1.Units, Dimensions and Measurement
easy
The dimensions of power are
A${M^1}{L^2}{T^{ - 3}}$
B${M^2}{L^1}{T^{ - 2}}$
C${M^1}{L^2}{T^{ - 1}}$
D${M^1}{L^1}{T^{ - 2}}$
Solution
(a) Power = $\frac{{{\rm{Work done}}}}{{{\rm{Time}}}} $$= \left[ {\frac{{M{L^2}{T^{ – 2}}}}{T}} \right] = [M{L^2}{T^{ – 3}}]$
