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)

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation
