Swahili, Their languages are mostly widely used for inter-ethic communication. Their type of language is spoke by over 3,000 million people.
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:
Non controversial pattern such as a topical, chronological, or geographical
Explanation:A hostile audience is an antagonistic audience that is looking for very single Opportunity to ridicule the speaker,in this case the speaker has to organise his speech using non controversial patterns such as topical, chronological or geographical. The presenter should prevent every form of jokes during his or Presentation in order to prevent the chances of being bullied, insulted or embarrassed.
He wanted one reform and that is that the Church would not insist that he keep His vow to God and remain celibate. The Church does not allow one to break their vows to God and remain a priest. He eventually married a nun which caused her to break her vows as well.
Answer: B. Reliability
Explanation: Reliability is the act of establishing the degree of accuracy or dependency of the outcome or output of a measurement, calculation or experiment. Establishing the reliability of an experiment is aimed at expunging doubt in an experiment or measurement. Reliability of an experiment can be established by repetitive performance of the experiment to determine if it yields the same result or almost similar result which is consistent, reproducible and reliable.
If an experiment is highly reliable, it will yield a consistent, reliable and reproducible result, However, experiments with low reliability will yield inconsistent, unreliable and non- reproducible result.
