Which equation relates wave speed, frequency, and wavelength?
Correct answer: v = fλ
Wave speed equals frequency multiplied by wavelength: v = fλ. If frequency rises while wave speed stays constant, wavelength must decrease.
Waves, Water & Particle Physics
Test ten science ideas from waves and thermodynamics to nuclear forces, electricity and crystal structure. You'll encounter boiling water at standard pressure, DNA replication, Newton's laws and the unit of inductance, alongside a question about the Latin root of 'science'. Two prompts move into international radio regions and country-code domains. Be ready to switch between a physical law, a numerical classification and the meaning of a technical abbreviation.

The word "science" stems from the word "scire" meaning what?
Correct answer: To know
The English word “science” comes through Latin scientia, meaning knowledge, related to scire, “to know.” The word’s history reflects science’s broad aim of building organised, testable knowledge about the world.

At standard atmospheric pressure, at approximately what temperature does pure water boil?
Correct answer: 212°F
At standard atmospheric pressure, pure water boils at 100°C (212°F). The boiling point changes with pressure, which is why water boils at a lower temperature at high elevations.

Which particle is the force carrier of the strong nuclear interaction in quantum chromodynamics?
Correct answer: Gluon
Gluons are the force-carrying particles of the strong interaction in quantum chromodynamics. They act between quarks and themselves carry the type of charge associated with that force.
Australia, Japan, and Southeast Asia are in which ITU Region?
Correct answer: Region 3
The International Telecommunication Union divides the world into regions for some radio-frequency allocation purposes. ITU Region 3 includes much of Asia and Oceania, including Australia, Japan and Southeast Asia.

Which enzyme joins Okazaki fragments during DNA replication?
Correct answer: DNA ligase
DNA ligase seals the breaks between adjacent DNA fragments by forming phosphodiester bonds in the sugar-phosphate backbone. This joins the Okazaki fragments on the lagging strand into a continuous DNA strand.
What is the unit of electrical inductance?
Correct answer: Henry
The henry (H) is the SI unit of inductance. An inductor resists changes in electric current by producing an induced voltage.
In crystallography, how many Bravais lattices exist in three dimensions?
Correct answer: 14
In three dimensions, crystal structures are described by 14 Bravais lattices. They represent the distinct ways lattice points can be arranged while preserving the translational symmetry of a crystal.
Which of these is Poland's country-code top-level domain?
Correct answer: .pl
The .pl country-code top-level domain is delegated to Poland. A domain ending identifies the domain namespace, not necessarily the language of a website.
Which law states that every action has an equal and opposite reaction?
Correct answer: Newton's third law
Newton’s third law says that when one object exerts a force on another, the second exerts an equal and opposite force on the first. The forces act on different objects, which is why they do not simply cancel each other out.
