5. Normal functioning of a lamp Official 2018 - A series circuit is composed of a generator (G) that maintains across its terminals a constant voltage
0-24 V, an ammeter (A) of negligible resistance, a resistor (D) of resistance R, and a lamp (L)
considered as a resistor and carrying the indications (9W; 18V). In this circuit, (L) is functioning normally.
1. Draw a diagram of the above circuit.
2. What does each of the indications carries by (L) represent?
3. Show that the current through (L) is I 0.5A.
4. Deduce the value of the resistance R of (L).
5. 5.1. Calculate the voltage across (D).
5.2. Deduce the value of R.
6. We replace (D) by a connection wire.
6.1. What is the new voltage across (L)?
6.2. (L) may bum out. Why?
6.3. What was then the role of (D)?

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.

To do work, this truck uses energy stored in chemical fuel and an electrical battery. how much total energy does this truck put out?

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude
