A) \[0.02\text{ }W\]
B) \[400\text{ }W\]
C) \[5\times {{10}^{-10}}W\]
D) \[0.2\text{ }W\]
Correct Answer: A
Solution :
We know that \[Power=pressure\times volume\text{ }per\text{ }second\] Given, pressure \[=20,000\text{ }N{{m}^{2}},\] volume \[=1\text{ }cc={{10}^{-6}}\text{ }{{m}^{3}}\] \[\therefore \] power \[=20,000\times {{10}^{-6}}\] \[P=0.02W\]
