Physics with Answers contains 500 problems covering the full range of introductory physics and its applications to many other subjects, along with clear, step-by-step solutions to each problem. No calculus is required. Students often have difficulty in solving practical problems after a subject is introduced in class. This book bridges that gap - it contains every type of problem likely to be encountered at this level, so by attempting these exercises and learning from the solutions, students will gain confidence in solving class problems and improve their grasp of physics. The book is split into two parts. The first contains the problems, together with useful summaries of the main results needed for solving them. The second part gives full solutions to each problem, often accompanied by thoughtful comments. Subjects covered include statics, Newton's Laws, circular motion, gravitation, electricity and magnetism, electric circuits, liquids and gases, heat and thermodynamics, light and waves, atomic physics, and relativity. The problems are drawn from many fields, including physics, chemistry, biology, engineering, medicine, and architecture.

Observations of distant supernovae have provided startling evidence that the expansion of the Universe may be accelerating, rather than decelerating. If this result is verified by future studies, it has profound implications for cosmology. The reliability of this finding and its implications for both the study of supernovae and cosmology are the subject of this exciting volume. Based on a conference at the University of Chicago, this timely volume, originally published in 2000, presents articles by leading experts on the theory of Type Ia supernovae, observational astronomy, and cosmology. It examines the observational data, the nature of the likely progenitor binary systems, the outburst mechanisms of Type Ia supernovae events, and the cosmological implications. This is a unique and wide-ranging review of one of the most dramatic and controversial results in astronomy in recent decades. It makes fascinating reading for all researchers and graduate students.
