From my senior high school boy's workbook:
Black holes are suspected when a visible star is beingt noticeably ulled by an invisible partner that is more than 3 times as massive aas the sun. A) If a red giant (a dying star) is gravitationally accelerated at 0.075m/s (square) toward an object that is 9.4 x 10 (to the tenth power) m away, how large a mass must the unseen body possess? B) How many times more massive is the object than the sun? Where the mass of the sun is: Mass of the sun = 1.99 x 10 (to the 30th power) kg)
