A sample of an unknown material appears to weigh 270 N in air and 165 N when immersed in alcohol of specific gravity 0.700.
(a) What is the volume of the material?

(b) What is the density of the material?

  • Physics Help Please -

    YOu know immersed, its bouyancy force is equal to the weight of the displaced medium; Archimedes discovered that. change specific gravity to density.

    270-165=densityalcohol*volumedisplaced*g

    solve for volume displaced, duh, double duh, that is the volume

    density= mass/volume= 270/g * 1/volume in kg/m^3
