Final answer:
The symbol that is correct for the given expressions is A) > because the magnitude of force A must be greater than the magnitude of force C. In the second question, none of the given symbols are correct because none of the equations equal to 12.
Step-by-step explanation:
The symbol that is correct for the given expressions is A) > because the magnitude of force A must be greater than the magnitude of force C, so A > C. In the second question, the symbol that is correct is d. None of the above because the given equations represent different values and none of them equal to 12. In the third question, the symbol that is correct is C. both of the above because both a person standing up from a seated position and a car accelerating while driving involve changes in position or speed. In the fourth question, the symbol that is correct is b. A negative sign (-) because by convention, an object moving downward is assigned a negative sign. Finally, the symbol that should be used in the fifth question is = because the question is asking for the correct symbol to use as a placeholder in an equation.
