10) One common kind of computer keyboard is based on the idea of capacitance. Each key is mounted on one end of a plunger, the other end being attached to a movable metal plate (see figure). The movable plate is separated from a fixed plate, the two plates shift forming a capacitor. When the key is pressed, the movable corero option plate is pushed closer to the fixed plate, and the capacitance increases. Electronic Circuitry enables the computer to detect the change in capacitance, thereby recognizing which key has been pressed. The separation between plates when key is Key Plunger pressed is 0.15 x 10³meters. The plate area is 9.50x 10$ m² and Movable metal plate the capacitor is filled with material whose dielectric constant is 3.50. Determine capacitance? Dielectric Fixed metal plate

According to its design specification, the timer circuit delaying the closing of an elevator door is to have a capacitance of 32.0 F between two points A and B. When one circuit is being constructed, the inexpensive but durable capacitor installed between these two points is found to have capacitance 34.8 F. To meet the specification, one additional capacitor can be placed between the two points, (a) Should it be in series or in parallel with the 34.8-F capacitor? (b) What should be its capacitance?

To meet the specification, what additional capacitor should be installed in series or in parallel in that circuit?
If you have ever tried to hang a picture or a mirror, you know it can be difficult to locate a wooden stud in which to anchor your nail or screw. A carpenters stud finder is a capacitor with its plates arranged side by side instead of facing each other as shown in Figure 20.32. When the device is moved over a stud, does the capacitance (a) increase or (b) decrease?
