Water has a density of 1.0 g/cm3 and about 25 percent of the block is below water. what is a good estimate of the density of the block? a 0.25 g/cm3 b 0.50 g/cm3
c 0.75 g/cm3 d 1.0 g/cm3

A 0.25 g/cm3

Explanation:

At equilibrium, the buoyant force acting on the block (B, upward) is equal to its weight (W, downward):

where

is the water density

is the part of the volume of the block immersed in the water

g is the acceleration of gravity

is the density of the block

V is the volume of the block

Re-arranging the equation,

where we know:

, since the fraction of volume immersed is 25%

Substituting,

what are the statements? x

i think if it were me i whould divide 300 dide 15
