You observe the peak brightnesses of two white dwarf supernovae. supernova a is only 1/4 as bright as supernova b. what can you say about their relative distances?

Supernova A must be further than Supernova B, because the more the distance, the less the brightness appears, and the closer you are, the brighter it seems. If Supernova A is 1/4 as bright as Supernova B, Supernova A must be twice as far away than Supernova B, meaning Supernova B is closer to wherever you are viewing.

A lot of Supernovas in one sentence, but, I hope this helps!

Can you give me little more information

Humid continental climate is found in the interior of continents between the 30 and 60 degrees latitude, but usually above the 40 degree line.   40 degrees north of the equator means less direct sunlight and therefore less warmth.   this climate is mainly found in the northern hemisphere since there are no major landmasses in the southern hemisphere.  if you live in northern indiana, you know all about humid continental because that is the climate type you have!
