What Are 2 Properties electromagnets have that permanent magnets do not?
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.

15. What is the preferred repair for 4130 steel tube that may
be visible or adjacent to the fabric covering?
Answer:
The correct answer to the following question will be "Austenitic stainless steel fillers".
Explanation:
Some manufacturers prefer welding 413 type tubing or pipes to use austenitic filters, this seems to be appropriate because they use 310 as well as 312 stainless additives. Certain fillers made from stainless steel could perhaps provoke crack propagation. A stainless filler surface is generally extra costly.So that the above would be the right answer.

Describe 3 factors an engineer should take into consideration when choosing material for building the pipes in a pipeline
Gr. 8
Think it has something to do with Viscosity, Density, and Pressure but not sure what
Answer:
Durability: The material used for building pipes in a pipeline should be able to withstand the conditions it will be exposed to, such as pressure, temperature changes, and corrosion.Flow properties: The viscosity and density of the liquid or gas that will be flowing through the pipeline should be taken into consideration when choosing the material for the pipes. Materials with lower viscosity and density will be more suitable for transporting fluids with high flow rates.Cost: The cost of the material used for building pipes in a pipeline is an important consideration. Engineers need to choose a material that is both durable and cost-effective, while still being able to meet the flow and pressure requirements.Answer:
design, material, cost

(Please help me I'm struggling) The United States spends over $20 billion a year on space exploration through NASA. Do you think that this has been worth the cost? In three to five sentences, provide two specific examples of things we have learned from space exploration, and explain how these examples influence your opinion.
Answer:
Explanation: Sunday, July 20, marked 45 years since the United States put the first two astronauts safely on the moon. The cost for the Mercury, Gemini and Apollo programs was more than $25 billion at the time more like $110 billion in today’s world. The ensuing U.S. space efforts have cost an additional $196 billion for the shuttle and $50 billion for the space station. NASA’s total inflation-adjusted costs have been more than $900 billion since its creation in 1958 through 2014 (more than $16 billion per year). Looking back, have we gotten our money’s worth from the investment? I say yes.
Yes, the investment in space exploration through NASA has been worth the cost.
What are examples to this assertion?Two significant examples demonstrate its value. Firstly, space exploration has led to a deeper understanding of Earth's environment, including climate change patterns and natural disaster prediction. This knowledge helps address global challenges.
Secondly, exploration of Mars has provided insights into the potential for extraterrestrial life and the evolution of habitable planets, expanding our understanding of the universe and humanity's place in it.
These advancements in knowledge and their practical implications underline the long-term benefits and enrichment of scientific knowledge gained from space exploration.

A student places a cube of solid butter at the tip of a metal spoon. The base of the spoon is placed in a pot of hot water so that only the spoon’s base is touching the water.
After a few minutes, the butter starts to melt from the tip of the spoon. Which statement explains the process that causes the butter to melt?
Answer:
The thermal energy from the pot of water rises into the air and the butter absorbs the heat and the butter slowly change’s from a solid to a liquid.
Explanation: It will melt because when you put the spoon under hot water It will become heated. So when you put butter on it It is going to melt because the things inside of the butter will make it melt
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.
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 :)

All of the factors that can change in an experiment are called variables. Which of the following is true about the variables in an experiment?
A. All variables should be kept the same.
B. One variable should change and the others should be kept the same.
C. One variable should be kept the same and at least two variables should change.
D. All variables should change.
ILL MARK BRAINLIEST
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.
