The kind of investigations might have led to our current understanding of matter and energy is research and measurement.
It is important for scientists to use the same scientific method and consistent measurement units in order to get the correct value while analayzing.
<h3>What is matter?</h3>
The matter has volume and space occupied.
When conceivable the researcher endeavors to test his speculations via painstakingly planned and controlled tests that will yield quantitative instead of subjective outcomes.
Thus, the kind of investigations might have led to our current understanding of matter and energy is research and measurement.
It is important for scientists to use the same scientific method and consistent measurement units in order to get the correct value while analayzing.

Which of the following pairings are more likely to be held together with the strong nuclear force
Explanation:
1.What does a strong nuclear force do in an atom? It repels electrons from other electrons. It repels protons from other protons. It attracts protons and neutrons.
2.The chain reaction requires both the release of neutrons from fissile isotopes undergoing nuclear fission and the subsequent absorption of some of these neutrons in fissile isotopes.
3.The strong nuclear force holds most ordinary matter together because it confines quarks into hadron particles such as the proton and neutron. In addition, the strong force binds these neutrons and protons to create atomic nuclei.
Mass of yellow train, my = 100 kg
Initial Velocity of yellow train, = 8 m/s
mass of orange train = 200 kg
Initial Velocity of orange train = -1 m/s (since it moves opposite direction to the yellow train, we will put negative to show the opposite direction)
To calculate the initial momentum of both trains, we will use the principle of conservation of momentum which
The sum of initial momentum = the sum of final momentum
Since the question only wants the sum of initial momentum,
(100)(8) + (200)(-1) = 600 m/s
Einstein’s theory can found E = mc 2
Issac Newton was found universal gravitional (gravity) opinion.newton’s laws can be revised over time, but einstein’s theory of relativity
