Answer: C) stars in these regions are hidden by interstellar dust grains.</h2>
Explanation:
Some areas of the Milky Way seem dark because those are areas of the galaxy that are hidden by huge columns of interstellar dust that we cannot see through the visible range of the electromagnetic spectrum (which is the range in which our eyes see).
However, to solve this problem, astronomers use telescopes that work in the range of infrared and radio waves, to observe a little more through this intersetelar dust.
1.Tainan=120dE
longitude difference=120-0=120
if 1degree= 4 minutes
120dg=(120×4)=480minutes
=8hrs
12:00pm + 8hrs
<h2> Ans=2000hrs or 8:00pm</h2>
<h2>Yukon =150dg W </h2><h3> 150×4=600minutes=10hrs</h3><h3> 12:00-10hrs=2:00am</h3><h2> =2:00AM</h2>
<h2> NOTE: if it's Degrees east you add by the time given and subtract by the time given when it's Degrees West</h2>
