The quantities v, k, u, and l all represent physical quantities characterizing the orbit that depend on radius r. indicate the exponent (power) of the radial dependence of the absolute value of each. express your answer as a comma-separated list of exponents corresponding to v, k, u, and l, in that order. for example, -1,-1/2,-0.5,-3/2 would mean v∝r−1, k∝r−1/2, and so forth.
