In electromagnetics, what is the difference between lossless, lossy, non-magnetic, dielectric, perfect dielectric, insulating, conducting and perfect conducting mediums?
Sara, there is no such thing as ethnically Arabs. The Arabic language was first introduced within the 2nd century. So, earlier than the 2nd century, there used to be no such thing as an Arab. After the 2nd century, men and women who began speaking Arabic, which I think began in Iraq, had been known as Arabs, however they're ethnically Semitic. So the Canaanites could as well be the state-of-the-art Palestinians, as many Syrians and Lebanese (Phoenicians, and so forth.) had been tested to be former Canaanites they usually didn't adopt Arabic from Aramaic until later on. Either means, we definite have lived on that land for an extended period than exiled Jews, and we were normally known as the Philistines given that the day of Jesus Christ. Language and faith are inappropriate. If we're not the Canaanites, then 1400 years are longer than the 200 years that the americans lived in the usa or the 500 12 months conquest of Palestine with the aid of Israelites and Judaens who they stole faraway from the Canaanites.
Perfect and lossless mean the same thing. All magnetic and dielectric material have finite losses, but in many cases they are small enough to ignore.
