Question

please help me... I have to submit this assignment​

Answer 1

a) The cylinder floats in the sea because it contains air and the density of air is less than the density of water.

b) The volume of water displaced is 1.2 X 0.8 m^3. This supports 1.8 X 0.8 m^3 of material comprising the cylinder. Down force is 1.2 X 0.8 X 1020 X 9.81 N

Upforce = 9606 N
