Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What quantity does the following equation calculate:density x gravitational field strength x depth
A
water pressure at a given depth
B
force of water at a given depth
C
velocity of water at a given depth
D
energy of water at a given depth
Explanation: 

Detailed explanation-1: -The pressure in a liquid at a given depth is called the hydrostatic pressure. This can be calculated using the hydrostatic equation: P = rho * g * d, where P is the pressure, rho is the density of the liquid, g is gravity (9.8 m/s^2) and d is the depth (or height) of the liquid.

Detailed explanation-2: -dpdy=−g. This equation tells us that the rate of change of pressure in a fluid is proportional to the density of the fluid. The solution of this equation depends upon whether the density is constant or changes with depth; that is, the function (y).

Detailed explanation-3: -To measure the density of a liquid you do the same thing you would for a solid. Mass the fluid, find its volume, and divide mass by volume.
