Let z1(m) denotes the canonical partition function for a particle of mass m in a volume v. the canonical partition function of two such particles if they single quantum are classical boltzmann particles is z2 cl z1(m)2. (a) calculate the canonical partition function z5(m) of two such particles if they spinless fermions are (b) use the classical approximation z1(m) = v/^3 where a the corrections to the energy e, and the heat capacity c due to fermi statistics.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.
