Answer:
The answer to your question is because of the force of friction between the ball and the ground.
Explanation:
Exactly, Newton's first law states that every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impress on it.
After analyzing Martin's experiment we could conclude that Newton's first law of motion is wrong but we must remember that between a body and the surface there is a force of friction that causes that the object comes to stop.
We can not see this force but it is there.
The most important factor would be the number of electrons of the compound. Compounds need to achieve electron configuration the same as the noble gas. Noble gases are the most stable elements in the periodic table. Hope this answers the question.
Answer:
A. Modern atomic theory is, of course, a little more involved than Dalton's theory but the essence of Dalton's theory remains valid. ... Also, there are different kinds of atoms (differing by their masses) within an element that are known as "isotopes", but isotopes of an element have the same chemical properties.
B. The explanation becomes a scientific theory. In everyday language a theory means a hunch or speculation. Not so in science. In science, the word theory refers to a comprehensive explanation of an important feature of nature supported by facts gathered over time.
It will be between 0 and 100 and lower than 50 so the answer is 40
Answer:
See below
Explanation:
9.045/8.492 * 100% = 106.5%
There was other solids already dissolved in the water, or dust or other contaminants got into the water. ....or the measurement was incorrect. (like maybe the solid was still wet?)
