Stephan hawkins worked extensively with theoretical gravitational physics. he is well known for his work with black holes. he passed on march 14th, 2018. it has been observed that a certain star (s2) in the sagittarius a* (meaning in the direction of the constellation sagittarius) is orbiting a supermassive black hole. if the period of s2 is 16year and the distance between the two is 1.79e13m. what is the mass of this black hole? (be careful with your units)

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
