Question

Which of the following unit is derived unit?

Answer 1

Answer:

1.  Area = l . w

            = m.m

            = m^2

2.  Volume = l . w. h

                  = m .m .m

                  = m^3

3. Speed= d / t

                  = m/s

                  = m/s

4. Acceleration = v / t

                         = m / s . s

                         = m / s^2

5. Work done = F . d

                       = N .m

                       = Nm

Explanation:

Derived units

- are derived from fundamental units

- are a product or ratio of fundamental units
