Question

give one word • pressure exerted by a stationary liquid _______. • force in a direction perpendicular to a given surface area _______. • a pair of forces whose resultant is zero _______.​

Answer 1

Answer:

1. Hydrostatic pressure.

2. Pressure.

3. Equilibrium forces.

Explanation:

1. Hydrostatic pressure: pressure exerted by a stationary liquid. It is simply the pressure in a liquid such as water at a specific depth.

Mathematically, hydrostatic pressure is given by the formula;

$H.P = rho * g * d$

Where:

• H.P is the hydrostatic pressure of a liquid.
• rho represents the density of a liquid.
• g is the acceleration due to gravity.
• d is the depth (height) of a liquid.

2. Pressure: it is the force in a direction perpendicular to a given surface area. Thus, it's typically measured in Newton per meters (N/m²).

Mathematically, pressure is given by the formula;

$Pressure = \frac {Force}{area}$

3. Equilibrium forces: a pair of forces whose resultant is zero. It is also referred to as balanced forces because the resultant of all the pair of forces acting on a body or system is at equilibrium (balanced).
