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.
If (3,2) is (x1,y1), then (7,8) is (x2,y2). 2. Know the distance formula. This formula finds the length of a line that stretches between two points: Point 1 and Point 2. The linear distance is the square root of the square of the horizontal distance plus the square of the vertical distance between two points. More simply put, it is the square root of: (x2âx1)2+(y2ây1)2{\displaystyle (x2-x1)^{2}+(y2-y1)^{2}}. 3. Find the horizontal and vertical distance between the points.
