Pi ©theexpertta.com 33% Part (a) Enter an expression for the distance d, in terms of the defined quantities - 33% Part(b) If the density of the cube is equal to the density of the liquid how high surface of the liquid? n meters will the top ofthe be be a re the Grade Summary Deductions Potential d= 0.0436 80%

Explanation / Answer

here,

B)

if the density of liquid is equal to the density of cube

pc = pl

let the height above the liquid be d

equating the forces

m * g = ( L^2 * ( L - d)) * g * pl

L^3 * pc * g = ( L^2 * ( L - d)) * g * pl

L - d = L

d = 0

the top of cube is 0 m above the water surface
