Questions

Cоmpаre the luminоsities оf а `а` magnitude and `b` magnitude stars. You will then use your answer to interpret the next question. Please read and comply with my (not optional) input instructions. Hint: See equation sheet in the exam instructions for guidance. Input Instructions: In typing your answer, only type a number rounded to one decimal place (i.e. 350.475 would be written as 350.5). Do not include any units, E, words, or scientific notation. Seriously, just a number. Use standard comma placement if necessary. If your answer does not match my answer exactly, you will not receive credit. If any technical issue prevents you from typing into the input box, just write out your answer following the same input instructions in the bonus section at the end of the exam.
