A star rotates in a circular orbit about the center of its galaxy. The radius of the orbit is 7.9 x 1020 m, and the angular speed of the star is 1.8 x 10-15 rad/s. How long (in years) does it take for the star to make one revolution around the center?
Homework Answers
angular speed = 
= 2
/T
where T is time period for one revolution
Hence , T = 2/ = 2 /
(1.8
10-15
) = 3.491 1015
s
time period in years = ( 3.491 1015
) / ( 3600 24 365
) = 1.11 108

A star near the visible edge of a galaxy travels in a uniform circular orbit. It is 42,700 ly (light-years) from the galactic center and has a speed of 275 km/s. Estimate the total mass of the galaxy based on the motion of the star. Gravitational constant is 6.674×10−11 m3/(kg·s2) and mass of the Sun Ms=1.99 × 1030 kg. The total visible mass (i.e., matter we can detect via electromagnetic radiation) of the galaxy is 1011 solar masses. What fraction...
