When two physical quantities are multiplied together, the result may be either a scalar quantity or a vector quantity. Which combination of two quantities gives a scalar quantity?
- A(force) \times (displacement of an object in the direction of the force)
- B(mass) \times (acceleration of the mass)
- C(pressure) \times (area on which the pressure acts)
- D(velocity) \times (time for which an object has that velocity)
