"Detailed Physics Exercises, Volume 1" #Books #BOOK #Computer #IT #NaturalScienceAndTechnology #Physics #PhysicsExercises I used to use this before, but I stopped and have been storing it. There was some writing in pencil, but I erased it as much as possible with an eraser. There may be some that haven't been erased. Since it was used, there is some dirt from use. Please understand that this is a used item. Please refrain from purchasing if you are sensitive to such things.
