Atoms<span> are </span>neutral<span>; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a </span>neutral atom<span> to give a positive ion or adding electrons to a </span>neutral atom<span> to give a negative ion.</span>

Answer:
v = 10 m/s
Explanation:
Given that,
Distance covered by a sprinter, d = 100 m
Time taken by him to reach the finish line, t = 10 s
We need to find his average velocity. We know that velocity is equal to the distance covered divided by time taken. So,
v = d/t
Hence, his average velocity is 10 m/s.
It should be C. If the object is denser than the fluid, it will sink. If it isn't, it will float
