According to the kinetic molecular theory of gas: a All molecules move in the same direction
b Molecules are stationary

random motion in all directions
d None of the above

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.

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)
