Dconsider a gas of n identical, non-relativistic, non-interacting spin 12 fermions (spin degeneracy gs 2), confined to move in a one-dimensional system of length l. b) find an expression for the fermi energy at t-0. c) find the total kinetic energy e of the gas at absolute zero. d) find the pressure exerted by the gas at t 0

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
