<h3><u>Answer;</u></h3>
A. Skeletal muscles, which are made of fibers, nerves, and blood vessels, contract in order to make the body move.
<h3><u>Explanation</u>;</h3>
- <em><u>Muscular tissues functions in movement and locomotion through its direct connection with the skeletal system. </u></em>
- <em><u>Skeletal muscles are responsible for moving the body. The skeletal muscle contractions pull on tendons, which as attached to bones. When the skeletal muscle contraction causes the muscle to shorten, the bone and thus the body par will move. </u></em>
- <em><u>Skeletal muscles also provide structural support for the entire body. </u></em>
To solve this problem we will apply the concepts related to the Doppler Effect, defined as the change in apparent frequency of a wave produced by the relative movement of the source with respect to its observer. Mathematically it can be written as
Here,
= Frequency of the source
= Speed of the sound
= Speed of source
Now the velocity we have that
Then replacing our values,
Therefore the frequency of the observer is 1047.86Hz
