Here are the answers to your questions:

  1. False - Magnitude is the size or amount of a quantity, such as a force, but does not measure its strength by itself without context.

  2. a. balanced forces - In a diagram (not provided), if the forces acting on an object are equal and opposite, they are balanced.

  3. a. cancel out - When two forces of equal magnitude are exerted in opposite directions, they cancel each other out.

  4. True - Forces in opposite directions do subtract from each other when calculating net force.

  5. c. A represents vector and B represents scalar - Assuming A is a quantity with direction (e.g., velocity) and B is a quantity without direction (e.g., mass).

  6. c. subtract - When vectors point in opposite directions, you subtract the smaller magnitude from the larger magnitude.

  7. (The answer cannot be provided without the actual diagrams mentioned. Please provide those details for accurate assessment.)

  8. d. A stationary book on the table must be picked up in order for it to move - This exemplifies Newton's First Law, which states that an object at rest will remain at rest unless acted upon by an external force.

Please provide any diagrams or additional context if needed for questions that require visual interpretation.
