When the measure of worth is plotted versus percent change for several parameters, the parameter that is the most sensitive in the economic analysis is the one with the steepest curve (option a).

In economic analysis, sensitivity refers to how responsive one variable is to changes in another variable. When plotting the measure of worth versus percent change, the parameter with the steepest curve indicates a higher degree of sensitivity, as it shows a greater change in the measure of worth for a given change in the percent. This means that small changes in the parameter will have a more significant impact on the overall economic analysis compared to the other parameters with flatter curves.

The most sensitive parameter in economic analysis is the one with the steepest curve when plotting the measure of worth versus percent change.

Answer:

the percentage of light that gets through this combination is 9.38

Explanation:

Given the data in the question;

Let us represent the incident unpolarized light with \(I_0\).

So, the amount of light intensity passing through the first polarizer will be;

\(I_1\) = \(I_0\) / 2 ------ let this be equation 1

An the amount of light intensity passing through the second polarizer will be;

\(I_2\) = \(I_1\)cos²θ

given that; the second one has its transmission axis at 30°

so, we substitute;

\(I_2\) = \(I_1\) × cos²( 30° )

\(I_2\) = \(I_1\) × 0.75

\(I_2\) = 0.75\(I_1\)

from equation; \(I_1\) = \(I_0\) / 2

\(I_2\) = 0.75( \(I_0\) / 2 )

\(I_2\) = 0.375\(I_0\) .

Now, the amount of light intensity passing through the third polarizer will be;

\(I_3\) = \(I_2\)cos² ( 90° - 30° )

\(I_3\) = \(I_2\) × cos²( 60° )

\(I_3\) = \(I_2\)  × 0.25

we substitute

\(I_3\) = 0.375\(I_0\)  × 0.25

\(I_3\) = 0.09375\(I_0\)

∴ \(I_3\)/\(I_0\) × 100 = 0.09375 × 100

⇒ 9.38%

Therefore, the percentage of light that gets through this combination is 9.38

When an ordinarily elastic material cracks brittlely, there is little or no outward trace of material deformation prior to failure.

The plastic deformation that occurs before failure is minimal or nonexistent in brittle fractures. Glasses, ceramics, as well as various polymers and metals, frequently fracture in a brittle way.

When a material is exposed to forces below its yield limit, brittle fractures take place. A ductile material is typically the foundation for machine design, and the design criteria are intended to prevent plastic and, in some circumstances, elastic deformations.

Material that has undergone either no plastic deformation or very little plastic deformation prior to fracture is said to have fractured with brittleness. Since they all share this quality, brittle materials include rock, concrete, glass, and cast iron.

The secondary side of the transformer has 80 turns.

A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. It consists of two or more coils of wire, known as windings, that are linked by a magnetic core. The primary winding is connected to the input voltage source, while the secondary winding is connected to the output circuit.

In this case, we have a 120/24 volt transformer with 400 turns on the primary side. The turns ratio of a transformer is determined by the ratio of the number of turns on the primary winding to the number of turns on the secondary winding. To find the number of turns on the secondary side, we can use the turns ratio.

The turns ratio is calculated as follows:

Turns ratio = Number of turns on primary side / Number of turns on secondary side

In this case, the turns ratio is:

Turns ratio = 400 / X (unknown number of turns on the secondary side)

Given that the transformer has a voltage ratio of 120/24 volts, we can also use the voltage ratio to find the turns ratio:

Turns ratio = Voltage ratio = 120 / 24

By substituting the known values into the equation, we can solve for X, the number of turns on the secondary side:

400 / X = 120 / 24

Cross-multiplying and solving for X, we get:

X = (400 * 24) / 120 = 80 turns

Therefore, the secondary side of the transformer has 80 turns.

The chord length of the F-22 where the wing joins the center body is 21.5 ft.

If the airplane is making a high-speed pass at a velocity of 1398 ft/s at sea level (Mach 1.2),

the Reynolds number at the wing root can be calculated as follows:

The formula for calculating the Reynolds number is given by:

Re = rho * v * c / µ

where,

ρ = Density of air (at sea level) = 1.225 kg/m

3v = Velocity of aircraft = 1398 ft/s

c = Chord length of wing = 21.5 f

t = 6.5532

µ = Dynamic viscosity of air (at sea level) = 1.789 * 10^-5 Pa s (approx.)

We need to convert the values to S.I. units before we can apply them in the formula.

Rho = 1.225 kg/m

3v = 427.2 m/s

c = 6.5532 ft = 1.997 mµ = 1.789 * 10^-5 Pa s

Now we can substitute the values in the formula and simplify as follows:

Re = rho * v * c / µ= (1.225 kg/m3) * (427.2 m/s) * (1.997 m) / (1.789 * 10^-5 Pa s)= 1.015 * 10^7

This is the Reynolds number at the wing root. Rounding off to two decimal places gives a final answer of 10,150,000.

the Reynolds number at the wing root is 10,150,000.

Answer:

The resistance of the flow of charges in an electric circuit (electrical resistance) is analogous to the frictional effect between water flow through a pipe and the pipe's surface

Explanation:

In comparison to its similarity to the diameter of the pipe affects the flow of water and acts a a factor affecting resistance so are there factors affecting electrical resistance.

in an electrical circuit:

the total length of the wire is to the length of a pipe of water

the cross-sectional area of the wire is to the diameter of a pipe of water.

Thus, the cross sectional are affects the amount of electrical resistance. Wider wires have wider cross-sectional area and vice versa. Also, water will flow (i.e. current) through a wider pipe (i.e. large diameter) at a faster rate than a narrow pipe (i.e. small diameter). This is due to the lower amount of resistance offered by the wider pipe.

in the same manner, the wider the wire, the lesser the electrical resistance to the flow of elsctric charge and vice versa for thiner wires.

The cdf of the amount of time a book on two-hour reserve is actually checked out can be represented by the function F(x) = P(X ≤ x), where X is the random variable representing the amount of time the book is checked out and x is a specific value of time.

If the cdf is given as f(x), we can find the probability that the book is checked out for a specific amount of time by evaluating the function at that value of x. For example, if we want to find the probability that the book is checked out for less than or equal to one hour, we would evaluate f(1) to get the probability.

Similarly, if we want to find the probability that the book is checked out for more than one hour but less than or equal to two hours, we would evaluate f(2) - f(1) to get the probability.

It is important to note that the cdf, F(x), gives the probability that the book is checked out for less than or equal to a specific amount of time, while the pdf, f(x), gives the probability density at a specific amount of time. The pdf can be found by taking the derivative of the cdf, F'(x) = f(x).

In the frontal plane, the muscles that are agonist to each other during eccentric actions are the muscles on opposite sides of the plane, specifically the muscles on the left and right sides of the body.

The frontal plane divides the body into anterior (front) and posterior (back) sections. When performing eccentric actions in the frontal plane, muscles on opposite sides of the body are typically engaged in an agonist-antagonist relationship. An agonist muscle is the muscle primarily responsible for producing a specific movement, while the antagonist muscle opposes or relaxes to allow the movement to occur.

For example, in the frontal plane, the muscles on the left side of the body would be agonists to the muscles on the right side, and vice versa. When performing eccentric actions, such as lowering a weight or resisting against a force, the muscles on one side of the body contract eccentrically to control the movement, while the muscles on the opposite side lengthen eccentrically. This creates a balanced and coordinated movement in the frontal plane, with the muscles on one side acting as agonists and the muscles on the opposite side acting as antagonists to allow controlled movement and stability

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.
