I have 3 questions on my homework where I can't find any information in the notes or book. Can anyone help?

1. a star's brightness decreases with the square of the distance from the star. the power/ unit area reaching the Earth from the Sun equals 1370 watts/m2. What is the solar power / unit area reaching Saturn, which is at a distance of 9.5 AU

2. Some stellar remnants (essentially dead stars) can have surface temperatures as high as 30,000 K and yet have a luminocity of only 0.05 x the solar luminocity. What can explain this?
-they are very very small
-they are very very distant from earth
-they radiate in an undectable part of the electromagnetic spectrum

3. Consider a star with a surface temp of 21,500 K. In what part of the electromagnetic spectrum would the dominant spectral wavelength be observed?
-microwave
-infrared
-visible
-ultraviolet

Okay I asked this question yesterday but I forgot to add the link to the moon chart thing. I reposted it but no one has responded to it. Anyways how accurate would you say that this moon chart is? And another thing how would I use the chart in day light savings time. I'm not sure weather GMT has daylight savings. Should I use the chart to a clock that been set back an hour or do I use it to a clock that has been set foward? here is the link. Thanks in advance

ive just got my head around what 1' and 1" actually mean, after much confusion because of their name. but now i understand what ' and '' actually denote, as in, they are simply the angles subtended in their respective periods of time, i still dont understand where the name arc minutes comes from.

so could somebody please explain how a unit goes from being a name like degrees, then breaks down into arc minutes, arc seconds. why pick these names instead (just examples for illustrating my point here) of millidegrees, microdegrees...???

I read an artical saying that black holes may not exist. I am kind of confused. How do they form? How do they disappear? Will they ever hit Earth or the sun?
