From the point of view of observer 1 who is in an S frame where v = 0c, one twin is travelling where v = 0.866c and returning. From this frame, calculate Y. (a) Identify the concepts and its symbols (Point system: 2 x 5 = 10 marks) (b) Correct formula (Point system: 1x5= 5 marks) (c) Solution (Rubric 5 marks) Q2. There are three stars. The left star, v= 0.903c and the right star where v is the same as the left star. Both approaching the center star at 0.9 times the speed of light. In this view, find Y. (a) Correct formula (Point system: 1 x 10 = 10 marks) (b) Identify the conceptual symbols and identify (Point system: 3 x 1 = 3 marks) (c) Solution (Rubric 5 marks) (d) Evaluation of Y (Rubric 2 marks) Rubric Q1/Q2c: 5-correct formula, substitution, step-by-step calculation, actual computed value as final answer; 4-correct formula, step-by-step calculation and actual computed value; 3- correct formula, substitution and actual computed value; 2 - correct formula and actual computed value as final answer; 1-correct actual computed value as final answer; 0-wrong formula/wrong substitution/wrong actual computed value as final answer/no answer Q2d: 2 - evaluation of Y with reference to the correctness of the computed answer; 1- correct evaluation of Y with reference to the correctness of the computed answer; 0-wrong computed answer, wrong evaluation of Y, or no answer
