In a chain reaction that includes a branching step, the number
of chain carriers doubles once every 1 x 10 -8 seconds.
How long will it take for the number of chain carriers to increase
by a factor of 1012
A: 0.012 seconds
B: 12 x10-4 seconds
C: 104 seconds
D: 4 x10-7 seconds
Homework Answers
time = factor value x number of chains every second
= 10^12 x 1 x 10^-8
= 10^4 seconds
answer : C) 10^4 seconds
