Answer:
Explained
Explanation:
The minimum energy required by a photon to create a electron-positron pair must be equal to the sum of rest mass energies of both electron and positron.
therefore E= 2m_ec^2
=2×0.511 MeV
=1.02 MeV
Below this , the process would not occur. So, in the energy range of > 1.02 MeV
The most dominant process will be in pair production.
At the range of 200 KeV to 3 MeV, The most dominant Process is compton Scattering.
below 200 KeV , Photo electric effect is more dominant.
Bella’s average velocity is about 0.693 meters per second.
To find the average velocity, you must divide the distance by the change in time, which should look like v=d/t
Here is how you set up the equation-
v=6.1/8.8
Once you divide 6.1 meters by 8.8 seconds, you should get a number that looks like 0.69318182.... however, I just rounded it to 0.693 meters per second. You can round it to whatever you like.
Hope this helped! If you have any questions about what I mentioned in my answer or explanation, feel free to comment on my answer and I’ll try to get back to you!
