We observe a glowing cloud of gas in space with a spectroscope. We note that many of the familiar lines of hydrogen that we know

on Earth seem to be in a different place. They are shifted toward the blue or violet end of the spectrum compared to their positions in the spectrum of glowing hydrogen gas on Earth. From this we can conclude that:A. the cloud is much hotter than hydrogen on EarthB. the cloud is moving away from usC . the cloud is moving toward usD. the cloud is much cooler than hydrogen on Earth

Luxembourgish, a language unique to Luxembourg, is most closely related to which other language?
12345 [234]
<span>German and French are the most spoken
and aprox... 390,000 people worldwide speak Luxembourgish.

Luxembourgish is also spoken in small parts of the surrounding countries of Belgium (in the Province of Luxembourg near Arlon), France (in small parts of the Lorraine) and Germany (around Bitburg and Trier). In Germany and Lorraine it is simply considered the local German dialect. Since the Second World War, however, the language has not been taught in these countries, with the result that use of Luxembourgish is largely restricted to the older generations.

Furthermore, the language is spoken by a few descendants of Luxembourg immigrants in the United States, and a closely related variety is spoken by ethnic Germans long settled in Transylvania, Romania (Siebenbürgen). </span>

F f(x) = 3x^2 + 1 and g(x) = 1 – x, what is the value of (g – f)(2)?
Finger [1]

Answer: f(x) = 3x^2 + 1

g(x) = 1 - x

(f - g)(x) = 3x^2 + 1 - (1 - x) = 3x^2 + 1 - 1 + x = 3x^2 + x

(f - g)(2) = 3(2)^2 + 2 = 3(4) + 2 = 12 + 2 = 14.

In which country is it said that finding a spider web on christmas morning brings good luck
andreyandreev [35.5K]

Answer:

Ukraine and Germany

Explanation:

Spiders may seem like a more specific Halloween ornament, but eight-legged creatures actually play an important role in other parties. We have discovered the tradition of "Christmas spiders."

It is based on a European folk tale that has been attributed to several countries, often Ukraine and Germany. In a version of the Christmas spider story, a widowed mother and her children were too poor to decorate their Christmas tree, and friendly spiders wove elaborate nets on a fir tree. When the family woke up on Christmas morning, they opened the curtains and sunlight illuminated the cobwebs, turning them into silver and gold (sometimes it is said to be the origin of the garlands). The family had good fortune thereafter. Other versions affirm that it was Santa Claus or Jesus himself who transformed the networks so that they did not bother the mother.

It is likely that the legend is related to the idea that spiders give good luck. Whatever the real reason, according to various sources, Ukrainians decorate their Christmas trees with spider-shaped ornaments (often made of precious stones) to this day
