This document appears to be an exam for a first year engineering physics course. It contains 18 multiple choice questions across two sections. Section A contains 10 questions worth 4 marks each, while Section B contains 4 out of 6 potential essay questions worth 10 marks each. The questions cover topics in physics including vectors, kinematics, dynamics, oscillations, thermodynamics, optics, electricity and magnetism. Students are instructed to show working, define key terms, derive equations, and apply concepts as needed to fully answer the questions.
