alleryStart learning →A swimmer floats because the forces underneath are larger. This is due to:
AMore warmth
BExtra salt
CGreater depth
DHigher speed
Answer & Solution
Correct answer: C. Greater depth
1. Pressure in a fluid varies with how deep you go.
2. The forces on a submerged body are larger underneath.
3. That is due to greater depth.
4. The result is a net upward or buoyant force balanced by the swimmer's weight.
