SUMMARY

The density of a block that is 35% submerged in a liquid with a density of 2.5 g/cm³ is calculated to be 0.875 g/cm³. This conclusion is derived from the relationship between the submerged volume and the densities of the block and the liquid, using the formula d = m/v. The calculation involves setting up a proportion based on the submerged volume percentage, confirming that the approach is valid and the result is accurate.

PREREQUISITES
  • Understanding of density and its formula (d = m/v)
  • Basic knowledge of fluid mechanics and buoyancy principles
  • Ability to set up and solve proportions
  • Familiarity with units of measurement (g/cm³)
NEXT STEPS
  • Study Archimedes' principle and its applications in buoyancy
  • Learn about the relationship between density and buoyancy in different fluids
  • Explore the effects of temperature and pressure on liquid density
  • Investigate how to calculate density for irregularly shaped objects
USEFUL FOR

Students in physics or engineering, educators teaching fluid mechanics, and anyone interested in understanding buoyancy and density calculations.

Homework Statement



if I have a block of unknown density and if it is 35% submerged in a liquid of density 2.5g/cm^3
what is the density of the block

Homework Equations


d=m/v

The Attempt at a Solution


I thought that if the block was 100% submerged just under the surface, its density would equal that of the liquid.
Since it is 35% submerged, i thought i would approach it this way.
2.5/100=x/35
87.5=100x
x=0.875g/cm^3
Is that correct?

That looks good to me :smile:
 
Thanks.
