True
B
False

B. False

Explanation:

The term "quantitative" is applied in engineering to mean data, methods or information which is measurable. This means it deals with quantities which can be directly measured. The engineering sector is a technical field that utilizes quantitative data or methods to explain relationships and behaviors of quantifiable  variables as applied in a particular research study. For example, using closed-ended questionnaires and surveys to obtain data concerning a concept is a method applied in science and engineering to obtain numerical data in a research project with the aim of making concrete conclusions through analysis of the data obtained. Unlike the term " qualitative" which is applied in science to describe aspects of a research study which are subjective and with no concrete facts to support conclusions due to lack of numerical data.

Hence, the term "quantitative" is often used when discussing engineering arguments or justifications due to the presence of numerical data as a foundation for discussions , justifications and conclusions.

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
