Three displacements through a hedge maze. (b) the displacement vectors. (c) the first displacement vector and its components. (d) the net displacement vector and its components. d1=6.00 mθ1=40°d2=8.00 mθ2=30°d3=5.00 mθ3=0°,where the last segment is parallel to the superimposed x axis. when we reach point c, what are the magnitude and angle of our net displacement →dnet from point i?

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

As part of an industrial process, air as an ideal gas at 10 bar, 400k expands at steady state through a valve to a pressure of 4 bar. the mass flow rate of air is 0.5 kg/s. the air then passes through a heat exchanger where it is cooled to a temperature of 295k with negligible change in pressure. the valve can be modeled as a throttling process, and kinetic and potential energy effects can be neglected. (a) for a control volume enclosing the valve and heat exchanger and enough of the local surroundings that the heat transfer occurs at the ambient temperature of 295 k, determine the rate of entropy production, in kw/k. (b) if the expansion valve were replaced by an adiabatic turbine operating isentropically, what would be the entropy production? compare the results of parts (a) and (b) and discuss.
