How might things be different if the airmen had not stood up for their rights? What characteristics of the men were intrinsic to their success in doing so?

Explain how to plot

$$( r , \theta ) \text { if } r < 0 \text { and } \theta > 0$$

The water molecule has an $l=1$ rotational level $1.01\times 10^{-5}$ eV above the $l=0$ ground level. Calculate the wavelength and frequency of the photon absorbed by water when it undergoes a rotational-level transition from $l=0$ to $l=1$. The magnetron oscillator in a microwave oven generates microwaves with a frequency of 2450 MHz. Does this make sense, in view of the frequency you calculated in this problem? Explain.

Draw the structure of an optically inactive fat that, when hydrolyzed under acid conditions, gives glycerol, one equivalent of lauric acid, and two equivalents of stearic acid.

The moment of inertia for CO was calculated. (a) In CO, how far is each atom from the center of mass of the molecule? (b) Use $I=m_1r_1^2+m_2r_2^2$ to calculate the moment of inertia of CO about an axis through the center of mass and perpendicular to the line joining the centers of the two atoms. Does your result agree with the value obtained in Example?

A metalloid a. may conduct electric current. b. can be ductile. c. is also called a semiconductor. d. All of the above

Not all plants have seeds. What advantage do seeds provide a plant?

Find the trigonometric limits in this problem. If you have a graphing calculator or a computer with graphing facility, verify that graphical evidence supports your answer.

$$\displaystyle\lim _{\theta \rightarrow 0} \frac{1-\cos \theta}{\theta \sin \theta}$$

Decide whether the statement is true or false. Give an explanation for your answer. If $\int _ { 0 } ^ { \infty } f ( x ) d x$ and $\int _ { 0 } ^ { \infty } g ( x ) d x$ both converge, then $\int _ { 0 } ^ { \infty } ( f ( x ) + g ( x ) ) d x$ converges.
