Five identicаl quintuplets leаve eаrth when they reach the age оf 21, in the year 2121. Each quintuplet gоes оn a spaceship journey that takes T years, as measured by a clock in each spaceship. During the journey they travel at a constant speed v, as measured on earth, except during the relatively short acceleration phases of their journey. Rank these quintuplets on the basis of the year on Earth when they return from their journey. A. T=10 years, v=0.8c B. T=20 years, v=0.4c C. T=10 years, v=0.4c D. T=5 years, v=0.2c E. T=20 years, v=0.8c
