The Spanish Civil War ended more than 65 years ago. What value is there in reading Hemingway's article today? What insights about war does it provide?

For liquid-in-glass thermometers, the thermomerric property is the change in length of the thermometer liquid with temperature. However, other effects are present that can affect the temperature reading of such thermometers. What are some of these?

A $20^{\circ}$ inclined manometer attached to a piezometer opening is used to measure the pressure at the wall of airflow. If the reading is measured to be $4 \mathrm{~cm}$ of mercury, calculate the pressure at the wall.

What similarities in style and theme do you see in "A New Kind of War" and "In Another Country," the Hemingway short story on page 970 ?

A company is producing and marketing new reading activities for elementary school children that it believes will improve reading comprehension scores. A researcher randomly assigns third graders to an eight-week program where some will use these activities and others will experience traditional teaching methods. At the end of the experiment, both groups take a reading comprehension exam. Their scores are displayed in the back-to-back stem-and-leaf display. Do these results indicate that the new activities are better? Test a suitable hypothesis and state your conclusion.

A gasoline line is connected to a pressure gage through a double-U manometer, as shown in the figure. If the reading of the pressure gage is $260\ \mathrm{kPa}$, find the gage pressure of the gasoline line.

Which of the following is an example of a social-cultural influence on aggressive behavior? a. Reading an anxiety-provoking novel. b. Frustration. c. Testosterone. d. Exposure to violent media. e. Genetics.

Blood pressure is given by two numbers written as a fraction: $\frac { \text { systolic } } { \text { diastolic } }$ The systolic reading is the maximum pressure in an artery, and the diastolic reading is the minimum pressure in an artery. As the heart beats, the systolic measurement is taken; when the heart rests, the diastolic measurement is taken. A reading of $\frac { 120 } { 80 }$ is considered normal. Your pulse is the number of heartbeats per minute. Suppose Desmond's blood pressure after t minutes is given by $p ( t ) = 20 \sin ( 140 \pi t ) + 122$ where p ( t ) is the pressure in millimeters of mercury. a. Find the period and explain how it relates to pulse. b. Graph the function p over one period. c. What is Desmond's blood pressure?

There are 7 books numbered 1–7 on the summer reading list. Peter randomly chooses 2 books. What is the probability that Peter chooses books numbered 1 and 2?

In Figure 4-45, the objects are attached to spring scales calibrated in newtons. Give the reading(s) of the balance(s) in each case, assuming that both the scales and the strings are massless.

Fill each blank with the correct form of good, well, bad, or badly.
Consuelo found that reading others’ manuscripts helped her to recognize the _____spots in her own work.

An infrared LED is optically coupled to a photodiode. When the LED is turned off, the reading on an ammeter in series with the reverse-biased photodiode will (a) not change, (b) decrease, (c) increase, (d) fluctuate.

A thermometer reading $72^{\circ} \mathrm{F}$ is placed in a refrigerator where the temperature is a constant $38^{\circ} \mathrm{F}$. Using a graphing utility, graph the relation between temperature and time.

If the distance from the lens in your eye to the retina is $19.0 \mathrm{~mm}$, what is the focal length of the lens when reading a sign $40.0 \mathrm{~cm}$ from the lens?
