Answer:
b.) pneumatic system
Explanation:
This system uses compressed air to transmit and control energy
Answer: v= 195.2 m/s
Explanation:
The centripetal acceleration acts on the bottom of the test tube trying to take it closer to the axis of rotation, and it is defined by the following expression:
ac = v² / r
We know that ac = 5.4. 10⁴ . g = 5.4.10⁴.9.8 m/s²
Expressing r in m ⇒ r = 0.072 m.
So, the only unknown that remains is v, which is the linear speed of the bottom of the test tube, which we want to find out:
v = √ac. r = √5.4.10⁴.9.8 m/s². 0.072 m = 195.2 m/s

Answer: the answer is plagiarism.
Explanation: Plagiarism is the act of taking credit from someone else's works or ideas, without acknowledging the author. <u>Conflict of interest</u> occurs when an employee has <u>interests that are at odds to each other</u>, which isn't shown at the excerpt given in the exercise. <u>Fabrication</u> is the <u>creation of intellectual property</u>, also not shown in the exercise, and <u>falsification</u> is the <u>creation of a scientific hypothesis</u> that <u>cannot be verified</u> by lack of practical evidence, which is not the case described as well.
Answer:
The option that is best described as a way engineers can test and investigate how things should be under certain circumstances is;
Explanation:
Modeling is a tool an engineer can use for the physical representation of a system that will facilitate the definition, testing and analysis, communication, data generation, data verification and data validation of given concepts
Models also aid in setting specifications, supporting designs, and verification of a given system
Therefore, with modeling engineers can investigate the behavior of systems under given environmental conditions.
