Acurrent-carrying wire passes through a region of space that has a uniform magnetic field of 0.92 t. if the wire has a length of 2.6 m and a mass of 0.60 kg, determine the minimum current needed to levitate the wire. a

Oxygen gas enters well-insulated diffuser at 25 lbf/in.2, 420r, with a velocity of 860 ft/s through a flow area of 1.6 in.^2. at the exit, the flow area is 12 times the inlet area, and the velocity is 19 ft/s. the potential energy change from inlet to exit is negligible. assuming ideal gas behavior for the oxygen and steady-state operation of the diffuser, determine the following: (a) the exit temperature, in r(b) the exit pressure, in lbf/in.^2 (c) the mass flow rate, in lb/s

What is "decrease in velocity" i need offering 60 !
