Define pressure. Give its SI unit.
The total force applied per unit area is called pressure.
Mathematically,
Pressure (P) = Force (F) / Area (A)
Its SI unit is pascal (Pa).
If a freely floating ship has a weight of 5*105 N, what will be the weight of water displaced by the ship?
The weight of water displaced by the ship will be more than its own weight i.e., 5*105because it is built in such a way that the weight of the water displaced by the ship is more than its weight itself. So that it will not sink in seawater
