The running time of the algorithm is O(N^4), because there are four nested loops, each of which runs for N iterations.

(a) Define the entries of your table in words:

T(i, j, k) is the minimum total cost of a flight schedule that gets you from city i to city j in exactly k days.

(b) State recurrence for entries of table in terms of smaller subproblems:

T(i, j, k) = min { T(i, l, k-1) + c[l][j] } for all l in {1, ..., N}

This means that the minimum total cost of a flight schedule from city i to city j in exactly k days is the minimum of the total cost of a flight schedule from city i to city l in k-1 days plus the cost of a direct flight from city l to city j, for all possible intermediate cities l.

(c) Write pseudocode for your algorithm to solve this problem:

```
// Initialize the table with infinity for all entries
for i in {1, ..., N}:
 for j in {1, ..., N}:
   for k in {1, ..., N}:
     T(i, j, k) = infinity

// Base case: the cost of a direct flight from city i to city j in 1 day is c[i][j]
for i in {1, ..., N}:
 for j in {1, ..., N}:
   T(i, j, 1) = c[i][j]

// Fill in the table using the recurrence
for k in {2, ..., N}:

     for l in {1, ..., N}:
       T(i, j, k) = min(T(i, j, k), T(i, l, k-1) + c[l][j])

Neither A nor B, as the secondary shoe of a duo servo drum brake has 70% greater braking power than the primary shoe.

The secondary shoe has more lining than the primary shoe since it handles the majority of the braking.

Drum brakes are still often utilised on the rear axles of modern automobiles and are ubiquitous on classic cars. The duo-servo drum break, self-adjusting drum brake can produce as much stopping force as a disc brake and will give many, many miles of maintenance-free driving, even though disc brakes are easier to use and more resistant to heat fade.

Duo-servo drum brake systems have a pair of brake shoes connected by an adjuster at the bottom and a hydraulic wheel cylinder towards the top. Above the wheel cylinder, the highest tips of the shoes rest against an anchor pin.

The net work done by the Nitrogen in lifting the mass and the pressure is; W_n = 0.6257 kJ

We are given;

Mass of argon; m_a = 0.1 kg

mass of piston; m_p = 5 kg

Pressure 1; p₁ = 100 kPa

Temperature 1; T₁ = 300 K

Temperature 2; T₂ = 320 K

Ideal gas constant; R = 0.208 kJ/kg.K

γ = 1.67

Since the reaction is adiabatic and slowly reversible, then we will use the formula; PV^(γ) = C

Thus, work done by argon is;

W_ar = [m_a * R(T₁ - T₂)]/(γ - 1)

W_ar = [0.1 * 0.208(300 - 320)]/(1.67 - 1)

W_ar = -0.6028 kJ

Work done by nitrogen will be;

W_n = |W_ar| + (m_p * g * m_a)/1000

Answer:

D) AND gate.

Explanation:

Given that:

A certain printer requires that all of the following conditions be satisfied before it will send a HIGH to la microprocessor acknowledging that it is ready to print

These conditions are:

1. The printer's electronic circuits must be energized.

2. Paper must be loaded and ready to advance.

3. The printer must be "on line" with the microprocessor.

Now; if these conditions are met  the logic gate produces a HIGH output indicating readiness to print.

The objective here is to determine the basic logic gate used in this circuit.

Now;

For NOR gate;

NOR gate gives HIGH only when all the inputs are low. but the question states it that "a HIGH is generated and applied to a 3-input logic gate". This already falsify NOR gate to be the right answer.

For NOT gate.

NOT gate operates with only one input and one output device but here; we are dealing with 3-input logic gate.

Similarly, OR gate gives output as a high if any one of the input signals is high but we need "a HIGH that is generated and applied to a 3-input logic gate".

Finally, AND gate output is HIGH only when all the input signal is HIGH and vice versa, i.e AND gate output is LOW only when all the input signal is LOW. So AND gate satisfies the given criteria that; all the three conditions must be true for the final signal to be HIGH.

To implement a Java method sumArray that returns the sum of the values in a given double array, you can write the following code.

This method takes in a double array as its parameter and initializes a variable called "sum" to zero. It then iterates through the array using a for loop, adding each value in the array to the sum. Finally, it returns the total sum of the values in the array. The sumArray method starts by creating a variable called "sum" and setting it equal to zero. This variable will be used to keep track of the total sum of the array values. For each index in the array, the method adds the value at that index to the "sum" variable using the += operator. This will accumulate the sum of all the values in the array.

```java
public static double sumArray(double[] a) {
   double sum = 0;
   for (int i = 0; i < a.length; i++) {
       sum += a[i];
   }

The amount of steel you would expect to have per square foot of building space in an 8-story office building is 10 psf.

In an 8-story office building, the weight of steel per square foot of building space can vary depending on the design and construction specifications. However, as a general guideline, a typical steel-framed office building would have around 10 pounds of steel per square foot of building space. This includes the weight of structural steel columns, beams, and other components necessary to support the building's weight and provide structural integrity.

It's important to note that the actual weight of steel can vary based on factors such as the building's design, height, and intended use. Therefore, it's always recommended to consult with a structural engineer or architect for a more precise estimation based on the specific requirements of your project.

A subcritical refrigeration cycle is a type of refrigeration cycle that operates below the critical point of the refrigerant. The critical point is the temperature and pressure at which the refrigerant transitions between the liquid and gas phases without any distinction between them.

In a subcritical cycle, the refrigerant remains in the liquid phase during the entire cycle.

The four processes involved in a subcritical refrigeration cycle are:

Compression: The refrigerant enters the compressor as a low-pressure vapor and is compressed to a higher pressure and temperature.

Condensation: The compressed refrigerant flows into the condenser, where it releases heat to the surroundings and changes from a high-pressure vapor to a high-pressure liquid.

Expansion: The high-pressure liquid refrigerant enters the expansion valve or throttle valve, where its pressure is reduced, causing it to partially vaporize and cool.

Evaporation: The partially vaporized refrigerant flows into the evaporator, where it absorbs heat from the surrounding environment, completing the cooling process. The refrigerant then returns to the compressor to start the cycle again.

In a subcritical refrigeration cycle, the cooling effect is achieved through the evaporation of the refrigerant in the evaporator, while the condenser rejects heat to the surroundings.

If an engine fails during rollout or just before takeoff, immediately shut both throttles and land the aircraft safely. Before reaching a safe single engine speed right away after takeoff, drop your nose to increase velocity.

Closing the throttle, turning off the fuel pump, setting the mixture control to idle cutoff, and simply cranking the engine is the most reliable hot start method I've found.

If an engine fails during rollout or just before takeoff, immediately shut both throttles and land the aircraft safely. Before reaching a safe single engine speed right away after takeoff, drop your nose to increase velocity. If you are unable to climb, close both throttles and land straight ahead.

The typical practice for the majority of aircraft would be to abandon takeoff if an engine failed during takeoff. In small aircraft, the pilot should turn the throttles down to idle, activate the speed brakes (if provided), and apply the brakes as needed if the engine fails before VR (Rotation Speed).

To calculate the force that the biceps must exert to hold a 600 g ball at the end of a forearm that has a mass of 1.00 kg and is parallel to the floor, we can use the principles of torque and equilibrium.

First, we need to calculate the torque of the forearm due to its weight, which is acting at its center of mass (which we can assume is at the midpoint of the forearm). The weight of the forearm can be calculated as W_forearm = m_forearm * g, where m_forearm = 1.00 kg is the mass of the forearm and g = 9.81 m/s^2 is the acceleration due to gravity. The distance from the elbow to the midpoint of the forearm is L_forearm/2 = 17.5 cm, or 0.175 m. Therefore, the torque due to the weight of the forearm is:τ_forearm = W_forearm * L_forearm/2 = (1.00 kg * 9.81 m/s^2) * 0.175 m = 1.71 NmNext, we need to calculate the torque due to the weight of the ball, which is acting at a distance of dball = 37.0 cm from the elbow. The weight of the ball can be calculated as W_ball = m_ball * g, where m_ball = 0.600 kg is the mass of the ball. Therefore, the torque due to the weight of the ball is:τ_ball = W_ball * dball = (0.600 kg * 9.81 m/s^2) * 0.370 m = 2.24 NmFinally, we need to calculate the force that the biceps must exert to hold the ball at equilibrium, i.e. when the torque due to the weight of the forearm is equal and opposite to the torque due to the weight of the ball. Since the torque due to a force is τ = F * d, where F is the force and d is the distance from the point of application of the force to the pivot point (which is the elbow in this case), we can write:F_biceps * d_biceps = τ_ball - τ_forearmwhere d_biceps = 3.50 cm = 0.035 m is the distance from the elbow to the point where the biceps is attached to the forearm. Substituting the values for τ_ball and τ_forearm, we get:
