The following apply:
Sound is a LONGITUDINAL wave.
Sound is a PRESSURE wave.
Longitudinal waves are waves in which the displacement of the medium is in the same direction as or opposite direction to the direction of wave propagation. An example of longitudinal wave is sound wave. Sound wave is also considered as a pressure wave as the result of the presence of repeating patterns of high and low pressure regions moving through a medium.
The track has a circumference of 400 m. This is the distance traveled per lap.
Because the person made 8 laps, the total distance traveled is
8 * 400 = 3200 m
The time taken for the 8 laps is 14.0 min = 14*60 = 840 s.
The average velocity
= distance/time
= (3200 m)/(840 s)
= 3.8095 m/s
Answer: 3.8 m/s (nearest tenth)
Any type of wetland that has been developed or maintained by humans for uses such as aquaculture, irrigation, or water storage.
<h3>What is a human-made wetland ?</h3>

The Sunderbans are India's biggest wetland. The world's biggest mangrove forest includes Sunderban Wetland.
Hence, the human-made wetland is an artificial wetland.
