How did people engeenier the Chicago river to flow backwards?
Well, honey, back in the day, those folks in Chicago wanted to clean up their mess, so they dug a big ol' canal to reverse the flow of the river away from Lake Michigan. They basically said, "Sayonara, pollution!" and redirected the river like a boss. And that's how the Windy City ended up engineering the Chicago River to flow backwards.
Well, honey, using C as a target language for a compiler comes with some perks. C is a widely supported and portable language, making it easier to run your translated code on different platforms. Plus, C has been around the block a few times, so there are plenty of tools and libraries available to help you out. So, if you want your code to be as popular as avocado toast, C might just be the way to go.
Why are circuit breakers and contactors coated with silver?
Silver is used because it is the most conductive metal we have discovered. It also resists oxidizing, only doing so in the presence of sulfur, some halogens, and both nitric and sulfuric acids. The sulfur in many foods is what makes real silverware tarnish...a thin coating of sulfide is formed.

AnswerI think silver is supposed to be a good conductor of electricity. ANSWER:It prevents the contact points from corrosion and oxidation. Its not silver, its a mixture of tin and lead called solder. AnswerSilver is the best metallic electrical conductor...until it tarnishes (oxidizes)...at which point it becomes a rather poor conductor. Plated contacts are usually coated with Gold, which is almost as good a conductor as silver, but it's oxidized form still conducts about as well as pure gold. As for solder, it's usually a lead/tin alloy in electronics work, but can also be made with small amounts of silver as well. Lead in solder has been banned for piping where potable water is carried in the US. Answer: They're not.The issue isn't one of picking a metal or metal alloy that conducts well, but one that will resist damage or pitting due to electric arcing. Alloys with tungsten are often used. There are some other metals which can be alloyed to make arc resistant contacts, and they're all pretty exotic ones. Silver is the best metallic conductor at room temperatures under normal conditions, but switch contacts don't operate under "normal conditions" when they are opening and closing regularly.When a current carrying contact set (like in a switch or circuit breaker) comes open, an arc will begin across the forming gap. This arc will continue for a short while as the contacts get farther apart and eventually will be extinguished. The arc will cause a bit of damage to the contact surface for that little bit that it's happening. Soft metals like silver, gold, copper and aluminum will get pounded by the arc. It will shred them in such a short time that it isn't worth building a contact set with them, at least not on a contact set that is going to get a lot of work opening and closing.
How do you maintain a marking gauge?
1. You simply store in a carpenters belt.
2. keep the face of the measurement block and the slide clean and well lubricated. This will help it slide on the surface of the workpiece smoothly and makes adjustments easier, a little carnauba wax (or Butcher's Wax) is perfect for this, for both steel block and wooden block marking gauges. Be sure to wipe away the excess with a clean cotton rag. Also, keep the points well sharpened, this allows them to cut through the wood grain rather than tear at it. For mortise marking gauges, be careful you don't change the distances between the two points by over cutting the points when sharpening them, keep the points centered on the pins.
3. waxing the blocks and slides will help protect steel gauges from rusting.
Differetiate between solid earthing and ELCB?
ELCB is the connection to the direct earth path using protective device.while solid earthing is without protective device.A form of ELCB should be installed when direct earth path of low enough impendance can not be obtained.

If it's a regular hexagon, it can't be concave. If it's an irregular hexagon,
then it can be concave if it wants to, but it doesn't have to be.
Are you capable of chemistry physics and engineering if you are good at math?
That depends on many other factors. But I'd say that you're most likely
incapable of Chemistry, Physics, and Engineering if you're not good at Math.
What are the reasons some people are good at math but cannot write for their life?
Some people are good at one but not the other, some are good at both (but not other things), others are no good at either but are good at other things. People are different and their abilities are different.
Also, there may be differences in the way in which their brains work, in the teachers and other educational influences and so on.

Why are most engineering students smart in their field?
Because they're taught 1 subject which they major in, focusing more so on that topic than others.
Can you do chemistry if you're good at math and economics or is that a myth?
Being proficient in basic math (algebra) is extremely helpful if not required for chemistry on a high school level. Economics aren't really that relevant, except for the fact that it too relies extensively on mathematics.
I'm good at Math and I passed Chemistry.
Is calculus hard if you are excellent in basic algebra?
Not really. Of course, you'll have to learn some new concepts - just as when you learned algebra.

Which unit of measure is used the most in science and engineering around the world?
The unit of measurement used depends on what is being measured. For example, mass can be measured in grams (not pounds or ounces); length can be measured in inches, miles, meters; volume can be measured in gallons, liters, etc.
The metric system is most widely used, used in every country with the exception of America and Belize.
Although scientists and engineers have adopted the metric units as a standard, there are two different sets of metric systems that are employed based on the application. Those dealing with small units of length or mass tend to use the CGS system, while those dealing with large quantities tend to use the MKS system. Here, "CGS" stands for "centimeter-gram-second" and "MKS" stands for "meter-kilogram-second."
With industry heading more and more toward globalization, metric is becoming the standard throughout companies despite the failure of the United States to switch to the metric system because of the cost to change road signs, cars, and such.
The Metric System is much easier to convert into larger and smaller units.
Depends entirely on the size of the thing in question:-
If it's designed to go on the circuit board, nanometers
If it's around the size of your hand, millimeters.
If it's greater than a mile, I would suspect that it'd be meters.
So for around the world, millimeters for a general role. Nanometers used for components produced en mass. And Meters for construction.

Will calculus be hard for you as an individual if you got an A plus in algebra?
There is no way to know. Some aspects of calculus depend on a good understanding of algebra, others don't. It all depends on which aspects of algebra you were good at and also whether or not you retain that edge.
Are you capable of engineering if you're great with math and economics?
At least, you have a good chance. You'll need a lot of math in engineering. Also consider whether you like science in general, for example, physics.
Classes in writing are are typically required to earn a degree in science and engineering. Those classes determine whether or not a student has sufficient writing skills for science and engineering careers.
What is the proper orientation for the flat side of a square nut when installing?
The flat side should be facing downward, that is, towards the material you are tightening the nut to.
What types of degrees can you do if you are good at math but not at biology and writing code?
Math and physics would be safe bets, and depending on exactly what you struggle with in biology you might find chemistry a good choice. Engineering is an option, but you may need to learn to write code (but then again, the whole point of getting an education is learning how to do something you couldn't before, right?)
