If we observe a star’s spectrum and find that the peak power density occurs at the border between blue and ultraviolet light, what is the surface temperature of the star? (Remember to include units)Incorrect Submit QuestionQuestion 1Hi. I still don't get it. I'm not sure what sin and cos have to do with it. But either way, I'm still stuck in the same place. I don't know how you got from steps 3 and 4 to the next step. One is for the x-axis and the other for the y-axis. How did they end up merged together? If you apply the Pythagorean theorem, you get either:v = sqrt{(vcos) 2 + (vsin) 2} Then what? Or you get:v = sqrt{(m1v1/m1+m2)2 + (m2v2/m1+m2)2} Now what? That "adding" step just looks like the Pythagorean theorem, with v2 being the c in c2 = a2 + b2, but what is going on on the other side of the equation? I don't understand how in the denominator you went from:(m1 + m2)2 + (m1 + m2)2 to(m1 + m2)2It seems to me like (m1 + m2)2 + (m1 + m2)2 = 2(m1 + m2)2 Explain as if I didn't understand the algebra, because I think that's the issue here.
