Question

Give some examples of derived quantities and express them in the form of base quantities

Answer 1

Base Quantity (Symbol)                  Base Unit (Symbol)Length (l)                                        metre (m)Mass (m)                                        kilogram (kg)Time (t)                                          second (s)Electric current (I)                       ampere (A)  (2013 P1 Q1)Temperature (T)                             kelvin (K)SI has recognized some physical quantities as base quantities and others as derived quantities
erived Quantity (Symbol) Formula            Derived Unit (Special Name)·        Force (F)                     Mass x Acceleration     kg ms-2 (newton, N)·        Pressure (P)                 Force/Area                   kg ms-2/m2 (pascal, Pa)·        Frequency (f)                1/Period                       1/s = s-1 (hertz, Hz)·        Work (W)                    Force x Displacemt       N x m (joule, J)·        Power (P)                    Work/Time                   J/s (watt, W)  
Electric charge (Q)        Current x Time                A s (coulomb, C)hope it helps
