Adog named rascal leaves his home and travels a short distance and then returns home. the graph shows his position as a function of time.
how does his velocity on his return trip compare to his velocity for the first 5 seconds?
a) his velocity was slower when compared to the first 5 seconds.
b) his velocity was positive on the return trip when compared to the first 5 seconds.
c) his velocity on the return trip was twice as slow when compared to the first 5 seconds.
d) his velocity on the return trip was twice as fast when compared to the first 5 seconds.

What type of electromagnetic wave is used in security pens? a. x-rays c. microwaves b. visible light d. ultraviolet radiation select the best answer from the choices provided

Two horizontal plates with infinite length and width are separated by a distance h in the z direction. the bottom plate is moving at a velocity u. the incompressible fluid trapped between the plates is moving in the positive x-direction with the bottom plate. align gravity with positive z. assume that the flow is fully-developed and laminar. if the systems operates at steady state and the pressure gradient in x-direction can be ignored, do the following: 1. sketch your system 2. identify the coordinate system to be used. 3. show your coordinates and origin point on the sketch. list all your assumptions. 5. apply the continuity equation to your system. nts of navier stokes equations of choice to your system 7. solve the resulting differential equation to obtain the velocity profile within the system make sure to list your boundary conditions. check units of velocity 8. describe the velocity profile you obtain using engineering terminology. sketch that on the same sketch you provided in (1). 9. obtain the equation that describes the volumetric flow rate in the system. check the units.
