Question 1: How is the force of gravity measured?
Question 2: Which is the smallest country in the world?
As an independent city-state enclaved within Rome, Italy, Vatican City is the smallest country both by size, covering around 44 hectares, and population, with about 825 inhabitants. It's also the spiritual and administrative headquarters of the Roman Catholic Church.
Question 3: What is the highest-grossing film of all time unadjusted for inflation?
As of now, Avengers: Endgame, released in 2019, holds the record for the highest-grossing film worldwide, surpassing Avatar's decade-long hold on the record. However, when adjusted for inflation, Gone with the Wind still holds the record.
Question 4: If you wanted to generate electricity from ocean waves, what device would you likely use?
Wave energy converters extract energy directly from surface waves or from pressure fluctuations below the surface. Multiple designs have been researched and tested, including oscillating water columns, point absorbers, oscillating wave surge converters, and more.
Question 5: How old are the oldest known cave paintings?
The oldest known cave paintings are located in the Cueva de las Manos in Argentina. They are estimated to be between 45,000 and 52,000 years old. Cave paintings have been found on every continent except Antarctica.
Question 6: What branch of philosophy is primarily concerned with the nature of being and existence?
Ontology is the philosophical study of the nature of being, becoming, existence, or reality. It deals with questions concerning what entities exist and how they can be grouped and related within a hierarchy.
Question 7: What is the title given to the head of state in Australia?

Question 9: Which of these is not one of the fundamental forces of nature?
Centrifugal force is not a fundamental force of nature, but rather an apparent force that arises in rotating reference frames. The four fundamental forces are gravitational, electromagnetic, strong nuclear, and weak nuclear forces. These forces govern the interactions between particles and underlie the structure and behavior of all matter in the universe.
Question 10: Which country is often referred to as "The Land of the Rising Sun"?
Japan is often called "The Land of the Rising Sun" due to its easternmost position in Asia, where the sun rises first. The name also comes from the characters used in the Japanese name for Japan, 日本, which can be translated as "sun origin".
The force of gravity is measured in Newtons, named after Sir Isaac Newton who formulated the universal law of gravitation. In this system, the weight of an object - which is the force of gravity acting on it - is its mass times the acceleration due to gravity, typically rounded to 9.8 m/s^2 on the surface of the earth.
