Question

part 9 - mechanical comprehension question 9 of 15 what is the force acting on the log to keep it afloat? a friction b torsion c inertia d buoyancy click the button or type the letter next to your answer. next >>

Explanation:

To determine the force keeping the log afloat, we analyze each option:

• Option A: Friction is a force opposing motion between surfaces, not related to floating.
• Option B: Torsion is a twisting force, irrelevant to buoyancy.
• Option C: Inertia is the tendency to resist motion change, not a floating force.
• Option D: Buoyancy is the upward force exerted by a fluid (like water) that keeps objects afloat, matching the log's situation.

Answer:

D. buoyancy
