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.
distance formula for polar coordinates See figure 6 on p. 579. Let's find the distance between two points in the polar coordinate system. We can make a triangle by drawing the line segment connecting the two points. Then by using the Law of Cosines, we can find the distance between the two points. ! d 2 =r 12 +r 22 2r 1 r 2 cos(# 2 # 1) .
