We’ve all heard about them, and we all have our fears. For everyday Internet users, computer viruses are one of the most common threats to cyber security. Statistics show that approximately 33% of household computers are affected with some type of malware, more than half of which are viruses.

Rogue security software is malicious software that mislead users to believe there is a computer virus installed on their computer or that their security measures are not up to date. Then they offer to install or update users’ security settings. They’ll either ask you to download their program to remove the alleged viruses, or to pay for a tool. Both cases lead to actual malware being installed on your computer.

Metaphorically, a “Trojan horse” refers to tricking someone into inviting an attacker into a securely protected area. In computing, it holds a very similar meaning — a Trojan horse, or “Trojan,” is a malicious bit of attacking code or software that tricks users into running it willingly, by hiding behind a legitimate program.

By “adware” we consider any software that is designed to track data of your browsing habits and, based on that, show you advertisements and pop-ups. Adware collects data with your consent — and is even a legitimate source of income for companies that allow users to try their software for free, but with advertisements showing while using the software. The adware clause is often hidden in related User Agreement docs, but it can be checked by carefully reading anything you accept while installing software. The presence of adware on your computer is noticeable only in those pop-ups, and sometimes it can slow down your computer’s processor and internet connection speed.

Computer worms are pieces of malware programs that replicate quickly and spread from one computer to another. A worm spreads from an infected computer by sending itself to all of the computer’s contacts, then immediately to the contacts of the other computers.

The Answers for the given question are as follow:

a. The model speed is approximately 31.62 rev/min.

b. The scale ratio is approximately 0.0417.

c. The estimated volume flow rate through the model is approximately 943.44 m^3/s.

d. The bearing thrust of the model is approximately 9.72 kN.

To calculate the required values for the water turbine model, we can utilize the concept of dynamic similarity.

a. To find the model speed, we can use the principle of geometric similarity, which states that the ratio of speeds is equal to the ratio of the square roots of the head. Thus:

  Model speed = (√(Model head))/(√(Full-size head)) * Full-size speed

              = (√4.9/√16.5) * 93.7 rev/min

              = 31.62 rev/min

b. The scale ratio can be determined using the equation:

  Scale ratio = (√(Model power))/(√(Full-size power))

             = (√37.5kW)/(√27MW)

             ≈ 0.0417

c. To estimate the volume flow rate through the model, we can use the power equation:

  Model power = (Model efficiency) * (Volume flow rate) * (Model head) * (Gravity)

  37.5kW = 0.88 * (Volume flow rate) * 4.9m * (9.81m/s^2)

  Solving for the volume flow rate:

  Volume flow rate = 37.5kW / (0.88 * 4.9m * 9.81m/s^2)

                   ≈ 943.44 m^3/s

d. To calculate the bearing thrust of the model, we can use the principle of force similarity:

  Bearing thrust model = (Model power / Full-size power) * Full-size bearing thrust

                      = (37.5kW / 27MW) * 7.0GN

                      ≈ 9.72kN

A landscaping company has charged $250 per yard for years, and long-term customers have always been pleased with the price. However, the company owner decides to raise prices, seemingly for no reason other than the desire to increase profits. Customers are unhappy and believe that the company should not raise prices just for its own benefit.

A price increase for no reason other than the desire to increase profits may be seen as unethical by many customers, especially if they are long-term and loyal customers who have been satisfied with the previous price.

This is a complex question that involves both economic and ethical perspectives. From an economic point of view, a company has the right to set its prices according to the market forces of supply and demand, as well as its own profit goals. However, from an ethical point of view, a company should also consider the impact of its pricing decisions on its customers, its reputation, and society at large.

According to price elasticity, there are several factors that can make a price increase more or less ethical, such as:

The nature of the product or service: Is it essential or discretionary? Does it affect people’s health, safety, or well-being?

The reason for the price increase: Is it justified by rising costs, improved quality, or increased value? Or is it motivated by greed, opportunism, or exploitation?

The communication of the price increase: Is it transparent, honest, and respectful? Or is it hidden, deceptive, or manipulative?

The timing of the price increase: Is it gradual, predictable, and fair? Or is it sudden, unexpected, and arbitrary?

The alternatives for the customers: Do they have other options to choose from? Or are they locked in or dependent on the product or service?

Based on these factors, a price increase for no reason other than the desire to increase profits may be seen as unethical by many customers, especially if they are long-term and loyal customers who have been satisfied with the previous price. Such a price increase may also harm the company’s reputation and trustworthiness, as well as invite negative feedback and backlash from the public.

Therefore, a company should carefully weigh the pros and cons of raising prices for no reason, and consider whether there are other ways to achieve its profit goals without alienating its customers or compromising its values.

Answer:

a) 19.44 ohm

b) 5.14 A

c) 51.9° lagging

Explanation:

A series RLC circuit containing a resistance of 12Ω, an inductive reactance of 47.13 Ω and a capacitive reactance of 31.83 Ω are connected in series across a 100V, 50Hz supply. Calculate the total circuit impedance, the circuits current, power factor

Given that:

R = 12 Ω, \(X_L=47.13\ ohm,\ X_C=31.83 \ ohm\), f = 50 Hz,  

A) Total circuit impedance (Z) is given by:

\(Z=\sqrt{R^2+(X_L-X_C)^2} =\sqrt{12^2+(47.13^2-31.83)^2} =\sqrt{378.09} =19.44\ ohm\)

B) the circuits current (I) is given by:

\(I=\frac{V}{Z}=\frac{100}{19.44}=5.14\ A\)

The voltage across the resistor (\(V_R\)) = IR= 5.14 × 12 = 61.68 V

The voltage across the inductor (\(V_L\)) = \(IX_L\) = 5.14 × 47.13 = 242.25 V

The voltage across the capacitor (\(V_c\)) = \(IX_C\) = 5.14 × 31.83 = 163.5 V

C) The power factor (Θ) is calculated as:

\(cos(\theta)=\frac{R}{Z}\\cos(\theta)=\frac{12}{19.44} =0.619\\\theta=cos^{-1}(0.6172)\\\theta=51.9^o\ laggin\)

The time taken to heat the water is  1.79 * 10^5 s.

We know that in this case, the principle of energy transformation holds true. The electrical energy is converted to the heat energy that causes the water to boil.

We then have;

IVt = mcdT

I = current

V = voltage

t = time taken

m = Mass of water

c = heat capacity of water

dT = temperature change

Thus;

230 * 13 * t = 1500 Kg * 4190 * (100 - 15)

The probability of getting a pair (but NOT three of a kind) in three-card poker would be 3744/22100 = .1694+.

Obviously any of the three cards NOT in the pair is equally likely to have been dealt to you last. So in the 1/3 of cases where the non-paired card was dealt last, then your criteria were met: first you got a pair, then you got something outside the pair. 1/3 of the above value is 1248/22100 = 0.05647+.

How did I get the 3744/22100 figure?

Explanation:

Wiring a doorbell button switch in the normally-open (NO) state is preferred because it is safer and more reliable than wiring it in the normally-closed (NC) state.

In a doorbell circuit, when the doorbell button is pressed, it completes the circuit and allows current to flow to the doorbell, causing it to ring. In the NC configuration, the button switch is always closed, and current flows through the circuit even when the button is not pressed. This can cause several problems, such as short circuits, overheating, and premature wear on the doorbell and other components in the circuit.

On the other hand, in the NO configuration, the button switch is open when it is not pressed, and no current flows through the circuit. When the button is pressed, it closes the circuit and allows current to flow, causing the doorbell to ring. This configuration is safer because it minimizes the risk of short circuits, overheating, and premature wear on the components in the circuit.

In addition to being safer, the NO configuration is also more reliable because it is less prone to false triggers. In the NC configuration, the button switch can be triggered by vibration, accidental contact, or other factors, causing the doorbell to ring unnecessarily. In the NO configuration, however, the button switch must be deliberately pressed to trigger the doorbell, making it less likely to ring accidentally.

Overall, wiring a doorbell button switch in the normally-open state is the preferred configuration for safety, reliability, and durability.

Wiring a doorbell button switch in the normally-open (NO) state is preferred because it is safer and more reliable than wiring it in the normally-closed (NC) state.
