A Metric System Knowledge Quiz
(8).jpg "A Metric System Knowledge Quiz - Quiz")
Welcome to "A Metric System Knowledge Quiz." The French standards meter originated in the 1970s as 1/ten-millionth of the distance from the equator to the North pole along a meridian through Paris. But it's history started centuries ago with the work of Nicolaus Copernicus in 1543. So, what do you know about the meter? Take our quiz and find out now.

What was the general scaling system?
- A.
The archives
- B.
The metre of renaissance
- C.
The metre des archives
- D.
The metre of Rousseau
Correct Answer
C. The metre des archivesExplanation
The correct answer is "The metre des archives". The metre des archives was a general scaling system used in archives. This system was specifically designed for measuring and scaling documents in archives, ensuring accurate and consistent measurements. It was widely used during the time period in question and was an important tool for organizing and categorizing documents in archives.Rate this question:

When was the metric system adopted in France?
- A.
In 1802
- B.
In 1780
- C.
In 1770
- D.
In 1799
Correct Answer
D. In 1799Explanation
In 1799, the metric system was adopted in France. This adoption was a result of the French Revolution, which aimed to standardize measurements and create a more rational and universal system. The metric system was designed to be decimal-based, making it easier to use and understand. Its adoption in France marked a significant shift away from the traditional system of measurement and paved the way for its eventual global acceptance.Rate this question:

When did the metric system become the sole legal system of weights and measures?
- A.
From 1830
- B.
From 1820
- C.
From 1801
- D.
From 1810
Correct Answer
C. From 1801Explanation
The metric system became the sole legal system of weights and measures from 1801. This means that starting from that year, all measurements in weights and measures were required to be done using the metric system.Rate this question:

What is krypton?
- A.
It's a liquid at room temperature allowing for easier isotopic enrichment
- B.
It's a rock
- C.
It's a gas at room temperature allowing for easier isotopic enrichment.
- D.
It's a planet
Correct Answer
C. It's a gas at room temperature allowing for easier isotopic enrichment.Explanation
Krypton is a gas at room temperature, which makes it easier to carry out isotopic enrichment processes. Isotopic enrichment involves separating and concentrating specific isotopes of an element, and it is typically done in the gas phase. The fact that krypton is a gas means that it can be easily manipulated and processed to enrich specific isotopes, making it a suitable element for this purpose.Rate this question:

What is the original definition of the metre?
- A.
It's a stretched distance.
- B.
It's the length equal to 1 wave length in vacuum of radiation corresponding to the transition between the levels 2p10 and 5d5 of the krypton 86 atom.
- C.
It's the length equal to 1650 763.73 wavelengths in vacuum of radiation corresponding to the transition between the levels 2p10 and 5d5 of the krypton 86 atom.
- D.
It's the length equal to 165 wavelengths in vacuum of radiation corresponding to the transition between the levels 2p10 and 5d5 of the krypton 86 atom.
Correct Answer
C. It's the length equal to 1650 763.73 wavelengths in vacuum of radiation corresponding to the transition between the levels 2p10 and 5d5 of the krypton 86 atom.Explanation
The original definition of the metre is the length equal to 1650 763.73 wavelengths in vacuum of radiation corresponding to the transition between the levels 2p10 and 5d5 of the krypton 86 atom.Rate this question:

What is the 1983 and more modern definition of the metre?
- A.
It's the length of the path traveled by light in a vacuum in 1/299,792,458 of a second.
- B.
It's the length of the path traveled by light in a vacuum in 1/500 of a second.
- C.
It's the length of the path traveled by light in a vacuum in 1/230 of a second.
- D.
It's a stretched distance
Correct Answer
A. It's the length of the path traveled by light in a vacuum in 1/299,792,458 of a second.Explanation
The correct answer is the first option: "It's the length of the path traveled by light in a vacuum in 1/299,792,458 of a second." This answer accurately describes the 1983 and more modern definition of the meter, which is based on the speed of light in a vacuum. It states that the meter is defined as the distance that light travels in 1/299,792,458 of a second. This definition provides a precise and standardized measurement for the meter.Rate this question:

What's the purpose of airy points?
- A.
They are used to measure the condensation phase of liquids.
- B.
They are used to measure the pressure in liquids.
- C.
They are used to measure the density of the air.
- D.
They are used for precision measurement.
Correct Answer
D. They are used for precision measurement.Explanation
Airy points are used for precision measurement. These points are created by focusing a beam of light through a small hole onto a surface, resulting in a pattern of concentric rings. By measuring the size and spacing of these rings, precise measurements can be made. Airy points are commonly used in fields such as optics and astronomy to accurately determine the position and alignment of objects.Rate this question:
