Using the data given in Table, calculate the thickness of the quartz half-wave plate for $\lambda_0=5890 \text{\AA}$.

Under what conditions can the outer surface of a vertical cylinder be treated as a vertical plate in natural convection calculations?

A 3-in-diameter horizontal jet of water, with velocity 140 ft/s, strikes a bent plate, which deflects the water by; $135^{\circ}$ from its original direction. How much force is required to hold the plate against the water stream and what is its direction? Disregard frictional and gravitational effects.

Find the number of possible license plate numbers (with no letters or digits excluded) for each of the following conditions:

6 digits

Determine the mass of inertia about the y-axis for the parabolic plate of the previous problem. State the radius of gyration about the y-axis.

It takes 100,000 years for a plate to move about 2 kilometers. What is the rate of motion in centimeters per year?

Repeat the above problem for the plates oriented in a horizontal position with the $50^{\circ} \mathrm{C}$ surface as the lower plate.

Find the centroid of a thin, flat plate covering the region enclosed by the x-axis, the lines x = 2 and x = -2, and the parabola $y=x^{2}.$

A parallel-plate capacitor has circular plates of 8.20 cm radius and 1.30 mm separation. (a) Calculate the capacitance.

A $0.40~\mu \mathrm{F}$ capacitor is connected to a $9.0~ \mathrm{V}$ battery. How much charge is on each plate of the capacitor?

Find the center of mass of a plate that is shaped like the region between $y = x^2$ and $y = 2x$, where the density varies as $1 + x + y.$

A vertical flat plate is maintained at a constant temperature of $120^{\circ} \mathrm{F}$ and exposed to atmospheric air at $70^{\circ} \mathrm{F}$. At a distance of $14\ \mathrm{in}$. from the leading edge of the plate the boundary layer thickness is $1.0\ \mathrm{in}$. Find the thickness of the boundary layer at a distance of $24\ \mathrm{in}$. from the leading edge.
