What Are 2 Properties electromagnets have that permanent magnets do not?
Answers
Answer:The distinction between a permanent magnet and an electromagnet is essentially one in how the field is created, not the properties of the field afterwards. So electromagnets still have two poles, still attract ferromagnetic materials, and still have poles that repel other like poles and attract unlike poles.

How does supply and demand affect the development of technology?
Answers
Answer:
Shifts in the supply curve are usually the result of technological advancements that lower production input costs. Technological advancements that increase the efficiency of production will cause a supply curve to shift to the right. Consumers will demand more of the product at lower prices as the cost of production falls.

Opinion: Choose a side and defend it in four to five sentences. Given the choice between a vehicle that runs on gasoline or one that runs on electricity such as the Aptera 2e, which would you choose and why? Think about fuel consumption, design of the vehicles, and other factors that may influence your decision.
Answers
Answer:
my opinion would be electric
Explanation:
because when it comes down to the bare minimum the best choice for the world in the long run would be electric because it puts a big dent back for global warming and the burning of gasses so the more people who drive electric cars are the people who are trying to save the world a little at a time by preventing the burning of gasses. hope this helps :)

D. All variables should change.
ILL MARK BRAINLIEST
Answers
B. One variable should change, and the others should be kept the same.
Explaination:
In a well-designed experiment, researchers typically manipulate or change one specific variable, known as the independent variable, to observe its effect on another variable, known as the dependent variable. The independent variable is the factor that the researcher deliberately varies to test its influence on the dependent variable, which is the factor that the researcher measures or observes for changes. All other factors that could influence the results are kept constant or controlled, known as controlled variables, to isolate the impact of the independent variable on the dependent variable. This helps ensure that any observed changes in the dependent variable can be confidently attributed to the manipulation of the independent variable.
In an experiment, the factors that can change are called variables. The correct answer is B. One variable should change and the others should be kept the same.
When conducting an experiment, it is important to have a controlled environment. This means that all variables, except for the one being tested, should be kept constant. By changing only one variable, scientists can observe the effect that it has on the outcome of the experiment.
For example, let's say you want to investigate the effect of temperature on the rate of plant growth. In this experiment, you would keep all other factors, such as light, water, and soil type, constant. You would then vary the temperature and measure the growth of the plants. By changing only the temperature, you can determine its specific impact on the rate of plant growth.
By controlling the variables in an experiment, scientists can confidently attribute any changes observed in the outcome to the specific variable being tested. This allows for accurate and reliable results.
Therefore, in an experiment, one variable should change while the others are kept the same (option B).
B. One variable should change, and the others should be kept the same. In an experiment, it is important to only change one variable at a time while keeping all other variables constant. This allows researchers to observe the specific effects of that one variable on the results. Changing multiple variables at once can make it difficult to determine which variable is responsible for any observed changes.
In an experiment, variables are the factors that can potentially affect the outcome or results. The answer B states that in an experiment, one variable should change, while the others should be kept the same.
This is important because in order to understand the relationship between variables, it's necessary to isolate the effects of one specific variable at a time. By changing only one variable, called the independent variable, while keeping all other variables constant, we can observe how that one variable affects the outcome, known as the dependent variable.
For example, let's say you are conducting an experiment to investigate the effect of temperature on the rate of plant growth. You would keep factors such as soil type, amount of water, and light intensity constant. The only variable you would change is the temperature. By varying the temperature and observing the growth of the plants, you can determine the impact of temperature on plant growth.
This approach helps to establish a cause-and-effect relationship between the independent variable and the dependent variable. If multiple variables were changed simultaneously, it would be difficult to determine which variable was responsible for the observed changes in the outcome. Therefore, changing one variable at a time and keeping others constant allows for a clearer understanding of the relationship between variables in an experiment.
Describe the Optical Fiber Network( i need 2 paragraphs, but give me about 5 sentences or like 3)
Answers
Answer: Fiber Optic Network Fiber-optic networks have been used for decades to transmit large volumes of traffic across the country. The economics of fiber networks have only recently allowed for connecting the fiber directly to the home, creating a fiber-to-the-home (FTTH) network.
Explanation:
On the other hand, Fiber to the Curb (FTTC) is a partial fiber connection because the optical cables run to the curb near homes and businesses and copper cables carry the signals from the curb the rest of the way. Similarly, Fiber to the Building (FTTB) is when fiber cable goes to a point on a shared property and the other cabling provides the connection to offices or other spaces. When you’re on a FTTH network, you’ll experience significantly faster upload and download speeds, more bandwidth for multiple devices at home and a reliable connection. And that’s exactly what you’ll get with Verizon Fios, the 100% fiber-optic network.
With Fios Gigabit Connection speeds up to a blistering 940/880 Mbps Speeds up to 940 Mbps download and 880 Mbps upload available in select areas. , you’ll enjoy HD streaming, gaming, video conferencing and so much more on up 100 devices at a time –virtually lag-free. No wonder Fios has been rated #1 by industry leaders time and again. Shop for Verizon Fios and see if fiber internet is available in your area. A whole essay for you my boy ☝☝☝
Problem 4-2. A steam power plant operates on
an ideal reheat-regenerative Rankine cycle as
shown. Steam at a rate of 75 kg/s enters the high
pressure turbine at 10 MPa and 560°C and leaves
at 0.7 MPa. A fraction of the steam is extracted at
this pressure to heat the feedwater in a closed
feedwater heater. The rest of the steam is reheated
to 500°C and then it is expanded in the low-
pressure turbine to the condenser pressure of 10
kPa. It is assumed that the feedwater leaves the
closed feedwater heater (State 8) at the
condensation temperature of the extracted steam.
a: show the T-a diagram for the cycle, then calculate
B: the net power output
C: The thermal efficiency of the cycle
