Physics has an important role in our life. Without physics and the work of
physicists, our modern life would not exist. Using physics, people created machines,
instruments and some different divices from the crudest to the most modern aspect.
Techology is developed more rapidly, more modern day by day.
Moreover, all other natural sciences- example chemistry, biology, medicinedepend
upon physics for the foundations of their knowledge.
An equation is a statement of equality: Whatever is on the left-hand side of any equation is equal to whatever is
on the right-hand side. The symbols in an algebraic equation usually cannot have arbitrary values if the equality
is to hold. To solve an equation is to find the possible values of these symbols. The solution of the equation
5x − 10 = 20 is x = 6 because this is the only value of x for which this equation is a true statement.
The algebraic procedures that can be used to solve an equation are all based on the principle that any
In every society, there is a need to be educated. The reasons can vary from learning more about geography to understand how to set up a profitable small business. Some students can go to school to become more environmentally aware and to learn more about small business management. Schools can provide a knowledge of subjects such as Geography. Case in point, a student studying Physical Geography can learn about the mountains formed how, thus developing in him a deeper respect for the environment.
Microelectromechanical systems (MEMS) have played an increasingly important
role in sensor and actuator applications. And its key contribution is that it has enabled
the integration of multi-components (i.e., electronics, mechanics, fluidics and etc) on a
single chip and their integration has positive effects upon performance, reliability and
cost. Compared to conventional electrostatic, thermal or magnetic actuating schemes,
piezoelectric MEMS inkjet has the advantages of lower power consumption, lower
voltage operation and relatively larger driving force....
