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 option is <em>C) They provide only those statistics related to their jurisdiction.</em>
Explanation:
With the medial being open and advanced more and more, people have come to a realization that many of the facts claimed by the politicians or government agencies are made in favour of them and they show facts as they want the people to view them. Government agencies tend to show statistics which will favour their organization. Hence, most of the people now know that government agencies provide fraud statistics from time to time.
The Social Cognitive Model of change is based on the interplay of three components (social environment, ideas and feelings, and behaviors).
The Social Cognitive Model/Theory states that these are the important factors that influence the behaviour of the individual.
Social Cognitive Model/Theory
- This theory explains the behaviour of the individual with respect to the social environment, personal as well as actions and experiences of others.
- Each behaviour actually helps in influencing the way of thinking as it is resulted because of the social environment as well as the responses of the others.
- In simple words we can say that it is learning theory and out of the four factors, emotions of the individual are considered as the pre determinant of behaviour as well as emotions.
