Which condition on the operator is broken allowing the eigenstates not to be orthogonal?. Why is this condition sufficient to ensure orthogonality when

We will in this problem consider a pendulum of mass m at the end of a massless rod of length l moving about a pivot P. There is a gravitational field g pointing downwards in

Suppose we have a two-dimensional electron density ρ, what magnetic field B = B 0 will ensure that all electrons will be in the first Landau level. Plot the Fermi energy — the energy

(a) Derive the 3D density of states g(E), find the Fermi energy in terms of the electron density n, and find the average electron energy at T = 0 K in the free electron model..

b) Anta at du har for lite glukose i blodet. Hormonet vasopressin skilles da ut og binder seg til sine reseptorer på leverceller. I levercellene blir lagrene av glukose i form

c) Forklar hvordan cytoskjelettet bidrar til å forankre celler i ekstracellulær matrix Alle delspørsmål vektlegges likt.. Dette aktiverer c-AMP som igjen stimulerer transkripsjon
