You need to determine the density of an unknown liquid and decide to perform an experiment. You notice that a wooden block floats in this liquid with 4.6 cm of the side of the block submerged. Then you place the same block in water and notice that it also floats but with 5.8 cm submerged. What is the density of the unknown liquid.

pu = 1260.9kg/m^3

the density of the unknown liquid is 1260.9kg/m^3

Explanation:

The density of a liquid is inversely proportional to the volume (height) of object submerged in it.

High density liquid possess higher buoyant force preventing objects from submerging.

p ∝ 1/V ∝ 1/h

since V = Ah

pu/pw = hw/hu

pu = pwhw/hu

Where;

p = density

h = height submerged

pu and pw is the density of unknown liquid and water respectively

hu and hw is the height of object submerged in unknown liquid and water respectively

pw = 1000kg/m^3

hu = 4.6cm = 0.046m

hw = 5.8cm = 0.058m

Substituting the given values;

pu = 1000×0.058/0.046

pu = 1260.9kg/m^3

the density of the unknown liquid is 1260.9kg/m^3

if you answer my question i will answer yours

because if the tool that you are using is not balanced it there would be false mass.
