Analyze the data to identify the mathematical relationship between the amplitude and energy of a mechanical wave. If mechanical wave [tex]$A$[/tex] has an amplitude of 4 cm and mechanical wave [tex]$B$[/tex] has an amplitude of 5 cm, what will be the relationship between the energy carried by the two waves?

\begin{tabular}{|l|l|}
\hline
Amplitude & Energy \\
\hline
1 unit & 2 units \\
\hline
2 units & 8 units \\
\hline
3 units & 18 units \\
\hline
4 units & 32 units \\
\hline
5 units & 50 units \\
\hline
\end{tabular}

A. Wave [tex]$A$[/tex] has about 1.6 times more energy than wave [tex]$B$[/tex].
B. Wave [tex]$B$[/tex] has about 1.6 times more energy than wave [tex]$A$[/tex].
C. Wave [tex]$A$[/tex] has about 1.25 times more energy than wave [tex]$B$[/tex].
D. Wave [tex]$A$[/tex] has about 1.15 times more energy than wave [tex]$B$[/tex].



Answer :

To analyze the relationship between the amplitude and energy of a mechanical wave, let's take a look at the provided data:

[tex]\[ \begin{array}{|c|c|} \hline \text{Amplitude (units)} & \text{Energy (units)} \\ \hline 1 & 2 \\ \hline 2 & 8 \\ \hline 3 & 18 \\ \hline 4 & 32 \\ \hline 5 & 50 \\ \hline \end{array} \][/tex]

We are given the amplitudes for waves [tex]\( A \)[/tex] and [tex]\( B \)[/tex] as follows:
- Wave [tex]\( A \)[/tex] has an amplitude of 4 units.
- Wave [tex]\( B \)[/tex] has an amplitude of 5 units.

Using the provided data, we can identify the energy corresponding to these amplitudes:
- For wave [tex]\( A \)[/tex] with an amplitude of 4 units, the energy is 32 units.
- For wave [tex]\( B \)[/tex] with an amplitude of 5 units, the energy is 50 units.

Next, we need to find the ratio of the energy of wave [tex]\( B \)[/tex] to the energy of wave [tex]\( A \)[/tex]:
[tex]\[ \text{Ratio of energy}\, B \text{ to energy}\, A = \frac{\text{Energy of } B}{\text{Energy of } A} = \frac{50}{32} = 1.5625 \][/tex]

Interpreting this ratio:
- Wave [tex]\( B \)[/tex] has [tex]\( 1.5625 \)[/tex] times more energy than wave [tex]\( A \)[/tex].

Thus, the correct choice is:
B. Wave [tex]\( B \)[/tex] has about 1.6 times more energy than wave [tex]\( A \)[/tex].

So, the answer to the question is:
B. Wave [tex]\( B \)[/tex] has about 1.6 times more energy than wave [tex]\( A \)[/tex].
