Provide an example of using precollected data.

What issues in studying society might interfere with following the scientific method precisely?

Quick Write: Use Vivid Language Choose an event discussed in this section. In one or two paragraphs, retell a portion of the event. Be sure to use vivid language and include details. Do additional research if needed.

A CS amplifier has $C_{c 1}=C_{s}=C_{c 2}=1 \mu \mathrm{F}, R_{C}=10 \mathrm{M} \Omega, R_{\mathrm{sg}}=100 \mathrm{k} \Omega, g_{m}=2 \mathrm{mAV}, R_{D}=R_{L}= R_{S}=10 \mathrm{k} \Omega .$ Find $A_{M}, f_{P 1}, f_{P 2}, f_{P 3}, f_{z},$ and $f_{L}.$

Analyze the causes of the looting incidents in New Orleans following Hurricane Katrina. Which of the three theoretical perspectives, would you use to help you understand this behavior? Explain your choice.

A pendulum clock that works perfectly on the Earth is taken to the Moon. If the clock is started at 12:00 midnight, what will it read after one Earth day (24.0 h)? Assume the free-fall acceleration on the Moon is 1.63 m/s$^2$.

How is discrimination different from prejudice?

A cylinder of radius r and height h has volume

$$V = \pi r ^ { 2 } h.$$

(a) Use the linear approximation to show that

$$\frac { \Delta V } { V } \approx \frac { 2 \Delta r } { r } + \frac { \Delta h } { h }$$

(b) Estimate the percentage increase in V if r and h are each increased by 2%. (c) The volume of a certain cylinder V is determined by measuring r and h. Which will lead to a greater error in V: a 1% error in r or a 1% error in h?

What was the sociologist Max Weber referring to when he used the term bureaucracy?

The sympathetic and parasympathetic fibers serve the same organs. How can their opposing effects be explained?

Calculate.$\int_{0}^{a}{\sqrt{a^2-x^2}}dx$

Numbers $n$ such that $\sigma(\sigma(n))=2 n$ are called superperfect numbers. (a) If $n=2^{k}$ with $2^{k+1}-1$ a prime, prove that $n$ is superperfect; hence, 16 and 64 are superperfect. (b) Find all even perfect numbers $n=2^{k-1}\left(2^{k}-1\right)$ which are also superperfect.

The resonant frequency of an RCL circuit is 1.3 kHz , and the value of the inductance is 7.0 mH. What is the reson ant frequency ( in kHz) when the value of the inductance is 1.5 mH?
