Which is true about the pressure of a fluid at a specific depth? A. It depends on the surface area of the fluid. B. It is exerted only in the downward direction. C. It depends only on the type of fluid. D. It varies with the total volume of the fluid.

c) depends only on the type of fluid

Explanation:

The pressure of a fluid at a specific depth is given by:

where

is the density of the fluid

g is the gravitational acceleration

h is the depth

We see that for a given depth h, the pressure of the fluid depends only on its density, so only on the type of fluid. Therefore, the correct choice is

a) depends only on the type of fluid

The other choices are wrong because:

b) the pressure is exerted in every direction

c) the pressure does not depend on the total volume of the fluid, but only on the depth h

b.

hope this : )

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
