Question

What is the basis of the metric measurement system?

Question 1 options:

Its measures are based on divisions that are powers of ten.

It is based on European measurement standards.

It is the only scientific measurement system.

It is based on the wavelength of krypton-86 radiation.

Answer 1

Its measures are based on divisions that are powers of ten.

Step-by-step explanation:

The metric system used by scientists, doctors and mathematicians is the most used worldwide, including the official one in Brazil. This system was created at the time of the Inconfidência Mineira, by French scientists who wanted a system of less arbitrary measures, and that could not be lost. To choose this unit of length, they measured the distance from the Equator to the North Pole. They divided that distance by 10,000,000 and marked that distance on a bar. This unit, they called the metro.

In this system, the units are divided into tenths, hundredths and thousandths, adding the prefixes deci, centi and milli to the meter. They are smaller than the meter by 10, 100 and 1000 times, respectively.

Likewise, the multiples that are 10, 100 and 1000 times greater than the fundamental unit, the meter, were named after the addition of the prefix deca, hecto and kilo.

Answer 2

The answer to this question is ‘A.’

Step-by-step explanation:

The answer to this question is ‘A’ Metric measurement system is a decimal-based measurement system. That’s why it is based on divisions that are powers of ten. In Europe, people have commonly used a gram-centigrade based system for measurement. There is a total of two scientific methods of analysis. The metric system is not anymore based on the wavelength of krypton 86 radiation.
