So in this problem, we know the uncertainty off the energy is Ah one mega TV. So according to the Hesburgh on Sydney Law, we have that e that a t ah is greater or equal to H over full pie. We're here because we want to find out the smallest of my time. So we we used equal case so that a t equal h over four pi times that eat right So this you can do the calculation and find that 30 this morning the lifetime equal 3.3 times, 10 to the negative, 22 seconds.
