Imagine that the three stars listed below all formed at exactly the same time, but in different locations of the universe. Cosmo Star is an O spectral class star with a MS lifetime of 3 million years. Its life will eventually end as a SN type II and become a black hole. Cosmo Star is located in a galaxy 10 billion light years (ly) from Earth. Ollie Star is a K spectral class star with a MS lifetime of 12 billion years. Its life will eventually end as a slowly cooling white dwarf. Ollie Star is located in the MW at a distance of 10,000 ly from Earth. Sullivan Star is an F spectral class star with a MS lifetime of 5 billion years. Its life will eventually end in a SN type I that will completely destroy Sullivan Star. Sullivan Star is located in a galaxy 6 billion ly from Earth. Which of these stars final end states will first be viewed on Earth

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
