Estimate the average power of a water wave when it hits the chest of an adult standing in the water at the seashore. Assume that the amplitude of the wave is 0.56 m , the wavelength is 2.0 m , and the period is 3.4 s . Assume that the area of the chest is 0.14 m^2.

Answer:

[tex]P=45.2W[/tex]

Explanation:

From the question we are told that:

Amplitude [tex]A=0.56m[/tex]

Period [tex]T=3.4s[/tex]

Wavelength [tex]\lambda=2.0[/tex]

Area [tex]a=0.14m^2[/tex]

Generally the equation for Power is mathematically given by

[tex]Power = 2 \pi ^2 \rho a(\frac{\lambda}{T})(\frac{1}{T})*A[/tex]

[tex]P= 2 3.142^2 1025 0.14(\frac{2.0}{3.4})(\frac{1}{3.4})^2*0.56^2[/tex]

[tex]P=45.2W[/tex]
