The needle of an aneroid barometer points to 30.05 on the dial. This indicates that the barometric pressure is _______________.
AI Explanation
The correct answer is A) 30.05 inches of mercury.
The needle of an aneroid barometer directly indicates the barometric pressure in inches of mercury. When the needle points to 30.05 on the dial, this means the current barometric pressure is 30.05 inches of mercury.
The other options are incorrect because:
B) "falling" does not describe the pressure value, only the trend.
C) 30.05 millimeters of mercury is a different unit of measurement.
D) 30.05 millibars is also a different unit of measurement, not the one used for aneroid barometers.
