A) \[~3.6\times {{10}^{26}}\]
B) \[0.36\times {{10}^{26}}\]
C) \[36\times {{10}^{26}}\]
D) \[0.0036\times {{10}^{26}}\]
Correct Answer: B
Solution :
[b] \[\frac{m}{t}=4\times {{10}^{8}}kg{{s}^{-1}}\] \[E=m{{c}^{2}}\] \[\Rightarrow \,\,\,\,\,\,\,\,\frac{E}{t}=\left( \frac{m}{t} \right){{c}^{2}}\Rightarrow \frac{E}{t}=4\times {{10}^{8}}\times 9\times {{10}^{16}}\] \[\Rightarrow \,\,\,\,\,\,\,\,\,\,\frac{E}{t}=3.6\times {{10}^{25}}J{{s}^{-1}}\Rightarrow \frac{E}{t}=3.6\times {{10}^{25}}W\]
