Answer:
(i) W = 8.918 N
(ii)
(iii) d = 9.1 cm
Explanation:
Part a)
As we know that weight of cube is given as
here we know that
now the mass of the ice cube is given as
now weight is given as
Part b)
Weight of the liquid displaced must be equal to weight of the ice cube
Because as we know that force of buoyancy = weight of the of the liquid displaced
So here volume displaced is given as
Part c)
Let the cube is submerged by distance "d" inside water
So here displaced water weight is given as
so it is submerged by d = 9.1 cm inside water
