The wind-chill index is modeled by the function w = 13.12 + 0.6215t â’ 11.37v0.16 + 0.3965tv0.16 where t is the temperature (â°c) and v is the wind speed (km/h). when t = â’19â°c and v = 25 km/h, by how much would you expect the apparent temperature w to drop if the actual temperature decreases by 1â°c?

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.)

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
