why will all of the books in this line of books fall over? check all that apply. each book is too close to the next book. each book pushes the next book. each book transfers energy to the next book. each book pulls the next book. each book does work on the next book.
Answer
Brief Explanations:
When one book in the line is pushed and falls, it exerts a force on the next - book, pushing it. This force transfer is a form of energy transfer and also involves work being done on the next book. Books don't pull each other in this context, and being close is not the main reason for the falling - over sequence.
Answer:
Each book pushes the next book. Each book transfers energy to the next book. Each book does work on the next book.
