Air is forced through the water to remove gases is called?

Answers

Answer 1

Answer: The process through which air is forced through water to remove gases is called aeration. Aeration is often used as a major step in water treatment plants to remove unwanted gases such as carbon dioxide, odors, and other impurities in water. The process also allows dissolved metals such as iron to oxidize.

Firstly it is best to describe the shape and structure of an atom, an atom's system and structure is like of the solar planet, the heliocentric view where the sun is the neutrons and protons and the planets are the electrons. Moreover, the electrons are outside these neutrons and protons surrounding the entire system of its atomic structure. Its movement is like of a planet.

An energy level also known as electron shell, or just shell is a location around an atom where electrons with a specific energy value, or quantum number may be found.

A wheelbarrow is experiencing two forces. One is pushing 5 N to the east and the other 5 N in the exact opposite direction. What must be true of the wheelbarrow's motion?

Answers

Answer:

its acceleration must be 0.

Explanation:

According the second Newton's law, the net force applied in a object is equal to the mass of the object multiplied by its acceleration:

$F_(net) =m.a$

In this case, the net force is

$F_(net)=5N-5N=0$

What makes sense since both forces have the same value and opposite directions.

Since the mass of the object can't be zero, the acceleration is the one that must be 0 in order fulfill the equation of the second newton's law.

Another option is that, since both forces are opposite, the wheelbarrow could be at rest. Though this is correct, this is not always true.

In conclusion, the only statement that always is true about the wheelbarrow's motion is that its acceleration must be 0.

Assuming no other forces are acting on the wheelbarrow, it must be stationary.

A force of 100 newtons is used to move an object a distance of 15 meters with a power of 25 watts. Find thework done and the time it takes to do the work.

Answers

work is distance * force so 15*100=1500

and to find time you know power = diastance * force / time

so 25=15*100/t

25=1500/t

25/1500=t

.016=time

Final answer:

The work done is 1500 Joules and the time required to do the work is 60 seconds.

Explanation:

The subject at hand is related to concepts in physics, specifically work and power.

To find the work done, we use the formula Work = Force x Distance. Substituting the given values:

Work = 100 Newtons x 15 meters = 1500 Joules

To find the time required to do the work, we use the formula Power = Work / Time. Substituting the given values and rearranging the formula to solve for Time gives us:

Time = Work / Power = 1500 Joules / 25 Watts = 60 Seconds

What is a statement that summarizes a pattern found in nature? A. a scientific law B. a fact C. a scientific theory D. a hypothesis

Answers

A Scientific law is a statement that summarizes a pattern found in nature.

Further Explanation:

A fact is a natural observation which remains the same for several repeated testing under the same circumstances. But a fact cannot be considered a law because it could be proven wrong at some point.

A scientific law is also a fact with a wider scope of being true as compared to a fact. An observation is categorised as a scientific law only when it is true in each and every condition and has a larger scope of being true.

A scientific theory is an explanation of a natural phenomenon based on the scientific law by several testing and observations. A scientific theory is not always true and it can change for a phenomenon based on the new evidences found.

A hypothesis is a mere prediction of a situation without any testing and observation. It is simply an idea behind any observation and it is yet to be tested whether it holds true for the condition or not.

Therefore, a scientific law is the one that explains the patterns and observed phenomenon in nature and holds true in every situation.

Subject: Physics

Keywords: Statement that summarizes, pattern found in nature, scientific law, scientific theory, fact, hypothesis, wider scope, always true.

A. scientific law is a statement that summarizes a pattern found in nature. It is describes an observed phenomenon and has predictive power: it can describe what will happen given a set of initial conditions. Often, a scientific law may be expressed as a mathematical equation.

FURTHER EXPLANATION

B. A fact is an observation that is found to be true by repeated testing. Unlike a scientific law, however, a fact has a level of uncertainty. It is only held true until they are proven false. They are also more specific and localized observations compared to scientific laws which are more general and broad in scope.

C. A scientific theory is an explanation for an observed phenomenon. It attempts to explain in detail why and how an observed phenomenon described by a scientific law happens. It is a hypothesis that has been confirmed through time by repeated testing and validation of the scientific community. However, a theory is not set in stone. When new evidence is found that refutes an existing theory, the theory may be changed or abandoned.

D. A hypothesis is a tentative prediction and explanation about the relationship between two variables – the dependent and independent variables. It is a basic idea and has not been tested yet but will soon be subjected to testing to check whether it holds merit based on the data. Hypotheses may be proven valid or not through testing and experimentation.
