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.
Answer:
The function of the pleura is to allow optimal expansion and contraction of the lungs during breathing. The pleural fluid acts as a lubricant, allowing the parietal and visceral pleura to glide over each other friction free. This fluid is produced by the pleural layers themselves.
