An electric transmission line can become coated with ice and the increased diameter may cause vortex formation in prevailing winds. The electric line will oscillate due to the pressure variations, particularly if the frequency of the oscillations is close to one of the resonant frequencies of the wire. The oscillations of long lines may be enough to snap wires or even pull down support poles. If a wire is 347 m long (from pole to pole) and has a tension of 65.2 x 106 N and has a linear density of 3.35 kg/m, (a) find the fundamental mode, and (b) find the frequency difference between successive modes.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
