How is the color shift referenced above related to the motion of galaxies?
a) red light travels faster so it reaches earth from distant galaxies before other light waves.
b) red light has a higher frequency so these are the only waves able to reach earth from distant galaxies.
c) red light has longer wavelengths so these are the only waves of the visible spectrum that are able to reach earth without interference.
d) red light has longer wavelengths so light waves from galaxies traveling away from earth appear to shift to the red end of the visible spectrum.

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.
