A book on a table is being pushed to the left with an applied force of 12 newtons. The book is accelerating to the left.Which statement best describes the magnitude of the friction force acting on the book?Select one:The magnitude of the friction force is greater than 12 N.highlight_offThe magnitude cannot be characterized without knowing the friction coefficient.highlight_offThe magnitude of the friction force is less than 12 N.highlight_offThe magnitude of the friction force is equal to 12 N.

This image shows a book on a table, the normal force acting on the book, and the force being applied to the book. The book is initially at rest, with a static friction coefficient of 0.70 between the book and the table. What happens to the book once force is applied?Select one:The book accelerates to the left.highlight_offThe book moves at a constant velocity to the right.highlight_offThe book remains at rest.highlight_offThe book accelerates to the right.highlight_off

The figure below shows the forces exerted on an object that is sliding on a horizontal surface:Fg: the gravitational force of 40 N,Fn: the 40 N normal force exerted by the surface, andFf: a frictional force exerted to the left.If the coefficient of friction between the block and the surface is 0.15, then which of these most nearly represents the acceleration of the block?   Group of answer choices2 m/s2 to the left1.5 m/s2 to the left2 m/s2 to the right1.5 m/s2 to the right
