The cord of a musical instrument is fixed at both ends and has a length l m, diameter d mm, and density pkg/m3. (a) find the tension required in order to have a fundamental frequency offi hz. (b) determine the velocity of wave propagation, c in the cable. (c) determine the third natural frequencies of vibration of the cable, if tension is increased by 15%. wire lenth, l =2.50m , dia, d =0.8(mm), d =0.0008(m), density=7925(kg/m3), p=0.003983539(kg/m) and f1= 4(hz)

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?
