Answer:
[tex]V_{out} = 460[/tex]
Explanation:
From your question, you already posted the answer
However, I'll give the steps to get the answer
Given
[tex]Primary\ Voltage = 230V[/tex]
[tex]Primary\ Coil = 80[/tex]
[tex]Secondary\ Coil = 160[/tex]
Required
Secondary Voltage
The relationship between the primary voltage, secondary voltage, turns of primary coil and secondary coil is as follows;
[tex]\frac{V_{out}}{V_{in}} = \frac{N_{s}}{N_{p}}[/tex]
Where
[tex]V_{in} = Primary\ Voltage = 230V[/tex]
[tex]V_{out} = Secondary\ Voltage = ??[/tex]
[tex]N_{p} = Primary\ Coil = 80[/tex]
[tex]N_{s} = Secondary\ Coil = 160[/tex]
Substitute these values in the formula above;
[tex]\frac{V_{out}}{V_{in}} = \frac{N_{s}}{N_{p}}[/tex]
becomes
[tex]\frac{V_{out}}{230} = \frac{160}{80}[/tex]
[tex]\frac{V_{out}}{230} = 2[/tex]
Multiply both sides by 230
[tex]230 * \frac{V_{out}}{230} = 2 * 230[/tex]
[tex]V_{out} = 2 * 230[/tex]
[tex]V_{out} = 460[/tex]
Hence, the secondary voltage is 460 Volts
Answer:
460 volts

What are limitations of AI
Explanation:
Limitations of artificial intelligence. One of the main barriers to implementing AI is the availability of data. Data is often siloed or inconsistent and of poor quality, all of which presents challenges for businesses looking to create value from AI at scale.
Answer:
Risks and limitations of artificial intelligence in business
Businesses are increasingly looking for ways to put artificial intelligence (AI) technologies to work to improve their productivity, profitability and business results.
However, while there are many business benefits of artificial intelligence, there are also certain barriers and disadvantages to keep in mind.
Limitations of artificial intelligence
One of the main barriers to implementing AI is the availability of data. Data is often siloed or inconsistent and of poor quality, all of which presents challenges for businesses looking to create value from AI at scale. To overcome this, you should have a clear strategy from the outset for sourcing the data that your AI will require.
Another key roadblock to AI adoption is the skills shortage and the availability of technical staff with the experience and training necessary to effectively deploy and operate AI solutions. Research suggests experienced data scientists are in short supply as are other specialised data professionals skilled in machine learning, training good models, etc.
Cost is another key consideration with procuring AI technologies. Businesses that lack in-house skills or are unfamiliar with AI often have to outsource, which is where challenges of cost and maintenance come in. Due to their complex nature, smart technologies can be expensive and you can incur further costs for repair and ongoing maintenance. The computational cost for training data models etc can also be an additional expense.
Software programs need regular upgrading to adapt to the changing business environment and, in case of breakdown, present a risk of losing code or important data. Restoring this is often time-consuming and costly. However, this risk is no greater with AI than with other software development. Provided that the system is designed well and that those procuring AI understand their requirements and options, these risks can be mitigated.
See also Industry 4.0 challenges and risks.
Other AI limitations relate to:
implementation times, which may be lengthy depending on what you are trying to implement
integration challenges and lack of understanding of the state-of-the-art systems
usability and interoperability with other systems and platforms
If you're deciding whether to take on AI-driven technology, you should also consider:
customer privacy
potential lack of transparency
technological complexity
If you're considering writing a tender document to procure AI, you can seek help from the Northern Ireland Artificial Intelligence Collaborative Network(link is external).
AI and ethical concerns
With the rapid development of AI, a number of ethical issues have cropped up. These include:
the potential of automation technology to give rise to job losses
the need to redeploy or retrain employees to keep them in jobs
fair distribution of wealth created by machines
the effect of machine interaction on human behaviour and attention
the need to address algorithmic bias originating from human bias in the data
the security of AI systems (eg autonomous weapons) that can potentially cause damage
the need to mitigate against unintended consequences, as smart machines are thought to learn and develop independently
While you can't ignore these risks, it is worth keeping in mind that advances in AI can - for the most part - create better business and better lives for everyone. If implemented responsibly, artificial intelligence has immense and beneficial potential.
Another problem related to indefinite postponement is called ________. This occurs when a waiting thread (letâ s call this thread1) cannot proceed because itâ s waiting (either directly or indirectly) for another thread (letâ s call this thread2) to proceed, while simultaneously thread2 cannot proceed because itâ s waiting (either directly or indirectly) for thread1 to proceed. The two threads are waiting for each other, so the actions that would enable each thread to continue execution can never occur.
Answer:
"Deadlock" is the right solution.
Explanation:
A deadlock seems to be a circumstance where certain (two) computer algorithms that share a similar resource essentially prohibit each other during manipulating the asset, leading to both programs withdrawing to operate.This occurs when multiple transfers or transactions block everyone by maintaining locks onto assets that every other activity also needs.So that the above is the correct answer.
"Consider the following code snippet: int number = 0; Scanner in = new Scanner(System.in); System.out.print(""Enter a number: ""); number = in.nextInt(); if (number > 30) { . . . } else if (number > 20) { . . .. } else if (number > 10) { . . . } else { . . . } Assuming that the user input is 40, which block of statements is executed?
a. if (number > 30) { . . .}
b. else if (number > 20) { . . .}
c. else if (number > 10) { . . .}
d. else { . . .}
Answer:
if (number > 30) {. . .}
Explanation:
This code block uses a simple if-elseif-else control structure to do a comparison on a value. In this type of control structure, each operation of control is check until the correct condition is met, and once the code executes, it exits the control structure, never touching the remainder of the structure.
In this example, we are fortunate that the value triggers the first part of the control structure with if (number > 30) and will execute that section of code. Once the code finishes, it will exit the structure, never making it to the other 3 control conditions.

write down a description of how a magnetic had drive works
Answer:
This is how a magnetic hard drive works
Explanation:
The hard drive contains a spinning platter with a thin magnetic coating. A "head" moves over the platter, writing 0's and 1's as tiny areas of magnetic North or South on the platter. To read the data back, the head goes to the same spot, notices the North and South spots flying by, and so deduces the stored 0's and 1's.

They provide only information from reliable sources. They provide immediate access to information on the web. They take longer than using a card catalog but provide only expert sources.
Answer:
because it is easy to access not hard not all things from the internet are reliable they don't always have expert sources
Explanation:
Search engines like Google, Bing, and Yahoo! have revolutionized research.
The best answer choice for this is that "they provide immediate access to information on the web".
The other choices would be wrong because...
Answer choice A, would be incorrect due to the fact that using the search engines makes it easier to access information than a library as you do not need to walk around the library looking for a book to provide you the answers to your question.
Answer choice B, would be false since the web doesn't always provide only reliable information from creditable sources. In fact, quite a few of the sources on the web that come up, are not helpful or do not assist the user in answering their questions.
Answer choice D, would be wrong since using the search engine to find information is quicker than using a card catalog, and also it does not only provide expert sources since any source of information could pop up when the user searches for it.

3. What does a production sound mixer do? Which responsibility of a production sound mixer do you think sounds most difficult and why? A production sound mixer has many duties, he has to announce each take that is being films, he also is responsible for recording voice-overs/wild lines. In my opinion the most difficult is recording the wild lines because the dialogues and all the film lines are in your hands, it's a lot of responsibility and you need to be very organized to keep track of all the lines you need to record and make sure that everything sounds right.
Answer:
The production sound mixer has various jobs around the studio, such as slating, wild lines, voice-overs, and background sound effects. Their hardest is likely slating, which requires a bit more precision than their other jobs.
Explanation:
"What does a production sound mixer do? Which responsibility of a production sound mixer do you think sounds most difficult and why?"
Straight from the lesson related to this question:
In getting sound right for a film, equipment is only part of the story. People are also needed to best use that equipment... On smaller-budget films, the filmmaker may select a production sound mixer who has his or her own equipment as this choice can save the filmmaker a considerable amount of money in sound equipment rental, and the mixer is likely to be skilled in using his or her own equipment.
In short, the production sound mixer is a person hired to mix sounds together in a film production. They have several responsibilities, such as those included in the passage below:
The responsibilities of the production sound mixer position can vary, again depending on the film's budget, needs, and size of crew. However, the production sound mixer does perform certain functions for almost every film. For example, s/he announces each take that is filmed and is responsible for slating. Slating is the use of the film slate, also called a clapboard, which shows specific information about each take, such as the date, director, production, scene number, and take number.
The production sound mixer can also be responsible for recording voice-overs, which are actors' lines that are not spoken by the actors within the scene... The sound mixer also records what are called "wild lines," which are lines that the actors repeat because the originals were not spoken or recorded clearly enough for the film's needs. He or she may not necessarily be responsible for creating the sound effects, but he or she may be responsible for recording the sound effects that someone else creates.
The production sound mixer has various jobs around the studio, such as slating, wild lines, voice-overs, and background sound effects. Their hardest is likely slating, which requires a bit more precision than their other jobs.
