3. (a) How many paths are there from the point (0, 0) to the point (110, 111) in the plane such that each
step either consists of going one unit up or one unit to the right? (b) How many paths are there from (0,
0) to (210, 211), where each step consists
5. Give a story proof that Pn k=0 "n k # = 2n. 6. Give a story proof that (2n)! 2n n! = (2n ! 1)(2n ! 3) 3
1. 7. Show that for all positive integers n and k with n " k, n k + n k ! 1 = n + 1 k , doing this

The logarithms are in base 10, R is expressed in ohms, and T in Kelvin. a) In a liquid helium cryostat, the
resistance is measured to be 218 ohms. What is the temperature? b) Make a loglog graph of R as a
function of T in the resistance interval between
Imagine that we are given the function A(x,y) = 2xy2 and are instructed to integrate it with respect to x,
from x = 0 to x = 1. This presents no difficulty: Z 1 0 A(x,y) dx = x 2 y 2 1 0 = y 2 . It is clear that y
must be treated as a constant during the
The sign of the work done depends on the direction in which the piston is moved. The work done on the
system will be positive if the displacement is in the same direction as that of the applied force F, and it
will be negative if the displacement is in th
We begin this interlude by introducing the twodimensional plane with coordinates x and y. To denote an
infinitesimal displacement in the x direction we use dx, and dy denotes an infinitesimal displacement in
the y direction. Multiplying an infinitesimal
The general idea is that microscopically, temperature is defined to be a measure of the kinetic energy of
our gas molecules. More precisely, temperature is defined by the statement 1 2mv2 = 3 2 kT, where k =
1.38 1023 J/K is the Boltzmann constant. Using
A thermodynamic system is always confined within some boundary. Outside this boundary is the
systems surroundings. The combination system + boundary + surroundings is called the universe. (The
Universe is a thermodynamic system without a boundary. Think a
