Explanation: Since air has mass, it also has weight. The pressure of air at a given place is defined as a force exerted in all directions by virtue of the weight of all the air above it.
The weight of a column of air contained in a unit area from the mean sea level to the top of the atmosphere is called the atmospheric pressure. The atmospheric pressure is expressed in various units.
Measurement of Air Pressure
Atmospheric pressure is the weight of the column of air at any given place and time. It is measured by means of an instrument called barometer.
The units used by meteorologists for this purpose are called millibars (mb).
One millibar is equal to the force of one gram on a square centimeter. A pressure of 1000 millibars is equal to the weight of 1.053 kilograms per square centimeter.
In other words, it will be equal to the weight of a column of mercury 75 cm high.
The normal pressure at sea level is taken to be about 76 centimeters (1013.25 millibars).
Vertical Variation of Pressure
In the lower atmosphere the pressure decreases rapidly with height.
Answer:
The correct answer is task oriented listening
Explanation:
Task oriented is a listening style in which the individual listening is focused on getting information and being efficient..
Annie taking down extensive note and jotting main ideas can be related to her being efficient and also ensuring she get information.
This is typical of Task oriented listening which focuses on getting information and being efficient as well.
The task that cannot be performed by using the deployment image servicing and management is to add service packs to an image. In addition, deployment image servicing and management or as called as DISM.exe is a command line tool that can be used to service a windows 10 images or online and perform imaging operations. The image based installation is an installation that uses deployment image servicing and management to apply an image of an operating system to a computer. The image is a copy of a previously prepared operating system that has been copied to a file and can include applications as well as the operating system.
