I have a few exercices (two) on Bravais lattices and I can’t figure it out about the best way to approach them. A few tips on the steps, or theories that I should base my resolution on would be helpful.
I also have another 2 exercices that approach particles collision times and the kinetic theory of gases.
By the way, the exercises I mention are attached.
If there is any helpull suggestion that allows me to solve this problems, I would be very happy.
