Answer:
Technology
Explanation:
Technology is always changing and improving. It will change the way we communicate and make it easier and faster.
The answer is "<span>Stimulus Discrimination".
“us” in the above question stands for </span><span>unconditioned stimulus. </span>Discrimination is a term
utilized as a part of both operant and classical conditioning. It includes the
capacity to recognize between one stimulus and similar stimuli. In the two
cases, it implies just reacting to specific stimuli yet not to those that are
similar.
This would be mostly Great Britain and France: you can see that many countries today still speak English and French in Africa.
Portugal also had some land under its control: Angola and Mozambique.
Now, I am unsure about the forth one, as there is a number of countries that had a colony, but were not as present as the ones I mentioned above. These are Belgium, Italy, Germany and Spain.
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.
