All of the following is/are scalar quantities except:
Correct answer: D. Force
- A. temperature
- B. Density
- C. Volume
- D. Force
- E. Speed
Explanation
Scalar quantities are those that only have magnitude, unlike vector quantities that have direction as well as magnitude.Temperature, density, volume, and speed all have magnitudes only. Force, however, has magnitude as well as direction. Therefore, it is a vector.

About Vectors and Equilibrium
Vectors have magnitude and direction, unlike scalars, and are combined by head-to-tail or parallelogram methods. Work covers rectangular components, equilibrium when the resultant force is zero, the scalar product for work and projections, and the vector product for torque and cross-product direction using the right-hand rule.

In the following question, two statements numbered I and II are given. There may be cause and effect relationship between the two statements. These two statements may be the effect of the same cause or independent causes. These statements may be independent causes without saving any relationship. Read both the statements in question and mark your answer as: A. If statement I is the cause and statement II is its effect; B. If statement II is the cause and statement, I is its effect; C. If both the statements I and II are independent causes; D. If both the statements I and II are effects of independent causes; E. If both the statements I and II are effects of some common causes; I.
