Here are the solutions to the questions: a) The unit of speed is m/s. The unit m/s^2 is the unit of acceleration. A student confusing the unit of speed with the unit of acceleration indicates a misunderstanding of the fundamental concept of speed versus acceleration. This is a conceptual error. The correct option is Conceptual error. b) A Newton (N) is the SI unit of force. According to Newton's second law, force (F) is equal to mass (m) times acceleration (a), so F = ma. The SI unit for mass is the kilogram (kg). The SI unit for acceleration is meters per second squared (m/s^2). Therefore, 1 Newton is equivalent to: 1 N = 1 kg · ms^2 The correct option is 1 kg · m/s^2. c) The seven SI base quantities are: length, mass, time, electric current, temperature, amount of substance, and luminous intensity. Electric current is an SI base quantity. Temperature is an SI base quantity. Force is a derived quantity, defined as mass times acceleration (kg · m/s^2). It is not a base quantity. Amount of substance is an SI base quantity. The correct option is Force. What's next?
