A 3.0 m long rod has a density described by = a + bx, where is the density in kilograms per meter of length, a = 5.0 kg/m, b = 5.0 kg/m2, and x is the distance in meters from the left end of the rod. The rod rests horizontally with its ends each supported by a scale. What do the two scales read?(adsbygoogle = window.adsbygoogle || []).push({});
