How does pressure relate to force?
force/area
what is the relationship b/w liquid pressure and the depth of a liquid? B/w liquid pressure and weight density
liquid pressure is propotioanl depth and to weight density
how deos teh water pressure 1 m below the surface of a small pond compare w/ the water pressure 1 m below the surface of a huge lake?
pressures are the same at the same depthw
why does buoyant force act upward on an objects submerged in water
buoyant levels were eqial
how does volume of a completely submerged object compare w/ the volume of water dispalced
both volumes are the same
distinguish between an immersed and submerged body
a submered body is beneath the surface
if 1-L container is immersed halfway into water wht is the volume of water displaced? buoyant force?
1/2 L, bf=5 N
what is the condition in which the buoyant force of an object does equal weight of the object
when an object floats, its bf=w
an object denser than water will ____. An object less dense that water will ___. An object has the same density as water will ___
sink, float, neither
