A) \[277.7\times {{10}^{-5}}\,joule\]
B) \[277.7\times {{10}^{-6}}\,joule\]
C) \[277.7\times {{10}^{-4}}\,joule\]
D) \[27.77\times {{10}^{-4}}\,joule\]
Correct Answer: A
Solution :
[a] \[{{W}_{H}}=VA\,ft=\frac{m}{d}\,\,Aft\] \[=\frac{0.6}{7.8\times {{10}^{3}}}\times 0.722\times 50=277.7\times {{10}^{-5}}\,Joule\]You need to login to perform this action.
