A floating platform is moved between two liquids. At its maximum permitted immersion, it displaces 0.40 m3 of liquid in either liquid. The platform is at rest when floating. The densities of the liquids are shown in the table. Take g=10 N/kgg=10\ \mathrm{N/kg}g=10 N/kg.
| Liquid | Density in kg/m3\mathrm{kg/m^3}kg/m3 |
|---|---|
| X | 1000 |
| Y | 1100 |
Calculate how much more mass of equipment the platform can carry in liquid Y than in liquid X.
