A ship of mass 1300 tonnes floats on sea water:

A ship of mass 1300 tonnes floats on sea water:
(i) What volume of sea water is displaced (Density of sea water is 1025kg/m³)
(ii) Suppose it sails from sea water to fresh water, what cargo must be removed so that the same volume of water is displaced? (Density of fresh water = 1000kg/m³

---

i)Mass of the ship = mass of water displaced

Mass of water displaced = 1300000kg
Volume of water displaced = Mass/Density
=1,300,000kg/1025kg/m³

= 1268.3m³


ii)Weight of ship – weight of cargo = upthrust in fresh water
13,000,000kg – W = weight of water displaced in fresh water
13000000 – W = (1268.3 x1000) x10
W = 13,000,000 – 12, 683,000
W = 31,7000N
Cargo removed = 317tonnes
