later achievements and discoveries in mathematics, physics, and engineering.
10.
The Archimedes's Claw was Archimedes's greatest invention.
Correct Answer
B. False
Explanation
The Archimedes's Screw was Archimedes's greatest invention.
