The density of water is 1 g/cm3. Brent used the following method to convert 1 g/cm3 to kg/m3. (1 kg = 1,000 g and 1 m = 100 cm)
What is the error in Brent's conversion method?

A - 1 kg should be written as 1 g.
B - (1 m)3 should be written as (1 cm)3.
C - 1,000 kg should be written as 1,000 g.
D - (100 cm)3 should be written as (100 m)3.

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.
