A string, having a diameter of 1 mm and density of
16.0\times 10^(3)k(g)/(m^(3))
, is fixed at one end. Its other end hangs over a pulley and has a block of mass 3.00 kg attached to it, as shown in Figure 1. The horizontal part has a length of 1.60 m and a mass of 20.0 g . 3.1 Find the tension in the string 3.2 Calculate the linear density of the string 3.3 Determine the speed of a transverse pulse on the string
