Velocity is an object's rate of change (usually over time) of its displacement.
Oxygen is a product of photosynthesis, therefor lover levels of C02 would be in the area with more water due to more phtosynthetic processes happening converting it into oxygen.
hope this helps, please mark brainliest. :)
Answer:
20 Hz, 20000 Hz
0.0166 m, 16.6 m
Explanation:
The minimum frequency that a human ear can hear is 20 Hz
The maximum frequency that a human ear can hear is 20000 Hz.
v = Velocity of sound = 332 m/s
Wavelength is given by

The longest wavelength that can be heard by the human ear is 16.6 m

The shortest wavelength that can be heard by the human ear is 0.0166 m.
71 MPM (Meters Per Minute)
S = Speed
D = Distance
T = Time
to find the Speed you divide D by your T
