Grade 9 Technology Project Term 3 Mini PAT Questions and Answers

Mini PAT 1: Situations where electronic circuits control electric circuits

An electronic circuit is different from an electric circuit because it only uses a very small current, and because it uses electronic control devices such as thermistors, LDRs, diodes and transistors.

There are many household appliances that use electronic circuits to control electric circuits with bigger currents.

The following two devices are used inside the electric switchboard (or distribution board) of every building that is connected with electricity in a safe way.

• Ordinary circuit breakers: Shuts off a circuit (for example the circuit supplying all the lights in a house) when the current becomes too big (if the current is too big for the thickness of wire used, the wire will overheat).
• Residual-current circuit breakers: Switches off the main power supply if it detects a leakage of power, such as when a person accidentally touches a “live” electrical wire or contact and the electricity is then conducted through his or her body. This device has to cut the current very quickly; otherwise the person can die due to electric shock. Therefore it switches off the power even when it detects only a small amount of leakage of electrical current.

The following household appliances use electronic circuits to control them:

• ovens: to control the temperature,
• radios and other music appliances: to control the volume of the speakers,
• some energy-saving lights: to switch off automatically when there is enough natural light, and
• kettles: to switch off when the water boils.

Questions and answers:

• Give two examples of situations or applications where electrical circuits are used.
• Give two examples of situations or applications where electronic circuits are used.
• Give three examples of situations or applications where electronic circuits and electric circuits are used together.

Give two examples of situations or applications where electrical circuits are used Answers:

Electrical circuits are used in a wide variety of applications, from simple household appliances to complex industrial equipment. Here are two examples of situations or applications where electrical circuits are commonly used:

• Lighting: Electrical circuits are used to power lighting in homes, offices, and public spaces. The circuit typically consists of a power source, such as a battery or mains electricity, connected to a switch and a series of light fixtures. When the switch is turned on, the circuit is completed, and electricity flows through the circuit to power the lights.
• Computing: Electrical circuits are a critical component of computers and other electronic devices. The circuitry in these devices includes components such as microprocessors, memory chips, and input/output devices, all of which are connected by circuits that allow for the flow of electricity. These circuits are responsible for carrying out the complex calculations and data processing that enable computers to perform their various functions.

Give two examples of situations or applications where electronic circuits are used Answers:

Electronic circuits are used in a wide range of applications, from small electronic devices to large industrial machines. Here are two examples of situations or applications where electronic circuits are commonly used:

• Consumer Electronics: Electronic circuits are used in a wide range of consumer electronic devices such as mobile phones, televisions, and computers. These circuits are responsible for processing and transmitting signals, powering the device, and controlling the device’s various functions. For example, a smartphone’s electronic circuits are responsible for processing data from the phone’s sensors, powering the phone’s display, and managing the phone’s battery life.
• Industrial Automation: Electronic circuits are also used in industrial automation applications, such as robotics and process control systems. These circuits can be used to control the movement of machines, monitor production processes, and ensure worker safety. For example, electronic circuits can be used to control the movement of robots in an automated factory or to monitor the temperature and pressure of a chemical process in a manufacturing plant.

Give three examples of situations or applications where electronic circuits and electric circuits are used together Answers:

Electronic and electric circuits are often used together in a variety of applications to provide a complete solution. Here are three examples of situations or applications where electronic circuits and electric circuits are used together:

• Home automation: In a home automation system, electronic and electric circuits work together to control various functions such as lighting, heating, and security. The electric circuit provides power to the system, while the electronic circuits process data from sensors and user inputs to control the system’s functions.
• Medical devices: In medical devices such as heart monitors, electronic and electric circuits work together to measure the electrical signals generated by the heart and provide information to medical professionals. The electric circuit provides power to the device, while the electronic circuits process and amplify the electrical signals generated by the heart.
• Automotive systems: In modern cars, electronic and electric circuits work together to control various systems such as the engine, transmission, and infotainment systems. The electric circuits provide power to the various systems, while the electronic circuits process data from sensors and user inputs to control the various functions of the car.

Mini PAT 2: Investigate: A circuit with an input sensor, control knob, transistor and output device.

A sensor is a control device that can have a variable effect . A switch can only be open (infinitely large resistance) or closed (zero resistance), so a switch is not a sensor. Devices such as thermistors and LDRs can have different resistances, depending on the temperature or amount of light. They can therefore be used as sensors. A device that can generate a voltage, such as a photovoltaic cell, can also be used as a sensor. A sensor “senses” something such as temperature, or light, just as your body’s senses do. A variable resistor is also a control device, but it is not a sensor, because it is a device for which the user can set the resistance.

The circuit for the fire alarm that you built in Chapter 5 can be used for different applications where a small input current from an input sensor has to switch on a circuit with a larger current for an output device. There is also a variable resistor so that the user can determine at what level of light or temperature (for example) the output device should be switched on or off.

• Name three input components that you know of.
• Name three output devices that you know of.
• Name a device that uses a control knob to set the level of something.

OpenAI has developed a 99.9% accuracy tool to detect ChatGPT content, but you are safe for now

Published on August 5, 2024

• OpenAI has developed a method to detect when someone uses ChatGPT to write essays or assignments.
• The method utilizes a watermarking system that is 99.9% effective at identifying AI-generated text.
• However, the tool has not yet been rolled out due to internal concerns and mixed reactions within the company.

When OpenAI launched ChatGPT towards the end of 2022, educators expressed concerns that students would use the platform to cheat on assignments and tests. To prevent this, numerous companies have rolled out AI detection tools, but they haven’t been the best at producing reliable results.

OpenAI has now revealed that it has developed a method to detect when someone uses ChatGPT to write (via The Washington Post ). The technology is said to be 99.9% effective and essentially uses a system capable of predicting what word or phrase (called “token”) would come next in a sentence. The AI-detection tool slightly alters the tokens, which then leaves a watermark. This watermark is undetectable to the human eye but can be spotted by the tool in question.

This technology is ready to be rolled out (and has been so for nearly a year), but the company has yet to do so because the project has been met with mixed reactions internally. On the one hand, launching this tool might mean pushing away a section of ChatGPT’s user base, but it also means that the artificial intelligence startup would be standing by its commitment to ensure transparency.

Additionally, the reporting outlet noted that an OpenAI spokeswoman revealed that the firm is concerned the tool could “disproportionately affect groups such as non-native English speakers.” Still, key employees within OpenAI who support the tool’s release believe that the technology can do a lot of good and, thus, shouldn’t be delayed any longer.

Generative AI tools like ChatGPT and Gemini can answer questions and write entire research papers based on a few, or sometimes even just one, well-directed prompts for free. You can imagine just how much these tools have changed things for both educators and students.

There is a caveat, though. Watermarks created by AI tools can often be erased by simple techniques like having the tool add emojis to the text and then deleting them manually or using Google Translate to change the text to another language and then translating it back to English.

Additionally, another concern about releasing an AI text detector is that if too few people use the platform, the tool wouldn’t really have any use. On the other hand, if too many people use it, it’s likely that OpenAI’s watermarking technique will not remain a secret for too long.

Only time will tell if the artificial intelligence startup is prepared to change things for itself and educators by releasing such a tool.

Tim Walz's military record: What to know about potential VP's National Guard service

Democratic presidential candidate Kamala Harris selected Minnesota Governor Tim Walz as her running mate on Tuesday, choosing a progressive yet plain-spoken VP candidate from America’s heartland to help her win over rural, white voters.

“I’m pleased to share that I’ve made my decision: Minnesota Governor Tim Walz will join our campaign as my running mate,” Harris said via text to supporters. “Tim is a battle-tested leader who has an incredible track record of getting things done for Minnesota families. I know that he will bring that same principled leadership to our campaign, and to the office of the vice president.”

We look at Walz, a 60-year-old U.S. Army National Guard veteran, and his military career over the years.

More: Tim Walz is Kamala Harris' VP pick: Minnesota governor named running mate: Live updates

How long was Walz in the military?

Walz served in the military for 24 years, enlisting in the Nebraska National Guard at 17 in 1981 and then transferring to the Minnesota National Guard in 1996. He retired in 2005 to begin his successful run for the U.S. House, representing Minnesota as command sergeant major, among the highest ranks for enlisted soldiers. His battalion went on to deploy to Iraq shortly after Walz's retirement.

Walz specialized in heavy artillery and had proficiency ribbons in sharpshooting and hand grenades.

But during the 21 years that Walz spent working with large artillery pieces, he suffered hearing loss and tinnitus in both ears, Minnesota Public Radio reported. He was allowed to continue his service after undergoing surgery, which partially resolved his hearing loss.

Where did Walz serve, and what did he do in the National Guard?

During his service, Walz responded to natural disasters, including floods and tornadoes in Minnesota and Nebraska, and was deployed overseas for months at a time, according to MPR.

In 2003, he was sent to Italy, where he served with the European Security Force to support the war in Afghanistan. He was also stationed in Norway for joint training with other NATO militaries.

Walz told MPR that he reenlisted in the National Guard after the September 11 attacks but never saw active combat in his years in the military.

Stars and Stripes reported in 2020 that Walz credited his Army experience with helping him steer Minnesota through the COVID-19 pandemic as governor.

As governor of Minnesota, Walz is commander in chief of the 13,000-soldier Minnesota National Guard. “I’m certainly proud of my military service, but it’s one piece of me,” he told Minnesota Public Radio in 2018. “It doesn’t define me.”

Reuters and USA TODAY reporter Tom Vanden Brook contributed to this story.

19 Facts About Tim Walz, Harris’s Pick for Vice President

Mr. Walz, the governor of Minnesota, worked as a high school social studies teacher and football coach, served in the Army National Guard and chooses Diet Mountain Dew over alcohol.

• Share full article

By Simon J. Levien and Maggie Astor

• Published Aug. 6, 2024 Updated Aug. 9, 2024, 8:04 a.m. ET

Until recently, Gov. Tim Walz of Minnesota was a virtual unknown outside of the Midwest, even among Democrats. But his stock rose fast in the days after President Biden withdrew from the race, clearing a path for Ms. Harris to replace him and pick Mr. Walz as her No. 2.

Here’s a closer look at the Democrats’ new choice for vice president.

1. He is a (very recent) social media darling . Mr. Walz has enjoyed a groundswell of support online from users commenting on his Midwestern “dad vibes” and appealing ordinariness.

2. He started the whole “weird” thing. It was Mr. Walz who labeled former President Donald J. Trump and his running mate, Senator JD Vance of Ohio, “weird” on cable television just a couple of weeks ago. The description soon became a Democratic talking point.

3. He named a highway after Prince and signed the bill in purple ink. “I think we can lay to rest that this is the coolest bill signing we’ll ever do,” he said as he put his name on legislation declaring a stretch of Highway 5 the “Prince Rogers Nelson Memorial Highway” after the musician who had lived in Minnesota.

4. He reminds you of your high school history teacher for a reason. Mr. Walz taught high school social studies and geography — first in Alliance, Neb., and then in Mankato, Minn. — before entering politics.

5. He taught in China in 1989 and speaks some Mandarin. He went to China for a year after graduating from college and taught English there through a program affiliated with Harvard University.
