A slight change in the example circuitIf you inadvertently made any changes to the example circuit, reload example. cir. Now we will experiment with changing the OR gate to an AND gate. First, it will help to keep track of where the gates are by locating them within a rectangular grid. To display the grid, select On from the Grid menu. Then choose Delete from the Changes menu. Now you can delete any gate or switch in your circuit by clicking it. Click the OR gate. The gate together with the lines coming into it should disappear. Next, select the AND gate from the Gates menu. Click in the area previously occupied by the OR gate. You should see an AND gate appear in the grid cell where you clicked.

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.

Explain why electric current cannot exist if a current doesn't have a voltage source.
