Scientists use the metric system when gathering data and performing experiments. Which of the following statements about the metric system

are true? Select three correct answers

A Scientists need a common system of measurement in order to gather qualitative data

B. The units of the metric system are scaled on multiples of 10, making mathematical calculations easier to perform

c. The units of the metric system include kilograms for mass, meters for length, liters for volume, and degrees Celsius for temperature

D. Scientists often retest others' experiments, so a common system of measurement is essential.

answers a b and d are right

The correct answer will be options - A, B and D.

Explanation:

The metric system is an internationally accepted decimal system of the measurement which was adopted in France in 1795. This system is now widely accepted and used system in the world.

The metric units are based on the division and multiplication by an integer of ten thus, units can be scaled on the 10 which makes the calculation easy.

The metric system was accepted as the international system of units in 1875 when the International Bureau of Weights and Measures was established. The motto of this system was that it could be followed by all people all the time.

Thus, the selected options are the correct answers.
