Write a function that returns a square 2D Numpy array having the structure shown in the examples given below. The function should take the size of the matrix as the argument. Examples: Input: 5 Output: 1 0 1 0 1 2 0 2 0 0 3 0 3 2 1 4 0 0 0 0 5 4 3 2 1 Input: 10 Output: 1 0 1 0 1 0 1 0 1 0 2 0 2 0 2 0 2 0 2 1 3 0 3 0 3 0 3 0 0 0 4 0 4 0 4 0 4 3 2 1 5 0 5 0 5 0 0 0 0 0 6 0 6 0 6 5 4 3 2 1 7 0 7 0 0 0 0 0 0 0 8 0 8 7 6 5 4 3 2 1 9 0 0 0 0 0 0 0 0 0 10 9 8 7 6 5 4 3 2 1 Important notes: Your code will be evaluated automatically. If you do not comply with the following rules, your grade will be O!!!!!! • There will not be partial grading. If your code works correctly, you get a full grade. Otherwise, your grade will be O!!!! • You should write the algorithm yourself!!!! You are not allowed to use any readily available library function to perform the task described. • You should write your code as a single function that takes an integer and returns a 2D Numpy array as described. In addition, you should name your function as mat.

Amorphous Polymers, cont.d Example 3.1 Monomers A and B are copolymerized with the following results: Weight Fraction A in Polymer $T_g$ (°C) 1.000 108.0 0.850 75.0 0.260 28.0 $75 = \frac{0.85(108) - 0.150k(T_g)}{0.85 + 0.150k}$ $28 = \frac{0.26(108.0) - 0.7k(T_g)}{0.76 + 0.7k}$ $k(T_g)_B = 75k - 187 = 29.10^{-5}$ $k = 3.33 \quad and \quad \Delta(T_g) = 19.7$ $T_{g\text{ show}} = 0.5(108) + 0.5(-37) = 35.5$ What value of $k$ fits these data to Equation 3.20? If A forms a copolymer with equal weights of A and C, and the same $k$ applies, what $T_g$ can be expected? The $T_g$ of C is -37.0°C.

1. A particle is moving along a straight line such that its velocity is defined as v = (-4s-35) m/s, where s is in meters. If at t=0 s=3m, determine the velocity as a function of time, and determine the velocity when t=1s. (6 points) 2. The position of a particle that moves along the x-axis is defined by x = -3$t^2$ + 12t - 6m, where t is in seconds. For the time interval t=0 to t=3 s, (a) plot the position, velocity, and acceleration as functions of time; (b) calculate the distance traveled; (c) determine the displacement of the particle.
