5. [RC Circuits] Consider the circuit shown in Figure 5 attached. As shown, the switch is in position "A" for t < 0, and the circuit has been at rest for a long time. At time t = 0, the switch opens and the capacitor starts to drain across the resistor. (a) When the switch is closed and there is only a direct current (DC) source, the capacitor acts like an open circuit. Find the constant voltage across the capacitor...

1. Shown above are two different circuits. Each circuit is made
out a battery, a capacitor, a switch, and two resistors. All the
components (batteries, switches, capacitors, and resistors) are
identical in the above circuits. For both circuits, when the switch
is closed, the capacitors will get charged. Which of the following
is correct about the peak current in the circuit?
- Circuit B has 4 times larger peak current than circuit A.
- Circuit B has 2 times larger...

Consider our standard coax cable as an “infinite” length wire of
radius a surrounded by a thin conducting cylinder, coaxial with the
wire, with inner radius b and outer radius c. Again, assume
ab and cbb (thin shell and wire), as show in the
figure.
We now want to investigate energy flow in the same cylindrical
coax cable defined above. However, for now, let’s just look at
fields constant in time, not varying in time. Assume that constant
current I...

Two uniform light bars BD and DC are pinned together at D, where a cable is also attached as shown in the figure below
Two uniform light bars BD and DC are pinned together at D, where a cable is also attached as shown in the figure below. The bars are connected to the reference frame at B and C by smooth ball joints. The system supports the 300 lb force pulling at D in the negative x direction. Find the force in the cable, and the reactions at B and C. The bars are in the yz plane.

2. (15 scores) Consider the mechanical system shown in Figure 1. A spring exerts a force that is a function of its extension. A damper exerts a force that is a function of the velocity of the piston. Assume that the spring and the damper are both linear. (1) We want to describe the relation between the external force F(t) and the position yt) of the mass. Give the differential equation relating F(t) and y(t). Define this carefully as a...

of the electric circuit and run the same (but unknown) current
