Question #207931

A homogeneous wood cylinder of height h and density

p = 950 kg/m^3 when immersed in a liquid floats so that the emerging part is equal to 3⁄4 h. Calculate the density of the liquid.

Expert's answer

"\\rho g A h=0.75\\rho_w g A h\\\\\n\\rho =0.75\\rho_w=0.75(950)=712.5\\frac{kg}{m^3}"
