Which of the following lists contains scalar quantities only?
Correct answer: B. Mass, volume, electrical potential, kinetic energy
- A. Mass, acceleration, temperature, kinetic energy
- B. Mass, volume, electrical potential, kinetic energy
- C. Acceleration, temperature, volume, electric charge
- D. Momentum, electric intensity, density, magnetic flux.
Explanation
A scalar quantity contains only magnitude and no direction, making options B the correct answer. Mass, volume, and electrical potential are all examples of scalar quantities as they can be fully described by their magnitude alone. Kinetic energy is also a scalar quantity due to the mathematical relationship between mass and velocity. Options A, C, and D include vector quantities, such as acceleration, momentum, and electric intensity, which have both magnitude and direction, making them incorrect choices for this question.
