Question 43
A nuclear fuel disintegrates as shown with time
9.10 am - 32 g
9.35 am - 16 g
10.00 am - 8 g
10.25 am - 4 g
And left at 11.40 am_____
Solution
The nuclear fuel disintegrates half of its value every 25 min.
So, at 10:50 it becomes '2g', at 11:15 it becomes '1g' and at 11:40 it becomes 0.5g
Hence, option D is the correct answer.
