Question

5 which of the following involves an unbalanced force? 53 ints multiple choice 00:25.30 a stationary book exerts a force on a table a person pushes on a table that does not move a force acting between two objects results in the acceleration of one

Explanation:

Unbalanced forces cause acceleration. A stationary book on a table and a person pushing on a non - moving table are examples of balanced forces where the net force is zero and there is no acceleration. When a force between two objects results in the acceleration of one, it indicates an unbalanced force as per Newton's second law ($F = ma$, non - zero acceleration means non - zero net force).

Answer:

a force acting between two objects results in the acceleration of one
