A baby crawls toward a toy. Its motion is shown on the following graph of horizontal position xxx vs. time ttt. Graph of x (in meters) vs. t (in seconds). The y-intercept is at 1 m, and the straight line also intersects (4, 2) and (8, 3). Graph of x (in meters) vs. t (in seconds). The y-intercept is at 1 m, and the straight line also intersects (4, 2) and (8, 3). What is the average speed of the baby between the times t=0\text{ s}t=0 st, equals, 0, start text, space, s, end text and t=4\text{ s}t=4 st, equals, 4, start text, space, s, end text?

If you mix chlorine lithium in nickel together which two elements would be the most reactive

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.
