Why is it important that scientists in different countries check their ways of measuring a KG against the same standard mass?
When someone describes something as having a mass of one kilogram, it is important that everyone else understands what one kilogram is. Therefore there has to be an agreed definition of a kilogram. This means there has to be a standard kilogram that everyone can use to set their own kilogram. At present the standard kilogram is a block of platinum held in Paris, there are plans to redefine the kilogram in terms of the reaction between a fixed magnet and the magnetic field set up by an electric current passing through a wire, the kilogram will still weigh the same but the means of setting it will change.
What else can I help you with?
Scientists in all countries use the system of measurement what the answer?
Scientists in all countries use the International System of Units (SI) for measurements. This system provides a universal standard for measuring physical quantities such as length, mass, time, and temperature. It ensures consistency and accuracy in scientific measurements across different countries and disciplines.
What are two reasons a common measuring system is important?
a) The use of a common measuring system makes it easier for people from different countries to communicate with each other. b) The use of a common measuring system means a maesurement in that unit has the same value anywhere in the world.
What important discoveries about earth the planets and the sun came from the scientists of Alexandria?
They found the diameter of the Earth by measuring the angle of the Sun above the horizon at noon at two different places, Alexandria and Aswan. The 7 degree difference gave the Earth's circumference as 360/7 times the distance between those two cities.
How do scientists use measuring?
Scientist use measuring to determine the effects of an action. They measure the property of the object, process or substance before the action and after. The difference in the two measurements reveals some information which they use to validate hypotheses.
What three countries don't use the SI measuring system?
USA, Liberia and Burma.
Why do you think it is important that scientists in different countries all check their ways of measuring a kilogram against the same standard mass?
To ensure that no no matter what country you are working in, the units of measurement you are using are the same across the world and therefore that experiments are repeatable.

Why are measurement important to scientists?
Measurements are crucial for scientists as they provide objective data to support or refute hypotheses. Accurate measurements ensure that results are reproducible and verifiable, which are fundamental principles in scientific research. Additionally, measurements help scientists quantify relationships between variables and make comparisons between different studies.

What is the scientists tool for measuring liquids?
A beaker.
Why do scientist use the metric system?
It is a more precise way of measuring
Discuss the advantages and disadvantages of national income of an economy?
main advantages of national income:- 1:Study of All important sectors & Industries 2:An important fact for measuring economic development of Develop countries 3:Analysis of different sectors
What is the system of measuring units used by scientists?
SI system is used by scientists. It is one of the standard system adopted by scientists.
Why do scientists use a common measuring system?
to share their data
What do scientists use to measure volume of a liquid?
A measuring cylinder
Why are there different types of measuring temperature?
what are the different skills in measuring temperature
What are the evidences for Helium and Hydrogen in sun?
Scientists can determine the contents of stars using spectrometer (spectrograph or spectroscope.) Basically different compounds give off different wavelengths of of light. By measuring the light you can identify the compound.
