Complete the following parts a-c based on the negative, and the magnitude scale below the negative Page 5 ol 15 4042 wends E + 100% 128 AM Type here to search Auto E-lab 33..

a f e d c h b g
c) m starA = 0, m starB =6, m starD =3, m starF =1, m starG = 7
3a) m starA = 0, m starC = 4
m starC-A = 4-0 =4
3b) Star F appears the brighter because the apparent magnitude of star C is 4 that is greater than that of apparent magnitude of star F that is 1.
3c) Magnitude difference between C & B= 6-4 = 2
For corresponding value of 2 the brightness value will be 6.3 as per the table given in que.
3d) For 2.5 brightness ratio the magnitude difference between star E & other star must be equal to 1.
The magnitude of star E is 2 so the star the will be 2.5 times dimmer than E will have magnitude 1 more than E. Clearly, star D have have a magnitude of 3.
3 e) For 40 brightness ratio the magnitude difference between star C & other star must be equal to 4.
The magnitude of star C is 4 so the star that wil 40 times brighter than C will have magnitude 4 less than C. Clearly, star A have have a magnitude of 0.
