Certain neutron stars (extremely dense stars) are believed to be rotating at about 0.83 rev/s. If such a star has a radius of 40 km, what must be its minimum mass so that material on its surface remains in place during the rapid rotation? Number Enter your answer in accordance to the question statement Units Choose the answer from the menu in accordance to the question statement

The mass of the star would be      

Explanation:

From the question we are told that

     The angular speed is  

      The radius of the star is      

Generally the minimum mass of the start is mathematically evaluated as

Where is the gravitational constant with a values of  

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

b.a device that inputs heat into a cool object
