Air pressure

P(h)

is measured in kilopascals (kPa), and altitude

h

is measured in meters. A meteorologist reports

P'(h)\approx -0.12\ \text{kPa}/100\text{ m}

. What is this rate expressed in pascals per meter (Pa/m)? (Note:

1\ \text{kPa}=1000\ \text{Pa}

.) a)

-0.0012\ \text{Pa/m}

-0.12\ \text{Pa/m}

-1.2\ \text{Pa/m}

-12\ \text{Pa/m}
