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).
State Pascal's law. Give 2 applications of it.
Pascal's law states that pressure is transmitted equally in all directions when pressure is applied at a place on a liquid kept in a closed container.
Any two applications of it are:
