<h2>Answer:</h2>
The correct answer is option C which is, "empirical evidence that was collected during the experiment".
<h3>Explanation:</h3>
Empirical evidence are the observations and data values collected during the experiment by using the senses.
Like if your are experimenting involving a chemical reaction, the temperate or color changes during the reaction should be counted in the interpretation of the results.
Hence the correct option is C.
I think the answer is Bell 4 may have either a positive or neg
Answer:
The wavelength of the sound waves are, λ = 26.92 m
Explanation:
Given data,
The frequency of the sound waves, f = 13 Hz
The speed of sound waves in air, v = 350 m/s
The velocity of the wave in the medium is equal to the product of its wavelength and its frequency.
The formula for the wavelength of the waves is,
λ = v / f
Substituting the given values in the above equations,
λ = 350 m/s / 13 Hz
= 26.92 m
Hence, the wavelength of the sound waves are, λ = 26.92 m
