Sir Isaac Newton determined that gravity has a fixed acceleration on Earth. The earth pulls objects towards it with a fixed acce
leration at -9.8 m/s2. This is a _____________ ____________, as it states a scientifically accepted fact about the natural world. A) scientific law B) scientific theory C) natural hypothesis D) scientific evaluation
Scientific laws are laws that are well oberved and proved all around the globe with different measures and different experiments this is because scientific laws they can predict a wide variation of physical phenomenoms, in this case since gravity is observable and can be proved with experiments that are consistent all around the globe, is a scientific law.
A. Scientific Law. The mathematics surrounding the acceleration due to gravity is a law. It is calculated from the universal law of gravity. However, the explanation of the idea of gravity is a theory. This falls back to the idea that science is about disproving ideas that we currently believe, rather than proving ideas are correct. Unless we can disprove an idea, we have to accept the possibility that it is true; the more trials we have of being unable to disprove something, the more accepted it will be. Yet, no idea can be without doubt and certainty be accepted for what it is. So, to sum it up, scientific laws are factual descriptions (by formula or word) of phenomenon which always occur given specific conditions. On the other hand, scientific theories are explanations of the causes underlying these phenomena, the explanation formulated in such a way that they can be disproven.
Sodium chloride, NaCl, is formed when a sodium atom transfers its electron to a chlorine atom. The difference in charge between the two atoms creates a(n) electrostatic attraction that bonds them together.
The correct answer among all the other choices is 4. This is the number of the lowest energy level that contains an f sublevel. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
