A parallel circuit has a resistance of 280 and an inductive reactance of 360 02. What's this circuit's impedance?

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)
