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.
Question: Find the distance between the skew lines L 1 and L 2 whose parametric equations are given as follows: L 1: x = 1 + 2t, y = 3t and z = 2 - t. L 2: x = -1 + s, y = 4 + s, z = 1 + 3s. Solution: Step 1: Finding equation of a plane containing the line L2.
