Problem 1. The resistivity of aluminum at 25°C has been measured to be 2.72 x 10-6 0 cm. Aluminum has a valency of 3, a density of 2.70 % and an atomic mass of 27 g. ст3 (a) Estimate their drift mobility, (b) Estimate the mean free time between collisions for the conduction electrons in aluminum at 25 °C, (make sure that the units in your calculation are correct and consistent) (c) If the mean speed of the conduction electrons is about 2 x 106 m/sec , calculate the mean free path.

I need an expert solution in MATLAB language for the question, and I need the solution to be using MATLAB and in the form of an image. I do not need any notes with the program, just an explanation at the end of the image. By the way, two questions. Q2. Write a MATLAB user-defined function, freefall(), that computes the velocity and the distance of a free fall object. The velocity and the distance of a free fall object can be written as: v = gt y = yo+gt² where yo is the initial position, t is the time travelled and g is the acceleration due to gravity (- 9.81 m/s2). Note that the initial position can only be a scalar value. Q7. Write a user-defined MATLAB Function for the following math function: ((xy-5)² z = if x, y > 0 elsewhere The inputs to the function are x and y, where the output is z. Write the function such that x and y can be vectors. I. II. Use the function to calculate z(3,4) and z(5, -7). Use the function to make a colored 3D plot of the function z for -5
Given the electrical circuit of the image:The value of the current passing through L2 is equal to zero (0).Answer the following questions:– 1. Is it possible to find an equivalent Thevenin resistance for L1? If so, list the steps to find it.– 2. Explain step by step, how would you find the value of the voltage v2, if we do not know the value of the current that passes through L1?– 3. What is the value of voltage v2, if the current passing through L1 is i(t) = 0.5 sin (60t – 90°)?
