Answer:
C. Theories
Explanation:
Theories basically explain why of research findings. By definition, theories help us understand, explain, and predict the occurrence of a phenomena. In research, theories support research findings by explaining how the variables involved influence each other not merely based on observation during this one experiment. It also helps validate the findings by relating it to theories of previous work.
Concept: The frequency won't change in water or in air.
Since wavelength x frequency = speed, wavelength is proportional to speed.
So, Middle C has a longer wavelength in water than in air.

Julianne’s displacement from her origin is equal to 10.015 kilometers.
<u>Given the following data:</u>
- Distance B = 8.5 km, Northeast.
To calculate Julianne’s displacement from her origin:
<h3>How to calculate displacement.</h3>
We would denote the two (2) unit vectors along the East and Northeast directions by i and j respectively.
<u>Note:</u> Northeast is at angle of 45° with the East.
In terms of vectors, the distances becomes:
Distance A = 2i
<u>For the </u><u>resultant displacement</u><u>:</u>
D = 10.015 kilometers.
