This document is a physics assignment from Sharda University for the 2012-2013 session on Engineering Physics. The assignment contains 5 questions worth a total of 10 marks, with each question worth 2 marks. The questions cover defining inertial and non-inertial frames with examples, writing the postulates of special relativity, describing the Michelson-Morley experiment and expected fringe shift calculation, calculating the speed of a rocket from its observed length contraction, and calculating the velocity needed for a clock to appear 30 seconds slow per day to an observer.

- 1. SHARDA UNIVERSITY GREATER NOIDA Session: 2012-2013 PHY 109: Engineering Physics Assignment-1 Issue date: 24/08/2012 Marks: 10 (2 marks for each question) Q1. Define the following terms: (a) Inertial frame with example (b) Non-inertial frame with example Q2. Write the postulates of Special theory of Relativity. Q3. Describe the Michelson-Morley experiment with figure. Give the mathematical derivation for the expected fringe shift in this experiment due to ether. Q4. A rocket ship is 50 meters long. When it is flight, its length appears to be 49.5 meters to an observer on the ground. Find the speed of the rocket. Q5. A clock measures the proper time. With what velocity it should travel relative to an observer so that it appears to go slow by 30 seconds in a day?
