It is possible to calculate the energy of an ocean wave in terms of total energy per unit area of wave ,Ew , using the following equation.
Ew = 1/8 (pgh2)
Where P is the density of water, g is the acceleration due to gravity, and h is the wave height.
Calculate Ew using the appropriate SI units and the following values of p,g and h.
Show all your working and express your answer in scientific notation.
p = 1.03 x 103 kg m-3
g = 9.8 m s -2 Meters per second
H = 145 cm

Ew=(1/8)[1.03kg m^-3*9.8ms^-2*145*10-2m]^2
=(1/8)[214.22](kg/ms)^2
=26.78(kg/ms)^2

If you can't figure out a "Plug 'n Play" problem, you is in *real* deep trouble âº
Ew = (1/8)*(1030 * 9.8 * 1.45 * 2) = 3,659
May the Great Spirit smile upon you when you take your next math exam.
