Question 10

You might wonder why a millibar isn't exactly 1/1000th of an atmosphere. The unit is actually related to the old CGS units because atmospheric pressure is close to this unit. In CGS units 1 bar = 1000 dynes/cm2. Pressure is often incorrectly reported as kg/cm2, which is neither a legitimate pressure unit nor a standard SI unit pressure is force/unit area, and kg are a mass unit, and SI units never mix kg and cm.. So let's straighten out your friends on these units. Standard air pressure in this incorrect unit is 1.034 kg/cm2. The weight of a kg at the earth's surface is 980,000 dynes. So what is standard air pressure in millibars?

Accepted Answer

A)  1013 mb 
B)  1143 mb 
C)  750 mb 
D)  890 mb 
A)  1013 mb 
B)  1143 mb 
C)  750 mb 
D)  890 mb

Accepted Answer

A)  1006 
B)  1028 
C)  1000 
D)  1013 
A)  1006 
B)  1028 
C)  1000 
D)  1013

Question 12

If you live in southwestern North America and are experiencing drought conditions, what do you hope will happen?

Accepted Answer
