Homework Help: Physics

Posted by Alex on Friday, January 11, 2013 at 12:48pm.

Black Holes are suspected when a visible star is being noticeably pulled by an invisible partner that is more than 3 times as massive as the Sun. A red giant star is accelerated in a linear direction by gravity at 0.075 m/s2 towards an object that is 9.4 x1010 m away.

a) What is the mass of the invisible star? Answer using scientific notation (eg. 1e+10)
b) By what factor is the star more massive than our Sun? Answer in decimal.
