Awave with a height of 10 feet and wavelength of 20 feet has a wave base of

10 ft

The wave base of a wave is the depth at which there is no more perturbation of the medium caused by the wave. The wave base of a wave is determined to be half the wavelength of the wave itself.

Therefore;

Wave base = wavelength/2

                   = 20 ft/2

                  = 10 ft

10 feet

Explanation: I got it right on the test (Apex)

distance, luminosity, brightness, radius, chemical composition, and temperature

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
