A) 1000
B) \[2\times {{10}^{8}}\]
C) \[3.125\,\times {{10}^{16}}\]
D) 931
Correct Answer: C
Solution :
Energy \[\overset{0}{\mathop{A}}\,\] \[\overset{0}{\mathop{A}}\,\] \[x={{x}_{0}}\sin 2\pi \left( nt-\frac{x}{\lambda } \right)\] Power \[\lambda =\frac{\pi {{x}_{0}}}{4}\] Rate of disintegration \[\lambda =2\pi {{x}_{0}}\] \[\lambda =\frac{\pi {{x}_{0}}}{2}\] \[\lambda =4\pi {{x}_{0}}\]per second
