DIRECTION: Relate concepts to problem solving, analyze the effect and evaluate the validity of the application of relativity. Write conceptual symbols with correct identification, formula and correct solution on a clean paper. Scan and upload in MOODLE as pdf document. Q1. 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: 1 x 5 = 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)
