In the figure, an aluminum wire, of length L₁= 366 cm, cross-sectional area 4.00x102 cm², and density 2.60 g/cm³, is joined to a steel wire of density 7.80 g/cm³ and the same cross-sectional area. The compound wire, loaded with a block of mass m= 7.50 kg, is arranged so that the distance from the joint to the supporting pulley is L₂= 352 cm. Transverse waves are set up on the wire by an external source of variable frequency; node is located at the pulley. Li Aluminium -L₂ Steel m Find the lowest frequency that generates a standing wave having the joint as one of the nodes. Submit Answer Tries 0/10 How many nodes are observed at this frequency?
