Damage may be a result of the direct effects of alcohol on the brain or may result indirectly, from a poor general health status or from severe liver disease. For example, thiamine deficiency is a common occurrence in people with alcoholism and results from poor overall nutrition.
In the case of a longitudinal wave, a wavelength measurement is made by measuring the distance from a compression to the next compression or from a rarefaction to the next rarefaction. On the diagram above, the distance from point A to point C or from point B to point D would be representative of the wavelength.
To find the point thatâs two-thirds of the distance from (â4,1) to the other endpoint, (8,7): 1  Replace x1 with â4, x2 with 8, y1 with 1, y2 with 7, and k with 2/3. 2  Subtract the values in the inner parentheses. 3  Do the multiplication and then add the results to get the coordinates.
