Imagine that a reactor converts all given mass into energy and that it operates at a power level of 109 watt. The mass of the fuel consumed per hour in the reactor will be : (velocity of light, c is \[3\times {{10}^{8}}m/s\])

• A. \[0.96\text{ }gm\]
• B. \[0.8\text{ }gm\,\]
• C. \[4\times {{10}^{-2}}gm~~~~~\]
• D. \[6.6\times {{10}^{-5}}gm\]
