The Sun, with Earth in tow, orbits about the center of the Milky Way galaxy at a speed of 137 miles per second, completing one revolution every 240 million years. (a) Find the angular speed of the Sun relative to the center of the Milky Way. (b) Find the distance from the Sun to the center of the Milky Way.
Solution 103 GP:
Step 1 of 2:-
a)
Here we have to find the angular speed of sun relative to the center of milky way galaxy.
The speed of sun around milky way is given as,
.
The time period for 1 revolution is,
.
We know that,
So, the angular speed of sun, relative to the center of milky way galaxy is .
