Plaskett's binary system consists of two stars that revolve In a circular orbit about a center of mass midway between them. This statement implies that the masses of the two stars are equal . Assume the orbital speed of each star is |v | = 240 km/s and the orbital period of each is 12.5 days. Find the mass M of each star. (For comparison, the mass of our Sun is 1.99 times 1030 kg Your answer cannot be understood or graded.

Complete Question

The complete question is shown on the first uploaded image

The mass is    

Explanation:

From the  question we are told that

       The mass of the stars are

        The orbital speed of each star is  

         The orbital period is

The centripetal force acting on these stars is mathematically represented as

     

The gravitational force acting on these stars is mathematically represented as

     

So  

=>        

=>      

=>      

=>    

The distance traveled by each sun in one cycle is mathematically represented as

     

     

     

Now this can also be represented as

     

Therefore

                 

=>  

=>    

So  

       

=>    

=>    

       

     

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4

No bc a lot of things r still theories n unproven
