Which of the following units is equivalent to the watt?
-
A.
kgms-2 -
B.
kgm2s-3 -
C.
kgm2s-2 -
D.
kgm2s-1
Correct Answer: Option B
Explanation
(Power = frac{text{Work done}}{time})
= (frac{Force times distance}{time})
= (frac{mass times acceleration times distance}{time})
= (frac{kg times m times m}{s^{2} times s})
= (kgm^{2} s^{-3})
