Discuss liquid pressure used as used in everyday occurrence. Define and discuss liquid pressure as force /area. Determine how the liquid pressure is due to the weight of the liquid and not the area on the bottom of the container. Convert pressure into mass x gravity/area which becomes density/volume x gravity /area. Using the knowledge of liquid pressure, discuss how everyday appliances, such as toilet bowls operate without external energy sources. Discuss siphon physical.
Discuss wave propagation, wave diagrams and how to determine velocity of a wave after determining a formula which can be used.
