pressure​

Answer 1

Answer:

force

Explanation:

decided whether an object will pressure force

Answer 2

Answer:

1. The density of an object and the liquid in which it is immersed determine whether it sinks or floats. An object that is denser than a liquid will sink into it, whereas a less dense thing would float.

II. Exerted Pressure  = F/ A

Explanation:

Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

Pressure exerted by a force depends on the magnitude of the force and surface area.

Exerted Pressure  = F/ A

                 = Force / Area

where F = magnitude of Force

            A= Surface Area

Units of pressure is  Pascal

Units :   N/m²,  J/m³
