Answer:
3.77 Hz
Explanation:
The beat frequency that is heard can be calculated using the following equation:

<u>Where:</u>
f₁ = 110 Hz

<u>With:</u>
<em>T₁ = 594 N </em>
<em>T₂ = 554 N </em>
Hence, the beat frequency is:
Therefore, the beat frequency that is heard when the hammer strikes the two strings simultaneously is 3.77 Hz.
