The solar system is 25,000 light years from the center of our milky way galaxy. one light year is the distance light travels in one year at a speed of 3.0×108m/s. astronomers have determined that the solar system is orbiting the center of the galaxy at a speed of 230 km/s.
assuming the orbit is circular, what is the period of the solar system's orbit? give your answer in years

years

Explanation:

Period is:

The speed of the galaxy is 230 km/s. Its angular speed is given by:

  Where R=25000 light years

Now, let N be the amount of seconds in 1 year.

This value will be in meters.

Replacing this value:

Now, the period will be:

 This value is in seconds. Since we are asked to give the answer in years, we have to divide by N (amount of seconds in a year:

years

where are the vectors ?

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
