What are the action and reaction forces at work in this picture? a the book is pushing on the table and the table is pushing on the book b gravity is pulling the book downward c friction is pushing up and gravity is pulling down d the flower vase is pushing up and gravity is pulling down
The correct answer is: c friction is pushing up and gravity is pulling down.
Explanation: In the given picture, the book is resting on the table. The force of gravity acts downward, pulling the book towards the ground. At the same time, the table exerts an equal and opposite force of friction on the book, pushing it upwards. These two forces, gravity and friction, are action and reaction forces at work in this scenario. The flower vase and its interaction with gravity are not relevant to this picture.
