A uniform flexible steel cable of weight $m g$ is suspended between two points at the same elevation as shown in given Fig., where $\theta=56^{\circ}$. Determine the tension in the cable at its lowest point.

Two identical objects are pressed against two different springs so that each spring stores $50 \mathrm{~J}$ of potential energy. The objects are then released from rest. One spring is quite stiff (hard to compress), while the other one is quite flexible (easy to compress). Which of the following statements is or is true? (More than one statement may be true.)
A. Both objects will have the same maximum speed after being released.
B. The object pressed against the stiff spring will gain more kinetic energy than the other object.
C. Both springs are initially compressed by the same amount.
D. The stiff spring has a larger spring constant than the flexible spring.
E. The flexible spring must have been compressed more than the stiff spring.

The system of small objects is rotating at an angular speed of $2.0 \mathrm{rev} / \mathrm{s}$. The objects are connected by light, flexible spokes that can be lengthened or shortened. What is the new angular speed if the spokes are shortened to $0.50 \mathrm{~m}$ ? (An effect similar to that illustrated in this problem occurred in the early stages of the formation of our galaxy. As the massive cloud of dust and gas that was the source of the stars and planets contracted, an initially small angular speed increased with time.)

Using a chart like the one displayed, list the sensory images used in "Runagate Runagate." Discuss how the words you have listed demonstrate the theme that a journey on the Underground Railroad was full of risk, danger, reward, and emotion.

A soldier can hide in one of five foxholes (1, 2, 3, 4, or 5). A gunner has a single shot and may fire at any of the four spots A, B, C, or D. A shot will kill a soldier if the soldier is in a foxhole adjacent to the spot where the shot was fired. For example, a shot fired at spot B will kill the soldier if he is in foxhole 2 or 3, while a shot fired at spot D will kill the soldier if he is in foxhole 4 or 5. Suppose the gunner receives a reward of 1 if the soldier is killed and a reward of 0 if the soldier survives the shot. a. Assuming this to be a zero-sum game, construct the reward matrix. b. Find and eliminate all dominated strategies. c. We are given that an optimal strategy for the soldier is to hide ļ of the time in foxholes 1, 3, and 5. We are also told that for the gunner, an optimal strategy is to shoot $\frac{1}{3}$ of the time at A, $\frac{1}{3}$ of the time at D, and $\frac{1}{3}$ of the time at B or C. Determine the value of the game to the gunner. d. Suppose the soldier chooses the following nonoptimal strategy: $\frac{1}{2}$ of the time, hide in foxhole 1; $\frac{1}{4}$ of the time, hide in foxhole 3; and $\frac{1}{4}$ of the time, hide in foxhole 5. Find a strategy for the gunner that ensures that his expected reward will exceed the value of the game. e. Write down each player’s LP and verify that the strategies given in part (c) are optimal strategies.

b. reward
c. criticize

A philanthropist writes a positive number x on a piece of red paper, shows the paper to an impartial observer, and then turns it face down on the table. The observer then flips a fair coin. If it shows heads, she writes the value 2x and, if tails, the value x/2, on a piece of blue paper, which she then turns face down on the table. Without knowing either the value x or the result of the coin flip, you have the option of turning over either the red or the blue piece of paper. After doing so and observing the number written on that paper, you may elect to receive as a reward either that amount or the (unknown) amount written on the other piece of paper. For instance, if you elect to turn over the blue paper and observe the value 100, then you can elect either to accept 100 as your reward or to take the amount (either 200 or 50) on the red paper. Suppose that you would like your expected reward to be large. (a) Argue that there is no reason to turn over the red paper first, because if you do so, then no matter what value you observe, it is always better to switch to the blue paper. (b) Let y be a fixed nonnegative value, and consider the following strategy: Turn over the blue paper, and if its value is at least y, then accept that amount. If it is less than y, then switch to the red paper. Let

$$R_y(x)$$

denote the reward obtained if the philanthropist writes the amount x and you employ this strategy. Find

$$E \left[ R _ { y } ( x ) \right]$$

. Note that

$$E \left[ R _ { 0 } ( x ) \right]$$

is the expected reward if the philanthropist writes the amount x when you employ the strategy of always choosing the blue paper.

An inflated rubber balloon filled with air is immersed in a flask of liquid nitrogen that is at $77 \mathrm{~K}$. Describe what happens to the balloon, assuming that it remains flexible while being cooled.

Propose some confounding variables that the researcher might want to consider when doing a study.

A leading journal reported that people who have a more flexible work schedule are more satisfied with their jobs.

A clever courtier, offered a reward by an ancient king of Persia, asked for a grain of rice on the first square of a chess board, 2 grains on the second square, then 4,8,16, and so on.

How many grains of rice should the king deliver for the 64th (and final) square?

Accenture’s Defining Success global research study found that the majority of today’s working women would prefer a better work–life balance to an increased salary. One of the most important contributors to work–life balance identified by the survey was “flexibility,” with 80% of women saying that having a flexible work schedule is either very important or extremely important to their career success. Suppose you select a sample of 100 working women.

a. What is the probability that in the sample fewer than 85% say that having a flexible work schedule is either very important or extremely important to their career success?

b. What is the probability that in the sample between 75% and 85% say that having a flexible work schedule is either very important or extremely important to their career success?

c. What is the probability that in the sample more than 82% say that having a flexible work schedule is either very important or extremely important to their career success?

d. If a sample of 400 is taken, how does this change your answers to (a) through (c)?

A 1.00-mole sample of naphthalene (mothballs) is placed in a flexible, sealed container and allowed to sublime. After complete sublimation, what will be the container volume, in liters, at $33^o\text{C}$ and 1.183 atm pressure?
