Which of the following statements best explains why the homogeneity of a physical equation is not a sufficient condition for the correctness of the equation? For an equation to be homogenous the A units of the physical quantities on both sides of the equation must be equal. All correct equations are homogenous but 1. B not all homogenous equations are correct. A homogenous equation may contain a C wrong unit less constant. Homogeneity can be used to test the D relationship between quantities in a physical equation.

Please teach how to solve not just solve Now suppose: Z₁ = y₁ + 2y3 Z2 = 2y1 + 3y2 - Y3 Z3 = y₁ + y₂ Y₁ = x3 Y/₂ = 2x₂ + x3 Y3 = x₁ + 3X₂ X3 Express x₁ in terms of Z₁, Z2, Z3; x₂ in terms of Z₁, Z2, Z3; and x3 in terms of 2₁, 22, 23. Be sure to state all assumptions and do and show essential calculations. Consider the following matrices: X = a) Verify that (XY)' = Y'X' b) True or false: tr[X + Y] = tr[X] + tr[Y]? c) True or false: tr[XY] = tr[YX]? (X₁1X12),X = X224 Y21 22-
