Thinking of school exam... I had plained to make a study timetable. Purposely plained to do it because I didn't really had enough time to study and also can finish all the school work given by school teacher on time. I will try my best to make the study timetable as soon as possible... because I hate thing done in last minute ! ! I will post my study timetable when it done :D
Things that I want to share today is the knowledge that I had learnt during the Physics class today... which is Pascal's Principle . This chapter were so hard , especially the calculation... Zzz
Before the lesson start, Physics teacher got tell us Pascal's Principle state that pressure applied to an enclosed fluid is transmitted undiminished to every part of the fluid, as well as to the walls of the container .But according to the internet, it state... (enjoy your reading)
Pascal's Principle states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container
A container, as shown below, contains a fluid. There is an increase in pressure as the length of the column of liquid increases, due to the increased mass of the fluid above.
For example, in the figure below, P3 would be the highest value of the three pressure readings, because it has the highest level of fluid above it.
If the above container had an increase in overall pressure, that same added pressure would affect each of the gauges (and the liquid throughout) the same. For example P1, P2, P3 were originally 1, 3, 5 units of pressure, and 5 units of pressure were added to the system, the new readings would be 6, 8, and 10.

Thanks for reading : D
