Answer: acoustic power

Explanation: A sound wave is a mechanical wave, so the energy is related to the intensity and the frequency of the same. The rate of "sound energy" as a function of time is called the "sound power" or "acoustic power" which is the rate at which sound energy is emitted or received.

If the acoustic power increases in a given point in space, this means that the point is receiving more sound energy, and then the loudness of the sound also increases at that point.

Classify each label into the correct category of human red blood cell.

Mazyrski [523]

Classifying each label into the correct category of human red blood cell

A) Human red blood cell shrinks

Cells placed in hypertonic solution
More water moves out of cell

B) Normal Human red blood cell

Cell placed in isotonic solution
Water enters and leaves at the same rate

C) Human red blood cell swells

Cell placed in hypotonic solution
More water moves into cell

<h3>Types of solution</h3>

A hypertonic solution is a solution with a higher concentration to its surroundings ( i.e contains more solutes like electrolytes than its surroundings ). when a cell is placed in such solution is shrinks gradually and dies off through a process known as plasmolysis. while a hypotonic solution is a direct opposite of a hypertonic solution. Also An isotonic solution is a solution with the same concentration with its surrounding solution.

Hence we can conclude that the classification of each label into the appropriate category are as listed above.

You are given five integers and your task is to find the smallest of them

Vikentia [17]

The minimum number of comparisons to find the smallest number from 5 integers is 4.

<h3>How to find the Smallest Integer?</h3>

Let the five numbers be a,b,c,d and e.

Let s be an integer

Comparison 1:

a and b will be compared first and the smaller number of them will be equal to s

Comparison 2:

Now, a smaller number between a and b that is s will be compared with c. Similarly, the smaller number of both numbers will be taken as s in the next comparison.

Comparison 3:

Likewise, s and d will be compared and a smaller number will be taken as s for the next comparison

Comparison 4:

Likewise, s and e will be compared and a smaller number will be taken as s for the next comparison.

After 4th comparison, s will be equal to smallest number of 5 integers.

Thus;

Total comparisons = 4

Therefore, the minimum number of comparisons to find the smallest number from 5 integers is 4.

Point (20, 5) is on the graph of inverse variation. Which of the following ordered pair is on the graph?.

Bess [88]

The point $(10, 10)$ is on the graph.

<h3>Procedure - Inverse variation</h3><h3 /><h3>Inverse variation model</h3><h3 />

An <em>inverse</em> variation is represented by the following formula:

$y = \frac{k}{x}$ (1)

Where:

$x$ - Independent variable.
$y$ - Dependent variable.
$k$ - Proportionality constant.

We can eliminate the proportionality constant by creating the following relationship:

$x_{1}\cdot y_{1} = x_{2}\cdot y_{2}$ (2)

<h3>Determination of another point</h3>

If we know that $x_{1} = 20$ , $y_{1} = 5$ and $x_{2} = 10$ , then the remaining variable is:

$y_{2} = \left(\frac{x_{1}}{x_{2}} \right)\cdot y_{1}$

$y_{2} = \left(\frac{20}{10} \right)\cdot (5)$

$y_{2} = 10$

The point $(10, 10)$ is on the graph. (Correct choice: C) $\blacksquare$
