This document contains 13 multiple choice questions related to physics. The questions cover topics such as the branch of science that deals with matter and energy (physics), units of distance (light year), dimensional formulas (Planck's constant), dimensions of kinetic energy and momentum, least count calculations for vernier scales, units of electron volt (energy), dimensional analysis, unit conversions (inches to meters), ways to express error, uses of static analysis, and calculating density to an appropriate number of significant figures.
