The first energy shell around a nucleus can hold electrons. The second energy shell can hold . A. 0, 10 B. 10, unlimited C. 2, 8 D. 8, 18

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
