A red supergiant is observed in a globular cluster in another galaxy (located 150,000 light years away). It is predicted, based on its mass and age of the star that it will supernova in about 10,000 years. Is this star still there?
A) No, it died in a supernova 10,000 years ago. B) No, it died in a supernova 140,000 years ago. C) No, it died in a supernova 150,000 years ago. D) Yes, it will die in a supernova in 10,000 years. E) Yes, it will die in a supernova 160,000 years from now.
Process of Science: Devise an experiment that would produce evidence (not necessarily proof) that Earth is round. You may use any technology you like, but you may not leave Earth (i.e., no satellite photos and no space travel)

Two masses, MA and MB, with MB = 2MA, are released at the same time and allowed to fall straight down. Neglect air resistance. When we compare their kinetic energies after they have fallen for equal times, we find that
a. KB = KA. b. KB = 2KA. c. KB = 4KA. d. KA = 2KB. e. KA = 4KB.
