Answer:
The velocity of the sound wave is 540 meters per second.
Explanation:
The sound is a consequence of mechanic waves, the velocity of a mechanic wave ([tex]v[/tex]), in meters per second, is determined by following formula:
[tex]v = \lambda\cdot f[/tex] (1)
Where:
[tex]\lambda[/tex] - Wavelength, in meters.
[tex]\lambda[/tex] - Frequency, in hertz.
If we know that [tex]f = 2700\,hz[/tex] and [tex]\lambda = 0.20\,m[/tex], then the velocity of the sound wave is:
[tex]v = \lambda\cdot f[/tex]
[tex]v = 540\,\frac{m}{s}[/tex]
The velocity of the sound wave is 540 meters per second.

If water vapor is invisible, how are we able to see clouds?
Answer:
Clouds are made of water vapor
Explanation:
It's true that clouds contain water, but they aren't made of water vapor. If they were, you wouldn't be able to see them. The water that makes up clouds is in liquid or ice form. The air around us is partially made up of invisible water vapor.

Answer: Preserving wetland and coastal mangrove habitats
Explanation:
The wetland must be preserved using physical barriers and planting trees around wetland this will protect the outflow of water which is expected during rain into the land. Also the maintained of mangrove habitats is necessary in flood prone coastal areas. The mangrove trees hold on the soil and sediments on the coastal areas further prevent the erosion. The root, canopy of the trees and the tree trunks can prevent the high speed waves generated during storm and thus help in flooding the urban areas.
