A) \[{{10}^{6}}\]
B) \[{{10}^{8}}\sec \]
C) \[{{10}^{12}}\sec \]
D) \[{{10}^{16}}\sec \]
Correct Answer: C
Solution :
[c] Mass defect \[=3\times 2.014-4.001-1.007-1.008\] \[=0.026amu=0.026\times 931\times {{10}^{6}}\times 1.6\times {{10}^{-19}}J\]\[=3.82\times {{10}^{-12}}J\] Power of star \[={{10}^{16}}W\] Number of deuterons used \[=\frac{{{10}^{16}}}{\Delta M}=0.26\times {{10}^{28}}\] Deuteron supply exhausts in \[\frac{{{10}^{40}}}{0.26\times {{10}^{28}}}={{10}^{12}}s\]You need to login to perform this action.
