You can and should start with the examples from the textbook/presentation and adapt them to the assignment at hand and use the appropriate names and add the additional code and requirements bellow. Design a program/project/driver class Your Name Assignment and the following classes (with exact names, replace Your Name with your actual first name or the name you go by): Class Description YourNameList Program the complete version of user-defined MyList class from Chapter 24 (meaning you need to add the code for all methods that were not coded in the textbook/presentation and have a "left as an exercise" comment). Add an additional YourNameToString method that returns a string with the elements from the list in the format: (Elementpositiono, ElementPostioni, .... Elementposition 1] YourNameArrayList Program a complete version of the user-defined MyArrayList class from Chapter 24 (all fields and methods) that uses the Your Namelist instead of MyList and has an tensiththaalam

4. Consider the determinant as a sum of signed products. Recall that there are \( n \) ! elementary products in the determinant expansion of an arbitrary \( n \times n \) matrix \( A \). (a) If \( A \) is a \( 5 \times 5 \) matrix, how many of the elementary products in \( \operatorname{det}(A) \) are guaranteed to be zero if the entry \( a_{12} \) is zero? (b) If \( A \) is an \( n \times n \) matrix, \( n \geq 2 \), how many of the elementary products in \( \operatorname{det}(A) \) are guaranteed to be zero if \( a_{12}=0 \) ? Give your answer in terms of \( n \). (c) If \( A \) is an \( n \times n \) matrix with \( \operatorname{det}(A) \neq 0 \), what is the maximum possible number of zero entries in A? Give your answer in terms of \( n \).

CIRCLE ALL ANSWERS AND PROVIDE UNITS 1. (20 points) Mohr's Circle and Stress Elements Oy An element in plane stress (shown above) is subjected to stresses Ox - 70 MPa, Oy, and Txy - 50 MPa. Using the Mohr's Circle equations, determine the following: a principal stresses, b. the maximum shear stress, C. the principal angle, d. If one of the principal stresses is negative, what does a negative stress mean? **Using just proper equations is acceptable, but Extra Credit will be given if Mohr's Circle is drawn out.

You make a swimming pool 3.92 M in magnesium acetate, Mg(CH3COO)2 hoping to keep it from freezing during the winter. Its density is 1.23 g/ml. What will its normal freezing point be? Give your final answer (remember, you're looking for the new normal freezing point) to 1 decimal place (just to keep CuLearn happy) Put C for your unit (I don't know how to find the degree sign for answers...) Kf(H2O) = 1.86 °C/m
