Jerry had been drinking all evening at the Bonger Bar and became visibly intoxicated. The bartender continued to serve him. Thereafter, Jerry left the Bonger Bar and, still visibly intoxicated, went to Gordon’s Restaurant, where he had another drink. While driving home from Gordon’s Jerry drove his car in the wrong lane and crashed head-on with another car. Both Jerry and the driver of the other car suffered serious injuries. Both sued Gordon’s and Bonger Bar. Who is liable to whom?

Consider a particle moving in two spatial dimensions, subject to the following potential:
V (x, y) = (
0, 0 ≤ x ≤ L & 0 ≤ y ≤ H
∞, otherwise.
(a) Write down the time-independent Schr¨odinger equation for this case, and motivate
its form. (2)
(b) Let k

2 and rewrite this equation in a simpler form. (2)
(c) Use the method of separation of variables and assume that ψ(x, y) = X(x)Y (y).
Rewrite the equation in terms of X and Y . (2)
(d) Divide by XY and solve for X00/X.
(e) Define a separation constant λ and write down the general solution for X(x). (2)
(f) Apply the boundary conditions in the x-dimension and obtain Xn(x). (4)
(g) Write down the general solution for Y (y). (2)
(h) Apply the boundary conditions in the y-dimension and obtain Ym(x). (3)
(i) Normalise ψnm(x, y). Make use of the fact that x and y are independent and that
the two integrals may thus be solved independently. (2)
(j) From the definition of k and using λ, obtain the discrete energies Enm. If we
define Enm ≡ Ex + Ey, write down expressions for the latter two terms

Four capacitors are placed within an 18.0 V circuit as follows:

Two capacitors 30.0 μF and 65.0 μF are connected in series with the battery, followed by two capacitors 45.0 μF and 80.0 μF connected in parallel.

1. You must draw and completely label the circuit.

2. Then find the charge stored on and the voltage across each capacitor within the circuit.

7) You add 25 g of milk at 10^o C to 200 g of coffee (essentially water) at 70^o C. The coffee is in a Styrofoam cup. If the specific heat of milk is 3800 J/kg*^oC, by how much will the coffee temperature decrease when the milk is added? Indicate any assumptions you made. The specific heat of water is 4180 J/kg*^oC,

8) The kayak of a 70-kg man tips and he falls into a cold stream. When he is rescued from the cold water, his body temperature is 33 °C (91.4 °F). He is placed in 50 kg of warm bath water at temperature 41 °C (105.8 °F). What is the final temperature of the man and the water?

As carried out in Section A, a 20 cm³ aliquot of a 0.0513 mol dm^-3 vanadium(V) solution wasreduced by excess zinc metal to an unknown oxidation state (x). The resulting lavender (lilac) coloured solution was then fully reoxidised by 32.3 cm³ of a 0.0199 mol dm^-3 KMnO₄solution.

Calculate the experimental value for the unknown oxidation state x (to two decimal places)

If a person of mass M simply moved forward with speed V, his kinetic energy would be 1/2MVsquared. However, in addition to possessing a forward motion, various parts of his body (such as the arms and legs) undergo rotation. Therefore, his total kinetic energy is the sum of the energy from his forward motion plus the rotational kinetic energy of his arms and legs. The purpose of this problem is to see how much this rotational motion contributes to the person's kinetic energy. Biomedical measurements show that the arms and hands together typically make up 13.0 % of a person's mass, while the legs and feet together account for 35.0 % . For a rough (but reasonable) calculation, we can model the arms and legs as thin uniform bars pivoting about the shoulder and hip, respectively. In a brisk walk, the arms and legs each move through an angle of about ±30∘ (a total of 60∘) from the vertical in approximately 1 second. We shall assume that they are held straight, rather than being bent, which is not quite true. Let us consider a 70.0 kg person walking at 6.00 km/h having arms 68.0 cm long and legs 90.0 cm long.

What is the average angular velocity of his arms and legs?

Using the average angular velocity from part A, calculate the amount of rotational kinetic energy in this person's arms and legs as he walks.

What is the total kinetic energy due to both his forward motion and his rotation?

What percentage of his kinetic energy is due to the rotation of his legs and arms?
