Mrs. Vikram's science class notices that a high pressure system bringing cold air is set to move
into their city. Currently, the weather is warm. As
the cold air enters their region, what will most
likely occur?

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)
