Question

Refer to the data table above. According to the data, what conclusion can be drawn from the data table above?

Option A: Sound doesn't travel through human beings at all.
Option B: Sound travels through human beings faster than through cork.
Option C: Sound travels through human beings slower than through cork.
Option D: Sound travels through human beings and cork at around the same speed.

Answer 1

The conclusion drawn from the data is Option C: Sound travels through human beings slower than through cork. (Option C)

Step-by-step explanation:

The speed of sound in a material is determined by its density and elasticity. Looking at the data table, we observe that the speed of sound in cork is 402 m/s, while the speed of sound in a human body is 1540 m/s. This substantial difference indicates that sound travels through human beings at a significantly slower speed compared to cork.

To arrive at this conclusion, we can calculate the ratio of the speeds:

`\[ \text{Speed ratio} = \frac{\text{Speed in Human Beings}}{\text{Speed in Cork}} \]`

`\[ \text{Speed ratio} = \frac{1540 \, \text{m/s}}{402 \, \text{m/s}} \approx 3.83 \]`

This ratio clearly demonstrates that sound travels approximately 3.83 times faster through cork than through human beings. Therefore, Option C is the correct conclusion.

In summary, the data provides a clear understanding of the speed of sound in different materials, allowing us to deduce that sound travels slower through human beings than through cork, reinforcing the fundamental principles of how sound propagates through different substances.(Option C)
