Question

the high point of human -5 is 7.6 X 10 negative 22 / seconds and the half line of healing -9 is 7 x 10 negative 21 / seconds approximately how many times greater is the half line of helium -9 then that feeling -5

Answer 1

We will solve as follows:

`x(7\cdot10^(21))=(7.6\cdot10^(22))\Rightarrow x=(7.6\cdot10^(22))/(7\cdot10^(21))\Rightarrow x\approx10.85\Rightarrow x\approx11`

So, the half-life of helium-9 is approximately 11 times greater than the half-life of helium-5.
