Answer:
the higher the frequency and the higher amplitude, the more energy there is.
Explanation:
waves carry energy uh The higher the frequency, the shorter the wavelength. The relationship between wavelength and frequency is called an inverse relationship, because as the frequency increases, the wavelength decreases.
 
        
             
        
        
        

Work done = 100J
Distance = 5 meters
Force = ? 

Force = 100/5 = 20N
Therefore, the force needed is 20 Newtons

Wetlands DO NOT increase the rate of extinction of mammals by creating a loss of habitat. Wetlands rather form a habitat for many organisms creating a rich microcosm of an ecosystem. 
Explanation:
Wetlands are land areas that are seasonally or permanently submerged in water. They include marshlands, estuaries, deltas, swamps, floodplains, and etcetera.  The plants within wetlands, such as mangrove slow down water runoff hence allowing settling down of, sediments and pollutants hence ‘cleaning’ the water. 
Due to this fact that wetlands slow water movement, these ecosystems are significant in reducing flooding by ‘storing’ flood water and releasing it slowly hence acting like flood controls.
