Answer:
The answer is "0.0000190 and 2.7 J".
Explanation:
Given:
by putting the value into the above formula so, the value is 2.7 J
Explanation:
Formula to calculate how many particles are left is as follows.
N =
where, = number of initial particles
l = number of half lives
As it is given that number of initial particles is and number of half-lives is 3.
Hence, putting the given values into the above equation as follows.
N =
=
=
or,
Thus, we can conclude that particles of radioactive nuclei remain in the given sample.
In five hours we've gone through 5 half lives so the answer is:
particles
