Question

select the correct answer. what type of force does a backpack exert on the body’s back and hips? a. tension b. compression c. flexion d. extension

Explanation:

To determine the force a backpack exerts on the body's back and hips, we analyze each option:

• Option A (tension) involves pulling forces, not typical for a backpack's weight pressing on the body.
• Option B (compression) is a force that pushes or squeezes, which matches the backpack's weight pressing (compressing) the back and hips.
• Option C (flexion) is a joint movement (bending), not a force type.
• Option D (extension) is also a joint movement (straightening), not a force type.

Answer:

B. compression
