ANSWER:
Solution
Step 1 of 3
A) To measure masses of the stars in an eclipsing binary system. By using Kepler’s 3rd law which is applied to the motion of binary stars and then we get the combination of two stars are
The distance between stars and the time taken by the unit of years for the orbital period.
