As the book falls toward the ground, the time interval between floors becomes smaller, because the book keeps gaining speed and falling faster. That's the acceleration of gravity at work.

Answer:

B) the time interval between floors becomes less each time.

Explanation:

The time interval between floors becomes less each time. Because gravity is accelerating the book, the velocity increases between each floor. This means that the same distance will be covered in less time.


By the way, your book is not a good thing to throw out the window.
