The curing process of the mentioned example involves exposure of the plate to irradiation from an infrared lamp and attendant cooling by convection and radiation exchange with the surroundings. Alternatively, in lieu of the lamp, heating may be achieved by inserting the plate in an oven whose walls (the surroundings) are maintained at an elevated temperature. Consider conditions for which the oven walls are at $200^{\circ} \mathrm{C}$, airflow over the plate is characterized by $T_{\mathrm{x}}=20^{\circ} \mathrm{C}$ and $h=15 \mathrm{~W} / \mathrm{m}^2 \cdot \mathrm{K}$, and the coating has an emissivity of $\varepsilon=0.5$. What is the temperature of the coating?

Why do volcanoes and earthquakes occur along the Ring of Fire? Think about: tectonic plate movement, movement of magma.

The rectangular plate shown weighs $80 \mathrm{lb}$ and is supported by three vertical wires. Find the tension in each wire.

Show that Eq. holds for a parallel-plate capacitor with a dielectric material between the plates. Use a derivation analogous to that used for Eq.

In what climates does evaporation exceed precipitation?

Assuming that hot spots remain fixed, in what direction was the Pacific plate moving while the Hawaiian islands were forming?

Consider the flow of air at 30 m/s along a flat plate. At what distance from the leading edge will transition occur?

The vertical deflecting plates of a typical classroom oscilloscope are a pair of parallel square metal plates carrying equal but opposite charges. Typical dimensions are about 3.0 cm on a side, with a separation of about 5.0 mm. The potential difference between the plates is 25.0 V. The plates are close enough that we can ignore fringing at the ends. Under these conditions: (a) how much charge is on each plate, and (b) how strong is the electric field between the plates? (c) If an electron is ejected at rest from the negative plate, how fast is it moving when it reaches the positive plate?

Determine the mass moment of inertia of the uniform thin parabolic plate of mass m about the x- axis. State the corresponding radius of gyration.

Describe the difference between a divergent and a convergent plate boundary. Name the geologic features found near each type of boundary.

A right circularly polarized beam is incident on a calcite half-wave plate. Show that the emergent beam will be left circularly polarized.

A parallel-plate capacitor is connected to a power supply that maintains a fixed potential difference between the plates. (a) If a sheet of dielectric is then slid between the plates, what happens to (i) the electric field between the plates, (ii) the magnitude of charge on each plate, and (iii) the energy stored in the capacitor? (b) Now suppose that before the dielectric is inserted, the charged capacitor is disconnected from the power supply. In this case, what happens to (i) the electric field between the plates, (ii) the magnitude of charge on each plate, and (iii) the energy stored in the capacitor? Explain any differences between the two situations.
