- Q: A. carry electricity without resistanceB. may lead to better technology for car enginesC. suffer from inefficient power transmissionD. are not useful in electronics applicationsE. all of these answers
- Advantage of an electric machine using ceramic superconductors rather than the older metal superconductors:- Ceramic superconductors become superconducting at more easily obtainable liquid nitrogen temperatures. Disadvantages of an electric machine using ceramic superconductors rather than the older metal superconductors:- 1) Ceramic superconductors are fragile relative to metal conductors. 2) Ceramic superconductors cannot be bolted or welded together to form superconducting junctions. Ceramic superconductors must be cast in their final shape when created. This may increase production costs. 3) Ceramic superconductors can be more easily driven out of superconductivity by oscillating magnetic fields. This could be a problem during transient conditions, as during a sudden load or supply change. E. all of these answers
- Q: What‘s the difference?
- Well, from personal knowledge, chrome is metal. Metal gets hotter, but it fries your hair. It's also usually seen in the cheaper brand curling irons. Ceramic is believed to be gentler to the hair. They also heat up very quickly, but they are more expensive. I'd go for this brand and shell out a couple extra dollars. Either way, if you curl your hair frequently, go for a protection spray. Protect your hair. Hope this helped!

- tricky subject. browse on to the search engines. it can help!
- Q: Which brand of ceramic knives is of good quality?
- Global top ten brands of ceramic cutting tools:1, Zwilling - Germany was born in 1731, through foreign acquisitions and technological improvements, has become the world's highest standard of cutting tool symbol.2, Delisle - Germany was founded in 1818, is a high-tech engineering group in Germany, in the field of material technology has unique advantages.
- Q: Okay so im getting bracs and want to know about ceramic braces. Are they really all that visible or no? and can you tell from close up or not?
- HAHAHAHAHHAHA!! Thats me!!!! :-) I can change the oil in my car in about 15 minutes, but I have SUCH a problem with those snap on windshield wiper blades! I don't know why it's SO frustrating! I have to get help from my little brother it's embarrassing! :-) ** how did you know of my shame!
- Q: what are the industrial application of ceramics?
- Magnets, The space shuttle has them on the outside, circuit breakers,people have even made guns out of them. ceramics can withstand extremely high temperatures and do not conduct electricity like metals do we work with a lot of ceramics at my company and deal with many companies that are in the commercial ceramic industry. companies like true mugs bake ceramics at 1400F just to make the colors permanent, mostly they can go to 2400F
- Q: So, I‘m hoping to get my braces on before September and I was wondering if I were to get ceramic ones, would they have the same results as the metal ones? I really want the ceramic ones because they look more appealing and and a lot of my friends are getting their braces off and im about to begin so yeah. i would prefer the clear ones. if there are any people who have had experience w/ clear/ceramic please let me know, tips, how to get the best results would be much appreciated. thanks so much!
- I have ceramic ones on the top and metal ones on the bottom and they work the exact same. I've never had any ceramic brackets break off but a few metal brackets have broken off during tightening appointments, so they're just as strong. The only downside to ceramic is that the elastic ligatures (elastics) that they put on them stain easily if you eat things that are really tomato-y like tomato sauces or curry. You just have to watch what you eat and how you eat it and try to brush if you eat something that will stain them and you'll be okay. Even though they are a bit more work, I'm happy that I got the ceramic ones, especially since I'm almost 17 and braces wouldn't look that great. Good luck with your choice!
- Q: which is better for your hair?
- copper is a poor choise for many reasons it tarnishes quick it is soft and easily dented very expensive requires special skills to be able to work it forget copper use stainless steel if you need a metal surface.
