Answer :
Atmospheric pressure at sea level is represented by 14.7 Psi, 29.8 inches Hg, and 101.3 kPa; thus, the answer is all of the above.
The atmospheric pressure at sea level can be represented by different units, and the values given in the question correspond to the same atmospheric pressure but expressed in various measurement systems. These values are 14.7 Psi (pounds per square inch), 29.8 inches Hg (inches of mercury), and 101.3 kPa (kilopascals). Therefore, the correct answer to which of the following would represent atmospheric pressure at sea level is D. All of the above.
