Explanation:
Given that,
The diameter of a human blood cell is 0.0000062 m. We need to express in scientific notation.
Any no can be written in scientific notation as follows :
n and m are real no and integer respectively
0.0000062 has 5 zeroes before 6. It means its scientific notation is as follows :
Answer:
The most common of these is carbon 12, 13, 14. All of these isotopes have the same atomic number but different mass numbers. Carbon has the atomic number of 6 which means that all isotopes have the same proton number. However, the number of neutrons is different, thus giving different mass numbers.
<span>In this case, the angle of incidence equals the angle of reflection at the point that the light ray strikes the surface. Light is also reflected when it is incident on a surface or interface between two different materials such as the surface between air and water, or glass and water.</span>
Answer:
the molecules speed up and then decrease their speed
