Answer:
A hypothesis is something you can test a theory is just a thought that you have.
The extent of sewage treatment required mostly depends on the control of suspended solids and BOD of the sewage. Hence, option C is correct.
<h3>What is Inorganic matter?</h3>
Inorganic matter is substances of mineral origin that are not characterized by primarily carbon-based structures.
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable for discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges.
The main goal of wastewater treatment facilities is to protect humans and the ecosystem from harmful and toxic elements found in wastewater.
Hence, option C is correct.

Answer:
50,000,000 Hz
Explanation:
<em>Rearrange the formula:</em>
wave speed = frequency × wavelength → frequency = wave speed ÷ wavelength
wave speed = 300,000,000m/s
wavelength = 6m
<em>Substitute in the values:</em>
frequency = 300,000,000 ÷ 6
frequency = 50,000,000 Hz
Hope this helps!
