Power is force times velocity, with constant velocity across options

Steps:

• Velocity v = distance/time = 1.0 m / 10 s = 0.1 m/s for all diagrams.
• Work done W = force F × distance d = F × 1.0 m.
• Power P = W/time = F × d / t = F × v.
• Highest F gives highest P; option A has F = 12 N.

Why A is correct:

• Largest force (12 N) multiplies same v (0.1 m/s) to maximize P = F v.

Why the others are wrong:

• B: 8 N yields lower P than 12 N.
• C: 10 N yields lower P than 12 N.
• D: 4 N yields lowest P.

Final answer: A
