Which of the following is not an example of critical thinking?
Mkey [24]

Hi!

Your answer is C.

A is an example because it's not good to only make identify one solution; you need backups or a variety of ways.

B is an example because, hey, not everything is true! Especially on the internet. Questioning source information is great because then you are sure what you are seeing is unbiased and accurate.

C is NOT an example. As stated above, you need a variety of solutions, but you can't just pick the first solution; you want to pick the <em>best</em> solution for the problem at hand.

D is an example. As stated above, questioning source information is great, but then you need to also verify it, because, like said before, not everything is true.

Em uma estação elevatória de água tratada eleva 144 m³/h de água para um reservatório o através de
Genrish500 [490]

Explanation:

The frictional resistance of the various pipes are given by the

K value in the table which may be used with the formula

hf = KQ2

to relate the magnitude of head loss hf in the pipeline

to the volumetric flow rate, Q. Water is drawn at the constant flow

rates from the network at nodes C and D. The static heads

(elevation + pressure head) at nodes B, C and D are 100m, 65m

and 61m respectively above the local datum. Calculate the

discharges at C and D and the water level in reservoir A. (The

data has been added to the diagram to aid the solution)

Use no more than 3 iterations and 3 significant figures.

Answer:

d. All of the above

Explanation:

A scale can be defined as an ordered numerical or alphabetical sequence that is typically used for taking measurements such as size, weight, height, length, etc. Also, a scale is used in the field of science to assign magnitude to physical activities and natural phenomenons such as an earthquake using the Richter scale.

In Science, there are four (4) main scales of measurement and these includes;

1. Interval scale: data can be arranged in an ordering scheme and subtracting its differences is meaningful. Examples are year, temperature, time etc.

2. Ratio scale: data can be arranged in an ordering scheme and subtracting its differences is meaningful with respect to the value of true zero. Examples are height, price, weight, distance etc.

3. Ordinal scale: data can be arranged in an ordering scheme but subtracting its differences is meaningless or impossible. Examples are happy, sad etc.

4. Nominal scale: it is characterized by data that are non-numerical, comprises of categories, labels or names and can't be arranged in an ordering scheme.

<em>Hence, scales can represent;</em>

<em>a. A range of information. </em>

<em>b. A range of resources. </em>

<em>c. Proportional measurement. </em>
