Here are the answers to your questions:
11. List 3 applications of pressure in fluids.
Hydraulic braking systems*: Pressure applied to a small piston is transmitted through fluid to a larger piston, multiplying the force to stop a vehicle.
Hydraulic lifts/jacks*: Used to lift heavy objects by applying a small force over a small area, which generates a larger force over a larger area.
Syringes*: Pressure is used to draw in or expel fluids.
12. State and explain 3 properties of a material.
Density*: This is the mass per unit volume of a material. It indicates how much matter is packed into a given space.
Elasticity*: This is the ability of a material to return to its original shape and size after being deformed by an external force.
Ductility*: This is the ability of a material to be drawn or stretched into a thin wire without breaking.
