Hiiiiiiii honeyyyyy hehehehe
Im not quite sure butttttt im thinkin it would be either B or C, hope i helped u :)
Your answer should be D geography
Answer: D. It increases from top to bottom on an H-R diagrams
<span>Luminosity is defined in the wordbook as brightness of a celestial object. In astronomy, it stands for the total amount of energy emitted per unit time by a star, so C. is correct. It is measured in joules per second or watts so A is correct also. It is B, valued at 1 for our sun. </span>
In an H-R diagram, the energy of a star is plotted on the vertical axis. The lower or more negative the measure, the brighter the star, D is therefore not true.
