List 3 applications of pressure in fluids.

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.
