The aim of the present collection of questions and problems is to develop practical skills during study of one of the fundamental sciences physics. The Collection is intended for the self-instruction of students of technical colleges. The best way to use it is to solve the problems while preparing for term exams. The Collection contains more than 400 questions and problems covering all the sections of the physics course. All questions and problems have detailed answers and solutions. For this reason the two main sections of the book Questions and Problems and Answers and Solutions have identical headings and numbering: each chapter in the first section has a corresponding chapter in the second and the numbering of answers corresponds to the numbering of problems. A special feature of the Collection is the drawings and diagrams for most of the questions and answers.
