Different stages of the cycle gives off different wavelengths of light because more types elements are being made as you go farther down the cycle. So looking at the wavelengths that the light gives off can determine what stage a star is currently in
Answer:
B. +m
Explanation:
The magnification of an image is defined as the ratio between the size of the image and of the object:

where we have
y' = size of the image
y = size of the object
There are two possible situations:
- When m is positive, y' has same sign as y: this means that the image image is upright
- When m is negative, y' has opposite sign to y: this means that the image is upside down
Therefore, the correct option representing an upright image is
B. +m
