(b) Evaluate $\int_s \vec{f}.d\vec{s}$ where $\vec{f} = 2y\vec{j} + z\vec{k}$ & s is the surface of the cylinder $x^2 + y^2 = 4$ in the first octant, bounded by z = 0 & Z = L. (Replace L with the last digit of your matric no. For example, for a matric number 72342, L = 2, while for a matrix number with last digit is 0 value replace it to L=5, 72340, L=5). [10 Marks]

A rigid tank contains 1.6 kg of air at 250 K and 100 kPa. A paddle placed in the tank provides 1200 kJ of work, after which the pressure of air is measured to be 175 kPa. During this process, heat is released from the tank (Qout). Considering air as an ideal gas, assuming constant specific heat at 300 K, and the surroundings to be at 300 K, determine: (a) (5 points) The final temperature of the air [K], (b) (10 points) The amount of heat transfer from the tank, Qout [kJ], (c) (15 points) The entropy generation during this process [kJ/K].

Which of the following are true statements? Select one: A. In procuring production inputs, a spot exchange occurs when inputs are purchased "off-the-shelf" without a binding relationship between the buyer and seller. B. One advantage of using a spot exchange is there are relatively low transaction costs as long as the firm is using a standardized input. C. One disadvantage of a spot exchange is there is little or no quality control. D. All of the above.

Problem 8. a) Let $m: \mathbb{R}^3 \to \mathbb{R}$ be the map sending a vector to the square of its length: $m(x) = |x|^2$. Using the definition of derivative, or otherwise, compute $m'(y)$ for $y \in \mathbb{R}^3$. b) Suppose $f: \mathbb{R} \to \mathbb{R}^3$ is a differentiable map satisfying $|f(t)| = 1$ for all $t \in \mathbb{R}$. Show that $f'(t) \cdot f(t) = 0$ for all $t \in \mathbb{R}$.

2. A super special relativistic snake has a proper length of 100 cm. The snake is moving at 0.6c in the +x direction along a table relative to a mischievous boy. The boy declares \"I have learned special relativity and thus I know that I will observe the length of the snake to be contracted to 80 cm\" . He sets up an experiment to verify special relativity. He decides to bounce two hatchets, spaced 80 cm apart, on the table at the exact same time with the snake located between them. If special relativity is correct the snake is not harmed. If it is not, the snake will be chopped into pieces. The super special relativistic snake shouts \"Wait! I also know special relativity, and as I see your hatchets fly past me the distance between them will be contracted to even less than 80 cm and I am doomed!\" Use the Lorentz transformation to reconcile this problem. I have given some possible helpful steps to follow below. a. What are you going to call \"Event A\" and \"Event B\"? b. Determine the position and time coordinates (x, t) for each of the two events as viewed by the boy. I would set x=0 to be the position of the snake's tail at t=0, when the boy bounces the two hatchets. c. Determine the position and time coordinates for the same two events as viewed by the snake. d. Explain how special relativity is indeed correct, yet the snake does not get chopped into pieces as he suspects.
