What is a "White Hole"
Correct Answer
B. A zone where in which matter is spontaneously created.
Explanation
A "White Hole" is a hypothetical region in space where matter is believed to be spontaneously created. It is the opposite of a black hole, which is a region where matter is consumed. While black holes have intense gravitational forces that do not let anything escape, white holes are thought to have the opposite effect, expelling matter and energy outward. However, it is important to note that white holes are purely theoretical and have not been observed or confirmed by scientific evidence.

Which fundemental law of physics does Robert Fludd's hypothetical "Perpetual Motion Machine" not follow?
Correct Answer
A. Thermodynamics
Explanation
Robert Fludd's hypothetical "Perpetual Motion Machine" does not follow the fundamental law of thermodynamics. The law of thermodynamics states that energy cannot be created or destroyed in an isolated system, and the perpetual motion machine violates this principle by suggesting a machine that can continuously generate energy without any external input or loss of energy.
3.
Which of Albert Einstein's famous theories is logically unsound?
Correct Answer
A. Theory of Special Relativity
Explanation
The Theory of Special Relativity is logically unsound because it contradicts some fundamental principles of physics, such as the conservation of energy and the existence of a universal reference frame. This theory suggests that the laws of physics are the same for all observers in uniform motion, regardless of their relative velocities. However, this contradicts the principle of conservation of energy, as it implies that energy can be created or destroyed. Additionally, the theory does not account for the existence of a universal reference frame, which is inconsistent with the principle that there should be a fixed point of reference in the universe.

___________ is best known for first defining gravity.
Correct Answer
Sir Isaac Newton
Isaac Newton
Newton
Explanation
Sir Isaac Newton is best known for first defining gravity. He is a renowned physicist and mathematician who formulated the laws of motion and universal gravitation. Newton's groundbreaking work in the late 17th century revolutionized our understanding of the physical world and laid the foundation for modern physics. His famous law of universal gravitation states that every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Newton's contributions to the field of gravity have had a profound impact on scientific knowledge and continue to be influential today.
5.
Why are our planet's orbits elliptical, and not round?
Correct Answer
B. Gravity tugs at them as they approach the sun, altering orbit.
Explanation
As objects approach the sun, gravity pulls on them, causing their orbits to be altered. This gravitational force is stronger when the objects are closer to the sun, which results in a more elliptical orbit rather than a perfectly round one.
6.
__________ first discovered Buoyancy.(Hint: Two of the names are made up)
Correct Answer
B. Archimedes
Explanation
Archimedes is credited with first discovering buoyancy. He was a Greek mathematician, physicist, engineer, inventor, and astronomer who lived in the 3rd century BC. Archimedes' principle, which explains the buoyant force acting on an object submerged in a fluid, is named after him. He made significant contributions to the understanding of buoyancy and hydrostatics, and his experiments and mathematical proofs laid the foundation for this scientific principle.
7.
Every action has an equal and opposite ________
Correct Answer
Reaction
Explanation
This statement is based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. This means that whenever an object exerts a force on another object, the second object exerts a force of equal magnitude but in the opposite direction on the first object. Therefore, the correct answer is "Reaction".
8.
A broom would be an example of a _____________
Correct Answer
C. Third Degree Lever
Explanation
A broom would be an example of a third-degree lever because the effort force is applied at one end (the handle), the resistance force is located at the other end (the bristles), and the fulcrum is located in between (where the handle and bristles meet). In a third-degree lever, the effort force is closer to the fulcrum than the resistance force, which allows for increased speed and range of motion, but with a decrease in force.
9.
Which of these isn't an example of inertia.
Correct Answer
C. An unstoppable object colliding with an unmovable object
Explanation
The statement "An unstoppable object colliding with an unmovable object" is not an example of inertia because it contradicts the principle of inertia. According to Newton's first law of motion, an object at rest will remain at rest and an object in motion will continue moving in a straight line at a constant velocity unless acted upon by an external force. In this scenario, both objects are described as "unstoppable" and "unmovable," which means they would not be subject to any external forces. Therefore, this scenario does not align with the concept of inertia.
10.
What is called when a binary star system explodes?
Correct Answer
C. It's still called a Supernova
Explanation
When a binary star system explodes, it is still referred to as a supernova. A supernova is a powerful and catastrophic event that occurs when a massive star reaches the end of its life cycle and collapses under its own gravity. The explosion releases an enormous amount of energy and results in a bright and intense burst of light. The term "supernova" is used regardless of whether the star system is binary or not.
