Activities :
Find out the seven fundamental units of system international . Also , indicate symbol of each unit and name the physical quantity it measures .

Complete the paragraph: in physics, square is the rate of doing work or, i.e., the amouth of energy trasferred or converted per unit time. In the international system of Units, the unit of power is the square , equal to one square per second. Power is a square quantity that requires both a change in the physical system and a specified tiem interval in which the change occurs. But more square is needed when the work is done in a shorter amount of time.

Explain with example, how is dimensional analysis used to convert the unit of a physical quantity from one system to another system of units.
