Answer:
Nuclear fission is almost 8,000 times more efficient than traditional fossil fuels at producing energy. That's a lot of energy packed into a small space. Nuclear energy is more efficient, which means it uses less fuel to power the plant and produces less waste.
advantages:
-produces no polluting gases
-does not contribute to global warming
-very low fuel costs
-Low fuel quantity reduces mining and transportation effects on environment
-High technology research required benefits other industries
-Power station has very long lifetime
Disadvantages:
-Waste is radioactive and safe disposal is very difficult and expensive
-Local thermal pollution from wastewater affects marine life
-Large-scale accidents can be catastrophic
-Public perception of nuclear power is negative
-Costs of building and safely decommissioning are very high
-Cannot react quickly to changes in electricity demand
3. Low-voltage conductors rarely cause

Read an excerpt from Benito Mussolini’s "The Doctrine of Fascism.” In the Fascist State, the individual is not suppressed, but rather multiplied, just as in a regiment a soldier is not weakened, but multiplied by the number of his comrades. The Fascist State organizes the nation, but it leaves sufficient scope for individuals; it has limited useless or harmful liberties and has preserved those that are essential. It cannot be the individual who decides in this matter, but only the State. What is the purpose of this excerpt? to explain the foreign policy of a fascist state to explain the role of citizens in a fascist state to describe the life of a soldier in a fascist state to describe the life of an official in a fascist state
Answer:
B. to explain the role of citizens in a fascist state
Explanation:
Benito Mussolini was a Journalist, the leader of the National Fascist Party in Italy as well as the Prime Minister of Italy between 31 October 1922 to 25 July 1943. Benito Mussolini promoted Fascism, a political system that promoted a Corporatist economy where the society is structured according to corporate groups like agriculture, military, science, etc.
In the excerpt above Mussolini was emphasizing on the role of individuals or citizens in a Fascist state. He explained that a Fascist society does not suppress citizens, but rather organizes the nation and has few harmful liberties. In organizing the nation, individuals benefit as their essential liberties are preserved.

The distance between the Sun and the Earth is 150000000km (approximately) and the Sun subtends an angle of 32' with eye of man of the Earth, find the diameter of the Sun.
Answer:
the diameter of the Sun is approximately 1.392 million kilometers.
Explanation:
To find the diameter of the Sun, we can use the formula:
diameter = 2 x distance x tan(angle/2)
where distance is the distance between the Sun and the Earth, angle is the subtended angle of the Sun, and tan is the tangent function.
Substituting the values given, we get:
diameter = 2 x 150000000 km x tan(32'/2)
diameter ≈ 1.392 x 10^6 km
Therefore, the diameter of the Sun is approximately 1.392 million kilometers.

Explanation:
A water turbine is to be designed to produce 27MW when running at 93.7 rev/min
under a head of 16.5m. A model turbine with an output of 37.5kW is tested under
dynamically similar conditions with a head of 4.9m . Calculate the:
a. model speed; b. scale ratio; c. assuming a model efficiency of 88%, estimate the volume
flow rate through the model; and d. if it is estimated that the force on the thrust bearing of
the full-size machine is 7.0GN , determine the bearing thrust of the model.
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

Contractor Control Circuits
Answer: A contactor is an electrically-controlled switch used for switching an electrical power circuit. A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch
Is a contactor bad?The most common situation in contactor failures is contact sticking and coil burning. The reason for contact sticking; If more current is passed through the main power contacts than it can carry, the contacts will overheat after a while and the contacts may stick as a result of this warming.

Pk runs a restaurant two workers who prepare food for 50 heads every day.he received an order to prepare food for 200 heads. with the help of graph, explain how it will affect the demand for labour?
Note that where the above ocndition exists, as the demand for labor increases due to the increased order, the demand curve shifts to the right, indicating that Pk will be willing to hire more workers at a higher wage rate to meet the new demand for food preparation.
What is the explanation for the above response?Assuming that the two workers can prepare food for 50 heads per day, it means they can prepare food for 250 heads in five days (50 heads/day x 5 days = 250 heads).
However, with the new order of preparing food for 200 heads, Pk will need to increase the demand for labor to meet the new demand. One way to show this on a graph is by using a labor demand curve, which illustrates the relationship between the quantity of labor demanded and the wage rate.
As the demand for labor increases due to the increased order, the demand curve shifts to the right, indicating that Pk will be willing to hire more workers at a higher wage rate to meet the new demand for food preparation.

Stripping tools designed for solid wire cannot be used on stranded wire. Why?
Answer:
One reason why stripping tool designed for use with solid wire cannot be used on stranded wire is that the diameter of a stranded wire is larger than the diameter of a solid wire of the same gauge.
Therefore, a tool for stripping a 8-gauge solid wire cannot be used for stripping a 8-gauge stranded wire as the diameter of an American Wire Gauge, AWG 8-guage solid wire (0.129 inches in diameter) is smaller than the diameter of an AWG 8-gauge stranded wire (0.152 inches in diameter)

We can see here that the law of resistivity, also known as Ohm's law, states that the electrical resistance of a conductor is directly proportional to its resistivity and length, and inversely proportional to its cross-sectional area.
How is law of resistivity represented?The Law of resistivity can be mathematically represented as:
R = ρ × (L / A)
Where:
R is the electrical resistance of the conductor,
ρ (rho) is the resistivity of the material,
L is the length of the conductor, and
A is the cross-sectional area of the conductor.
The resistivity (ρ) is a characteristic property of a material that quantifies its ability to resist the flow of electric current. It depends on the nature of the material, its temperature, and sometimes its purity. Resistivity is measured in ohm-meters (Ω·m).
