Question

Water pressure in a lake is greater __________. a. at the bottom b. at the surface c. at any point, for pressure is the same d. throughout midway to the bottom

Answer 1

Answer:

The correct answer  a

Explanation:

In the fluid pressure is a measure of force per unit area, in this case force is the weight of the fluid that increases as we descend. Therefore, the pressure increases with the depth of the fluid.

The correct answer  a

Answer 2

Answer:

a. at the bottom

Explanation:

Since water at the bottom of the lake is under pressure by all the water molecules above it plus atmospheric pressure. It is no doubt that the pressure at the bottom of the lake is larger than pressure in the middle and at the surface of the lake.
