Suppose that you measure a pen to be 11.1 cm long. Convert this to meters.

0.111 m

Explanation:

Step 1: Given data

Length of the pen: 11.1 cm

Step 2: Convert the length of the pen to meters

In order to convert one unit into another, we need a conversion factor. In this case, we will use the conversion factor 1 meter = 100 cm. The length of the pen in meters is:

11.1 cm × (1 m/100 cm) = 0.111 m

not clear

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.
