Dimensional analysis is helpful for__________________?
Correct answer: D. Only A and B are correct
- A. Deriving a possible formula
- B. Checking the homogeneity of a physical equation
- C. Verification of laws
- D. Only A and B are correct
Explanation
Dimensional analysis can suggest a possible formula and can test whether both sides of an equation have the same dimensions. It cannot prove a physical law or determine dimensionless constants, so option c is the usual trap for confusing consistency with complete verification.

About Work-Energy Theorem
The work-energy theorem states that the net work done on an object equals its change in kinetic energy. Questions involve positive and negative work, variable forces and force-displacement graphs, acceleration or deceleration, and the difference between this theorem and conservation of mechanical energy, which also requires attention to potential energy and non-conservative work.
